Tinnitus masking is carried out by providing an external sound that reduces the annoyance of the tinnitus through either disguising it, suppressing it, or making it more pleasant. Controlled studies of maskers have shown small effects (Dobie, 1999), and a recent Cochran review (Hobson et al, 2012), suggested that there was limited data, poor studies, and lack of strong evidence of an effect.
The purpose of testing for tinnitus is to assess hearing, and tinnitus matching -- to quantify the tinnitus.
The most effective way to do masking is to find out what type of noise suppresses your tinnitus (if any), and then make arrangements to expose yourself to this noise. One may also go about this in a formal way -- measure your tinnitus, determine if a hearing aid is needed, determine the masking sound that works, and implement a masking stimulus using some sort of personal sound playback system.
Hearing aids can be bought with masking stimuli built in, or with blue-tooth that allows one to broadcast masking to one's hearing aid.
The main way that this approach differs from conventional masking is that the sound is filtered, and customized to the tinnitus frequency. Strauss et al (2015) reported another type of masking, using a notch filter that removes sound at the tinnitus frequency from hearing aids might be helpful.
An underlying blood vessel disorder that increases pressure in the blood vessels that supply blood to the middle and inner ears may cause tinnitus. When tinnitus is caused by certain medications, stopping these drugs heals tinnitus naturally. Dysfunction of the auditory pathway that leads to tinnitus is frequently attributed to vitamin B12 deficiency. When tinnitus is caused by poor circulation, gingko biloba may help to treat the condition. People with Tinnitus, live with constant or intermittent sounds (often referred to as ringing in the ears, even though the sound may come in a variety of tones) which is not produced by an external source(s).
Maskers seem to be effective for some people but not for all and whilst it doesn’t cure your tinnitus and you actually now have just a more pleasant sound to listen to all the time, it has had some success in providing some relief for sufferers.

Definition: Tinnitus could be defined as perception of noise in the absence of acoustic stimuli. Prevalance: Studies have shown that nearly 20% of adults experience tinnitus in one form or the other. Hearing loss: Studies conducted in Canada showed people with deafness had increased incidence of tinnitus. Tinnitus in children: Increased incidence of otitis media in pediatric age group plays an important role in high prevalance of tinnitus in children. Classification of tinnitus: One simplistic classification of tinnitus could be Subjective and Objective tinnitus. Pulsatile tinnitus: May be classified into vascular and non vascular types according to its etiology.
Non vascular types of pulsatile tinnitus include palatal myoclonus, tensor tympani myoclonus, and stapedial myoclonus.
Classification schemes available: Various classification schemes have been suggested by various authors. Nodar's classification: This classification was based on the importance of 6 factors related to tinnitus. Modified Nodar's classification: In 1996 Nodar came out with a new version of his classification. Subjective tinnitus can be compared to phantom sensations which occur after amputation of limb. Auditory feed back system and its role in tinnitus generation: The optimal operation of auditory system is dependent on very sensitive and complex feed back mechanisms involving the afferent (ascending), efferent (descending) pathways. Nervous system as the site of tinnitus: Most forms of severe tinnitus have been shown to be caused by abnormal functioning of the nervous system.
Vascular contact with the intracranial portion of auditory nerve is regularly associated with tinnitus.


