Ringing in ears do not cause hearing loss and in fact the person becomes highly sensitive to even small sound. Other factors like frequent ear infections and formation of tumor in the ear can cause tinnitus.
Certain medical conditions like Meniere’s disease, otosclerosis, high blood pressure, anemia, diabetes, thyroid problems and allergies can cause tinnitus.
In case tumor is the root cause of the problem surgery is to be done for removing the tumor.

Whether it sounds like ringing, buzzing, hissing, chirping or whistling, if you’re constantly hearing sounds like these in your ears when no noise is present, it might be more than just a remnant from the loud concert you attended the night before. Even though tinnitus is commonly associated with hearing loss, it’s actually a symptom of another underlying condition. That’s why, if you have tinnitus, the first thing you need to do is find a hearing healthcare professional who has experience treating tinnitus patients.
One of the first things a hearing health professional will do is ask about your tinnitus history. One common cause of tinnitus is damage to the hair cells of the inner ear due to age or exposure to loud noise.
Because tinnitus is often caused from prolonged exposure to excessive noise, military personnel aren’t the only ones at risk for developing this condition.
Other causes of tinnitus include Meniere’s disease, TMJ disorders, head or neck injuries and acoustic neuroma.
Others who don’t have hearing loss severe enough to warrant wearing hearing aids may benefit from smart phone apps. At its meanest, tinnitus can cause sleep deprivation and fatigue, stress, concentration and memory problems, depression, anxiety and irritability. INTRODUCTION: The general consensus on the roles of hearing loss in triggering tinnitus seems not applicable in patients with normal hearing thresholds. OBJECTIVE: To scrutinize auditory functioning in a sample of tinnitus subjects with normal hearing thresholds and non-tinnitus normally hearing control participants using transient evoked and distortion product otoacoustic emission (TEOAE and DPOAE) and Threshold Equalising Noise (TEN) test.
METHODS: Twenty-seven tinnitus adult patients with normal hearing thresholds and 27 normally hearing volunteers were tested with TEOAE, DPOAE and TEN test.
CONCLUSION: These results suggest the possible existence of subtle auditory deficit in normally hearing tinnitus patients, which may be an early sign of diseases that are only diagnosed after the onset of hearing loss. Keywords: coustic neuroma, otoacoustic emissions, tinnitus, threshold equalising noise test. Tinnitus is defined as the perception of sound that results completely from activity within the nervous system without any corresponding mechanical, vibratory activity within the cochlea, and not related to external stimulation of any kind1. An increasing amount of epidemiology studies provide both self-reported data on tinnitus and hearing status which allows closer examination on the relationship between tinnitus and hearing status.
Although some studies have different theoretical assumptions and approaches, the significance of hearing loss in tinnitus generation is not questioned. Thus, several attempts have been made to explain pathophysiology mechanisms of tinnitus in patients with normal hearing ability particularly using otoacoustic emissions (OAEs).
Several studies have revealed that TEOAEs and DPOAEs can be used as a tool to detect early hearing loss before it can be diagnosed by PTA13-15. The contradict findings from previous research motivates researchers to find alternative theories to explain tinnitus mechanisms in tinnitus patients with normal hearing thresholds. This study investigated 27 tinnitus subjects (42 tinnitus ears and 12 contralateral non-tinnitus ear) with normal hearing thresholds who were recruited from Welsh Hearing Institute, University Hospital of Wales.
Full history taking and otoscopy examination were carried out at the beginning of the session. TEOAEs test was performed using unfiltered clicks of 80 µs duration presented in non-linear modes. The stimulus comprised of a pair of primary pure tones (f1 and f2) at a frequency ratio equal to 1.22.
The basic principle of this test is to control for "off-frequency listening" from occurring by using a broad band noise (the threshold equalising noise).
This research has received the ethical approvals from the School of Applied Community and Health Studies (SACHS), University of Bristol Human Participants Ethics Committee and the South East Wales Research Ethics Committee.
Initially, the left and right of DPOAE results were compared within the tinnitus and control groups. Then, the differences of overall mean DPOAE amplitude between tinnitus and control ear were compared.
Various hypotheses have been put forward to explain tinnitus generation in normal hearing patients. Decreased TEOAE amplitudes were observed in 35.7% of the tinnitus subjects with normal hearing sensitivity. A statistically significant increase in DPOAE amplitude was observed in tinnitus ears at f2 frequency of 1414 Hz. The fact that tinnitus patients with normal hearing have a significantly higher percentage of abnormal TEOAEs and a limited frequency of DPOAE than the controls may suggest that OHC dysfunction may be pivotal in tinnitus generation. In the current study, the percentage between abnormal TEOAE and DPOAE in both groups had no statistically significant difference. In the field of tinnitus, however, only two studies reported the application of TEN(HL) test in tinnitus patients with normal hearing24,25. Based on systematic review, no research on the application of TEN test in detecting acoustic neuroma has been published. No published data was found on the application of a TEN test in detecting acoustic neuroma. This study showed that subtle cochlear problem may exist in tinnitus patients before it is significantly appeared in the audiogram.

Sensorineural hearing loss can occur for many reasons, such as after a viral infection, noise damage, and occasionally small growths that compress the hearing nerve can lead to hearing loss, tinnitus, or balance problems. An assessment that consists of taking a good history, a thorough examination, and various hearing tests usually points to the correct diagnosis. An eardrum can get a hole in it as a result of infection, trauma, or diseases such as cholesteatoma (see below). This is a good operation for those having problems with recurrent discharge, or those that are keen on swimming.
If the eardrum is not normal, and has a perforation (hole) or a retraction pocket, the skin can collect in the middle ear. If you have any hearing loss associated with ear discharge, pain, or balance problems, it is a good idea to get a check up from an ENT specialist. Mr Sunkaraneni is a UK trained Ear, Nose and Throat (ENT) Surgeon who graduated from the University of London. Some people may find it annoying and it can affect their quality sleep also causing psychological problems. Intake of drugs like strong antibiotics, aspirin, sedatives and prolonged use of antidepressant medications can cause tinnitus. He may check for neck or head injury and order for imaging tests like X-ray, CT or MRI scanning. Medications like alprazolam and other benzodiazepine drugs, corticosteroid drugs, and Cytotec and other prostaglandin drugs are recommended for treating tinnitus. While all hearing healthcare professionals can test hearing and diagnose hearing loss, only those with special training in the treatment of tinnitus can alleviate your symptoms. In fact, according to the Department of Defense’s Hearing Center of Excellence, tinnitus is one of the top disabilities associated with our military veterans, affecting more than 350,000 service members.
Those who work in the music industry, such as rock musicians, technicians and aficionados are also at risk. Medications such as antibiotics, cancer medications, diuretics, certain antidepressants and aspirin can cause or worsen tinnitus. If your ear canal is filled with earwax, removing the impaction may dramatically decrease your symptoms.

Measurement of subtle auditory deficit in tinnitus patients with normal audiometric thresholds using evoked otoacoustic emissions and threshold equalizing noise tests. The absence of hearing loss on the audiogram in this group of patients poses a serious challenge to the cochlear theories in explaining tinnitus generation in this group of patients. For many years, progress towards finding the effective treatments for tinnitus was hindered by vague understanding of its underlying pathologic mechanisms. The association between hearing loss and tinnitus has been well documented in the previous literature2-4.
Some studies found a correlation between severity of tinnitus and degree of hearing loss3,8 while others found no such correlation9. On the other hand, clinical observations have shown that 8 to 10 per cent of tinnitus patients had normal audiometric thresholds12. It is hypothesised that outer hair cells damage results in stereocilia decoupling from the tectorial membrane, thus causing them to depolarise and subsequently resulting in tinnitus perception1.


An association of tinnitus with the changes in amplitude of TEOAEs and DPOAEs has been reported.