A good history is a must for accurate diagnosis of the underlying pathology leading on to tinnitus. Etiology of objective tinnitus include: intracranial vascular anamolies, atherosclerosis of aorta, pseudotumor cerebri, chemodectomas involving the middle ear. Pitch estimation: Pitch estimation of tinnitus helps in the probable etiology for tinnitus. Masking: Refers to the reduction of audibility of tinnitus when the patient is exposed to another sound.
Nevertheless, from our own clinical experience with treating tinnitus, we think that masking is the most effective treatment of tinnitus. The stimulus is raised in 5 db steps and patients are asked whether their tinnitus is still audible. This is a collection of 6 CD's found by Mike Petroff, an individual with tinnitus, to be helpful for him, and marketed for this purpose. This can be expensive, as they provide the same function as an app on your smartphone, but cost more than 5 smartphones put together (but of course no contract !). It is difficult to see how this approach is technically superior to the smartphone app approach. This makes the masking sound less disturbing as it does not contain useless frequencies (Paglialonga et al, 2011). We are dubious - -it is of course impossible to placebo control two different audible interventions. An underlying ear problem that affects the auditory nerve is primarily responsible for this condition.
Atherosclerosis, hypertension, tumors in the head or neck and narrowing of an artery or vein in the neck are often linked to tinnitus.
Tinnitus can be the side effect of certain antibiotics, diuretics, malaria medications, cancer drugs and high doses of aspirin. Relaxation therapy, moderate physical activities and biofeedback can alleviate the discomfort. Researchers have observed that nearly 47 percent of all patients with tinnitus have low vitamin B12 serum levels.
Studies have shown that gingko biloba boosts blood circulation, which helps to reduce the loudness and discomfort of tinnitus. Managing tinnitus through tinnitus retraining therapy helps a person suffering from tinnitus to become accustomed to the persistent ringing sound in the ear.¬†When common treatments fail to heal tinnitus, you may consider wearing an electronic device that produces low-level environmental sound or music that masks the ringing sound in the ear. Because the noise being heard isn’t external we cannot simply turn off the offending noise generator or remove the sufferer from the are where the noise is being produced. Factors affecting the prevalance of tinnitus include: age, gender, race, economic status, hearing loss and noise exposure.
Patients belonging to otologic category include those with disease of external or middle ear, cerumen impaction, abnormal mobility of ear drum or ossicular chain, and abnormal contractions of the middle ear musculature. It includes history and physical examination, audiological testing, vestibular evaluation and radiologic studies. Alteration in the stereocilia that are attached to the outer hair cells could be the exact cause. The auditory pathway is also linked with other extra auditory structures like reticular (serotonergic), somatosensory, hypothalamic and limbic systems thus making a tight integration with the central nervous system network. This disorder includes a triad of symptoms which include fluctuating hearing loss, roaring tinnitus and vertigo. Noise and ototoxic drugs cause damage to hair cells of cochlea depriving auditory input to the brain. Infact tinnitus could be the first symptom of a vestibular schwannoma, it becomes worse after surgical removal of schwannoma.
Severity of tinnitus should be assessed (ie whether present throughout the day - severe tinnitus, present only in the absence of ambient noise - night times - mild tinnitus). Tympanometry and stapedial reflex test - to identify middle ear pathology and evaluate the neural pathway for stapedial reflex.


High pitched tinnitus is common in patients with noise induced hearing loss, and low pitched tinnitus is commonly seen in Menier's disease. If you need a hearing aid or have one already with bluetooth, this is a cheap way to go about it. Treating the underlying vascular condition with medications or surgery heals tinnitus naturally. Wearing the device for several weeks helps to reduce the discomfort and loudness of tinnitus.
Cochlear evaluation include: pure tone audiometry, auditory brain stem response, speech audiometry, tone decay testing and tests for recruitment. The term ABC denotes aurium (one ear), binaural (two ears), and cerebri (centered in the head). The stiffness of the stereocilia is altered causing its decoupling from the tectorial membrane. This indicates that tinnitus could be generated by the brain in response to lack of normal stimuli from the auditory system. This type of tinnitus occur due to irritation to the nerve by the offending vessel (kindling phenomenon). This type of hallucinations occur in patients with psychiatric disorders like schizophrenia. Subjective tinnitus is usually high pitched and ringing in nature and can only be perceived by the patient. In Meniere's disease it is low frequency, while in noise indued tinnitus it is of high frequency.
Measurments of tinnitus include assessment of the pitch, bandwidth, loudness, maskability of tinnitus and residual inhibition. In tinnitus loudness match the patient is instructed to match the loudness of tinnitus with that of narrow band noise generated at about the same frequency as the tinnitus. Sometimes treatment for tinnitus focuses on masking the noise in the ear to make it less noticeable. To soften the wax, pour few drops of glycerin, baby oil, mineral oil or hydrogen peroxide in the ear canal, twice each day, for up to five days. After the wax softens, it may gradually fall out of the ear.
It essentially is replacing one sound with a more pleasant one, this in turn distracts the wearer from the offending sound and makes life a little less stressful. Venous causes include benign intracranial hypertension, high jugular bulb and hydrocephalus. These features are caused by changes in the function of nuclei in the ascending pathways, or by redirection of information to regions of CNS that normally donot receive inputs from the auditory system. Whereas objective tinnitus is commonly pulsatile in nature and is also heard by the examiner. Squirting lukewarm water into the ear canal and tilting the head on the side to drain out the water helps to remove the soft plug from the ear..
The main advantage of this scheme is that the physician need to choose from only two options under each descriptive category. A single pure tone masking tone of any frequency may mask a broad band spectrum of tinnitus. It is still rather labor intensive though as it requires tinnitus matching, creating a customized sound file, and mixing in the sound file with background music.
Bad plasticity causes hypersensitivity and hyperacitivity by redirecting information to other parts of central nervous system by unmasking dormant synapses.
It has also been suggested that phase locking of the activity in many nerve fibers can also be a cause for tinnitus.