One study by Weisz et al.24 proposed that subtle auditory abnormality may also arise from the inner hair cells (IHCs) dysfunction. The subjects who were attending the Institute from January to December 2010, were identified by an audiology physician and audiologists based in this hospital. Then, all subjects underwent basic audiological tests which include pure tone audiometry and tympanometry. Off-frequency listening occurs when the presented stimulus is being picked up by other parts of the cochlea instead of the targeted frequency area of the cochlea. From the analysis, the parameters of the TEOAEs for tinnitus ears are not significantly different from the control ears. Since no statistically significant difference was observed between both ears, further statistical analyses were performed using combined data from both sides together. Distribution of the number of test frequencies with abnormal DPOAE in tinnitus and control ears. Based on the chi-square analysis, tinnitus ears have a statistically significant higher percentage of abnormal DPOAEs at some frequencies, mainly at 2000 and 4000 Hz regions (Table 4).
For example, it has been postulated that the different level of functionality between OHCs and IHCs (the Jastreboff's discordant dysfunction theory) can generate an unbalanced stimulation of dorsal cochlear nucleus's cells which produces abnormal neural activity.
Abnormal DPOAE amplitudes were also found in this group, particularly at high frequency regions, but in a slightly lower percentage than the TEOAE.
For example, in Shiomi et al.19, the mean amplitudes of the DPOAE were significantly decreased in tinnitus patients with normal hearing than in normally hearing controls.
One possible explanation for this finding is that it may be due to OHCs hypersensitivity, as reported in some previous research. Abnormal TEOAEs and DPOAE in the tinnitus patients also imply that they may have subtle cochlear damage that is not yet appearing on the audiogram. This finding might suggest that both tests were sensitive to detect minor OHCs dysfunction. Unexpectedly, the use of a TEN test in the current study has led us to find an acoustic neuroma in a patient.

Occasionally a special type of scan called an MRI (magnetic resonance imaging) scan may be required. However, sometimes they can leak fluid (discharge) from the middle ear, and they may be responsible for a degree of hearing loss (depending on its size and position). With a normal eardrum, this skin migrates to the edge of the eardrum, and out of the ear canal, from where it is shed.
Usually, surgery is required to remove the cholesteatoma and repair any damage to the hearing bones in the middle ear. During his medical school training, he spent a year undertaking a Bachelor’s degree in Clinical Anatomy, where his interest in the anatomy and surgery of the head and neck region began. The frequency of noise may vary from low to high pitch and it can be heard now and then or as continuous stretch. For some people in addition to loud noise, they can get ear pain and difficulty in sleeping due to stress. Retraining therapy is given for tinnitus to get back the normal sensation in the nerve path of the ears.
And, even though it’s just a common annoyance for some, those who suffer from extreme cases have trouble concentrating, sleeping, working and even maintaining relationships. The challenge is to keep searching until you find a hearing health professional who is skilled at working with tinnitus patients.
So are those who work with loud equipment, like carpenters, landscapers and road construction crew members.
Only one patient was found with a positive TEN test result, who was confirmed by Magnetic Resonance Imaging to have acoustic neuroma on the affected ear.
The last half of the twentieth century saw considerable advances in our understanding of tinnitus from both physiological and psychological perspectives. It has been generally accepted that any severe damage along the auditory system may lead to a certain degree of hearing loss, which is generally associated with tinnitus5,6.
Moreover, the incidence of tinnitus in patients with sensorineural hearing loss varies widely across studies. These observations may have several indications, such as hearing loss is not necessary in tinnitus generation, pure tone audiogram does not always indicate auditory damage, tinnitus may be a primary symptom of diseases that are only diagnosed after the occurrence of hearing loss, or several mechanisms exist in a group of patients. The different functionality of outer and inner hair cells can also cause imbalanced activity in the dorsal cochlear nucleus which in turn causes changes at higher levels of the auditory system that may be perceived as tinnitus1. In some studies, lower amplitude of TEOAEs13,16 or DPOAEs13,17-19 have been observed in tinnitus patients compared to in non-tinnitus controls.
All participants had no history or current external and middle ear problem, noise exposure and psychiatric problem. In this experiment, a 2f1 - f2 distortion product was used because of its established clinical value.
This off frequency listening occurs when the targeted area of inner hair cells or neurons are not functioning well and is referred to as a dead region27.
In this case (Subject RX), the TEN (HL) test revealed that dead regions might exist at 1.5, 3 and 4 kHz on the left ear (Table 7).
Since all the subjects in this study had normal hearing, the decrease in the TEOAE and DPOAE finding may possibly be considered as the effect of cochlear dysfunction of the cochlear active mechanism, which is related to OAE generation.
Frequency analysis also showed that a significant decrease in DPOAE amplitude was mainly at the f2 frequency of 4000 to 7000 kHz. Therefore, the hearing status of these patients should be monitored for possibility of developing hearing loss later in life. Previous research has clearly demonstrated that OAE may be used to reveal subclinical OHCs damage in audiometrically normal ears13-15. Apart from difficulty hearing in background noise, she did not have any other classical symptoms of acoustic neuroma such as balance problem or poor speech discrimination scores. Firstly, it implies that a TEN test may offer a quick, inexpensive and non-invasive method for retrocochlear screening. In their study, they found 7 out of 8 auditory neuropathy patients with abnormal TEN test results.
The finding also supported the possible clinical advantage of the TEN test as a screening tool for retrocochlear problem.

Cerumen is produced by glands in the outer part of the ear canal called ceruminous glands (a modified sweat gland).
This is where the wax is removed in a controlled manner under direct vision using a microscope. Treatment for ringing in ears is available in the form of medications, surgery, using masking device etc. For instance, musicians, carpenters, pilots and landscapers are at high risk for developing tinnitus since their work involves hearing loud noise most of the time. Wear and tear of the inner cells of the ear can lead to deterioration of the cochlea of the ear.
If any medications are causing such noise in the ear, your GP may provide suitable alternative for the problem. You may be hearing what other people do not hear and sometimes you will be able to hear only loud frequency sound and not normal sound. If current prescription is the culprit, your doctor may be able to reduce your dosage or switch you to a different medication. The program also includes personalized support, education and monitoring from an audiologist specializing in tinnitus. More commonly, various studies have shown that sensorineural hearing loss plays an important role in tinnitus generation. Therefore, the absence of hearing loss on the audiogram in this group poses a serious challenge to the aforementioned theories in explaining tinnitus generation in tinnitus patients with normal hearing.
In the study, they investigated the inner hair cells functions in 11 chronic tinnitus patients with normal hearing thresholds using Threshold Equalising Noise (TEN) test and found 8 of them with possible inner hair cells problems.


The results were presented as a distortion-product audiogram i.e the amplitude of the 2f1 - f2 DPOAE was plotted against the f2 from 1000 to 6169 Hz. The broad band noise is designed to produce almost equal masked thresholds over a wide frequency range, for listeners with normal hearing and hearing impairment but without dead regions28.
The abnormal TEOAEs in the tinnitus group were present for 1 and 4 kHz mostly, while in the control group, the abnormalities were mostly at 4 kHz. A t-test revealed that with regard to mean amplitude of TEOAE for tinnitus ears, there were no statistically significant differences for all frequencies tested (p > 0.05).
Later, the mean amplitude of DPOAE for tinnitus and control ears against the corresponding f2 was compared. From 20 tinnitus patients with abnormal OAEs, 13 of them exhibit either failed TEOAE or DPOAE results. According to this theory, discordant dysfunction can occur without affecting the audiometric hearing thresholds when the OHCs are partially damaged and where the IHCs are intact. Stated differently, abnormal or poor OAE results may be the indicator of subtle cochlear damage before the abnormality affects hearing sensitivity and appears on the audiogram. Thus, the similar findings indicate that DPOAE measurement can offer a frequency specific measurement for the detection of subtle localised cochlear damage even before affecting pure tone thresholds34. The high percentage of TEOAE abnormality at 4 kHz for the control ears may suggest that the hearing status of these participants also needs to be monitored. Nonetheless, only the difference between numbers of abnormal TEOAE in tinnitus and control ears reached a statistically significant level. The former study suggested that tinnitus generation in their group of participants may be due to the effect of deafferentation of the neuron. Secondly, tinnitus patients may have a serious problem that triggers the tinnitus perception despite having normal hearing thresholds and normal OAE test results. Patients with auditory neuropathy are known to have problems with transmission of the auditory signal to the brain, thus abnormal TEN test results in this group of patients were assumed to be due to the neuron dysfunction.
However, more research needs to be carried out in this area in order to support the current finding.
This can cause irritation to the affected person and in severe cases it can affect your potential at workplace or your relationships.
People whose job involves gun making and other musical instruments can also develop this condition. If buildup of ear wax and infection is causing tinnitus, he may thoroughly clean your ears.
Tinnitus can be more nuisance particularly during night when there is complete silence around. Evidence showed a higher incidence of tinnitus patients with sensorineural hearing loss compared with conductive hearing loss7.
In addition, not all individuals with hearing loss experience tinnitus, and not all tinnitus patients have hearing loss. While the theories seem cannot fit in this minority group, evidence obtained from this group may have huge implication for a better tinnitus mechanisms understanding as well as assist in developing and shaping tinnitus management.
The studies reported that tinnitus subjects were found to have increased TEOAEs20,21 or DPOAEs22,23 compared with non-tinnitus counterparts. Thabet25 attempted to replicated the earlier study by investigating 20 normally hearing unilateral tinnitus patients with TEN test and TEOAE.
The presence of DP amplitude was accepted as valid when the signal to + 2 SD noise floor ratio exceeded 3 dB and the absolute DPOAE amplitude was at least - 10 dB SPL at each individual f2.
Table 2 shows the normal and abnormal TEOAEs at each frequency tested in both the tinnitus and control group.
Generally, an independent t-test showed no statistically significant differences observed between tinnitus and control ears at all frequencies except for frequency 1414, 4757, 5187 and 6169 Hz (Table 5).
Meanwhile, from 16 control ears with abnormal OAEs, 10 ears exhibit either failed TEOAE or DPOAE results. The ABR showed absent wave V at 70 dBnHL in the left ear and normal ABR waveforms in the right ear, which were correlated with the TEN test results, suggesting of abnormal neural function. Therefore, in this current study, we sought to determine whether the measurement of TEOAE and DPOAE may reveal subtle cochlear abnormality in tinnitus patients with normal audiometric thresholds.
Although the difference between numbers of abnormal DPOAE in tinnitus and control ears failed to reach a significant level, mean amplitude of tinnitus ears at frequency region of 2000 and 4000 Hz were statistically significantly lower than the control ears. They suggested that it could be the result of reduced afferent input to the central auditory system due to cochlear lesion, thus resulting in a decreased OHC efferent activity and ultimately leading to OHC hypersensitivity. TEOAE measurement stimulates the whole basilar membrane of the cochlear, which means it gives more global information. Furthermore, dead regions normally exist in those who have hearing thresholds of 60 dB HL and above28. In other words, even though dead regions normally exist in patients with hearing loss of more than 55 dBHL, normal hearing people can also have a 'dead region' which may be due to retrocochlear abnormality. Similarly, the abnormal result in Subject RX in the current study may also be because of the problem in neurons rather than in the inner hair cells. MRI revealed a large vestibular schwannoma in the left cerebello-pontine angle which was compressiong the brainstem and cisternal portion of the VIIIth cranial nerve.This study showed that subtle cochlear problem may exist in tinnitus patients before it is significantly appeared in the audiogram.
Jastreboff & Jastreboff11 reported that about 27% of totally deaf patients do not have tinnitus, whereas 20% of normal hearing people have tinnitus. This is because the results obtained from this special group may directly related to the tinnitus perception, but not to the concomitant hearing loss. The test was performed in a sound treated room where the ambient noise was maintained between 20 to 40 dB A. The difference between the two groups is highly significant at frequencies of 1, 1.5 and 2 kHz, but not at 3 and 4 kHz.
The decrease in DPOAEs amplitude over a limited frequency range in DP-gram found in tinnitus patients with normal hearing may be a susceptible area representing minor cochlear pathology. Similarly, a more recent study by Sztuka et al.35 attributed the increase in DPOAE amplitude in tinnitus patients with normal hearing as a result of increased motility of the OHCs due to decreased neural activity in the auditory nerve. Conversely, the number of abnormal DPOAE in tinnitus ears was not statistically significantly different from the controls.
They found that outer hair cells damage (assessed by TEOAE) was more common in normally hearing tinnitus patients than inner hair cells damage. In this case, the positive TEN (HL) results may not be due to inner hair cells damage but maybe because of poor processing efficiency that is associated with neural problems due to compression of large vestibular schwannoma on the VIIIth nerve38. However, caution should be taken in interpreting the TEN test results as 10 dB-above-thresholds criteria is just a binary criteria that means passing or failing the TEN test, but does not mean dead or not dead.
It can be assumed that the role of sensorineural hearing loss as a tinnitus generator is complex and the mechanism of tinnitus may rely on the presence of other contributing factors such as damage to specific hair cells or the auditory nerve fibers. This appears to support the hypothesis that a reinforced mechanical distortion is generated by cochlear hyperactivity that can be the source of the tinnitus. DPOAE is more frequency specific and thus is expected to be more sensitive in detecting subclinical abnormality in cochlear function over TEOAE. Their finding supports the theory that outer hair cells abnormality may be an important factor in the tinnitus mechanism37. For this reason, more research needs to be carried out on the clinical benefit of the TEN test before applying this method clinically. By contrast, in other cases, TEOAE and DPOAE results showed poor or absent emissions in tinnitus patients with sensorineural hearing loss, even in those ears with normal hearing16,19,36.
In this current study, the result may possibly be due to subtle cochlear abnormality also existing in non-tinnitus participants with normal hearing.
However, results from both studies may be more compelling if they included a retrocochlear test. The TEN test appears to be a potential non-invasive and quick test of inner hair cells function.
The mean pure tone audiometric thresholds of tinnitus and control groups are shown in Table 1. The tumour was compressing the brainstem and cisternal portion of the VIIIth cranial nerve. These variations can be explained by postulating that it is most likely to reflect different cochlear mechanisms underlying tinnitus generation due to different cochlear pathological changes in tinnitus ears37. The result of the current study is consistent with Thabet's study in which only one subject was found with a dead region, on the left ear. Nonetheless, it is too early to make a conclusion based on the aforementioned two studies on tinnitus. An independent t-test revealed that there was no significant difference in hearing thresholds between tinnitus patients and controls at all frequencies except at 6 and 8 kHz. Thus, the variability of findings in this study may possibly be because of different mechanisms existing in the normally hearing tinnitus patients.
According to Jastreboff37 however, there are different levels of dysfunction from the OHC up to the higher auditory pathways. At both these frequencies, tinnitus patients had significantly higher thresholds than control individuals. He hypothesised that in some patients, though the level of dysfunction is undetectable by TEOAE, it may be sufficient to produce tinnitus. Therefore, this study aimed to investigate subtle cochlear abnormality in tinnitus patients with normal hearing thresholds using evoked OAEs (TEOAEs and DPOAEs) and TEN test. Contrarily, in some, the level of abnormality is detectable but not enough to trigger tinnitus. Therefore, Jastreboff's hypothesis is a possible explanation as to why not all hearing loss patients present with tinnitus, and not all tinnitus patients present with hearing loss.
