The professionals at Advanced Hearing Aid Clinic and Advanced Hearing and Balance Institute believe that a comprehensive understanding of tinnitus will help individuals explore treatment options, learn new coping skills, and feel more positive about the future. Most cases of tinnitus are subjective, meaning that only the person who suffers from tinnitus can hear it. However, there have been documented cases of objective tinnitus, where sounds can actually be heard from the ear. Tinnitus can occur in one or both ears, constantly or intermittently, perceived to be occurring inside or outside the ear(s), be progressive, pulsing, or vary in intensity or pitch. Feelings of pressure (aural fullness) or pain in or around the ears may accompany tinnitus.
Tinnitus can be very mild during the daytime but more noticeable in quieter situations (quiet room or bedtime), as daytime activities and surrounding sounds can act as a distraction and serve to mask or partially mask tinnitus. The occurrence and intensity of tinnitus may vary depending on several factors such as stress, diet, and noise exposure.
It is estimated that 25 million Americans experience tinnitus to some degree on an ongoing basis.
The Canadian Tinnitus Association has estimated that 360,000 Canadians are annoyed by their tinnitus, and that approximately 150,000 find that tinnitus seriously impairs the quality of affected individual's lives. The Canadian Academy of Audiology estimates that 10 to 15% of Canadians suffer from tinnitus (approximately 3 million) with 20% of these individuals seeking help for their condition because their tinnitus is so severe that it is debilitating (approximately 600,000 individuals).
Tinnitus can be a symptom of a condition that is related to many forms of hearing loss, or it may exist without hearing loss.
Atherosclerosis is a large buildup of cholesterol and other fatty deposits in major blood vessels close to your middle and inner ear. Although there are many theories about how sounds in the ears or head are produced, the exact process is not fully understood.
When healthy, the hairs on top of the hair cells move as a result of the pressure of sound waves moving through the fluid in the inner ear.
Since tinnitus is a symptom, the first step in finding some form of resolution should be to try to determine or diagnose the underlying cause.
Our doctoral level audiologists have taken post-graduate training in tinnitus and tinnitus management. Our clinics have one of the most comprehensive protocols for tinnitus assessments in Canada.
The first test involves conventional pure tone testing to determine if there is a hearing loss. One of our Audiologists will also perform tests of residual inhibition to try to determine what treatment method would be most beneficial to you.
Auditory brainstem response testing can be done to rule out tumours on the vestibular nerve. Typically, once a comprehensive evaluation has been performed, most individuals who suffer from tinnitus feel reassured and find it somewhat easier to adjust and adapt to the tinnitus.
Not all Canadian Audiologists are trained in tinnitus and hyperacusis management or the most recent therapeutic interventions. If you work in loud noise or partake in loud recreational noise, wear ear effective ear protection. As you can see below, there are a variety of types of hearing protection - all purpose, or custom that may be appropriate.
Deep breathing, hypnosis, biofeedback, systematic relaxation, therapeutic massage, yoga, and some forms of physical exercise such as swimming or walking can reduce tension, stimulate endorphins, and promote better sleep. Alternative approaches (naturopathy, acupuncture, vitamin, and mineral supplements) have been of limited use in treating or reducing tinnitus.
This type of loss is due to the inability of sound to pass through the outer and middle ear.
This type of hearing loss occurs when there is damage to the cochlea (inner ear) or to the auditory nerve that goes to the brain. Without amplification, the child can hear most conversations up close and in quiet environments, but is likely to miss parts of words. Until recently, children with unilateral hearing loss did not have their hearing loss detected until they were in school. The audiogram is a graph that represents how loud a sound at a specific pitch has to be for the child to hear the sound. Configuration of hearing loss - is the shape of the hearing loss due to the amount of hearing loss at each frequency.
Hair cells are the sensory receptors located within the organ of Corti on a thin basilar membrane in the cochlea of the inner ear.
Two years of interviews with the leading innovators in concert, theatre, and corporate production, all in one great book with a foreword by Bob McCarthy. Here is a collection of assembled wisdom and experience that I believe will open up your mind to how you can expand your role in the audio professional network.
Tinnitus is a perception of sound in the ears or the head when no external sound source is present. While the perception of tinnitus is real, there is no external sound corresponding to the patient's perception of sound, and thus tinnitus is classified as a phantom auditory perception.
Individuals with more severe cases of tinnitus may find it difficult to hear, work, or sleep.


Increased activity in the absence of daytime sounds can seem to make the tinnitus louder although the intensity doesn't actually vary. Individuals may report similar characteristics of tinnitus but may be affected by it in a significantly different manner. Almost every individual has, at one time or another, experienced brief episodes of mild ringing or other sounds in the ear. The blood vessels lose some elasticity and therefore the ability to flex and expand with each heartbeat. The most widely accepted theory, when tinnitus occurs with hearing loss, is damage in the cochlea. Microscopic hairs form a fringe on the surface of each auditory cell (Outer Hair Cells-OHC and Inner Hair Cells-IHC).
Both the inner and outer hair cells are connected to the auditory nerve through the basilar membrane.
They are unable to hold their charge and leak random electrical impulses to the brain where it is interpreted as noise.
A comprehensive medical examination can rule out causative factors related to blood pressure, kidney function, drug intake, diet and allergies. Our Audiologists will perform an otoscopic examination of your ear canals to ensure there is no wax or debris buildup in the ear canals. We will assess your middle ear system to ensure your eardrums and attached middle ear bones are functioning appropriately. Individuals with mild tinnitus or longstanding tinnitus that is not life-affecting generally do not require intervention or treatment.
This improvement is not the result of physical changes, as damage to the auditory system that has been measured is typically permanent and irreversible. Tinnitus can be aggravated by excessive noise, nicotine, caffeine, tonic water that contains quinine, alcohol, and excessive doses of aspirin. Noise- induced hearing loss may occur by a one-time exposure to a loud sound or by repeated exposure to loud sounds over an extended period of time. In a quiet setting such as the bedroom at night, the use of a noise generator may be beneficial. If the tinnitus is accompanied by hearing loss, hearing aids are an effective way to deal with tinnitus. In fact, there has not been one scientific study to date that has shown long standing efficacy in the reduction of tinnitus with alternative approaches such as illustrated below. The sound is prevented from passing through the middle ear due to a blockage such as wax, a foreign object in the ear canal, infection in the middle ear or malformation of the pinna, ear canal or middle ear bones. Sensorineural hearing loss cannot be medically or surgically corrected therefore this damage is permanent. There is a problem with the outer and middle ear and damage to the cochlea or auditory nerve.
The possible effects of a hearing loss depends on degree of loss, early identification services, amplification, and parent involvement.
If loss is from birth, spoken language and speech may not develop spontaneously, or could be severely delayed unless modifications and interventions are taken. The child may rely on vision rather than hearing as the primary means for communication and learning.
Now, with newborn hearing screening, unilateral hearing loss is detected during the first months of life. Usually frequencies of 250-8000 Hz are used in testing because this range represents where normal conversation speech occures, although the human ear can detect pitches from 20-20,000 Hz.
We talk about noise induced hearing loss, common hearing loss myths, and what you need to know to stay healthy and protect your most valuable asset. Most of the individuals that seek help suffer from constant tinnitus-24 hours a day for seven days a week. Although tinnitus does not cause hearing loss, tinnitus can interfere with one's communicative ability. Tinnitus can also be extremely loud to the point where the individual may hear nothing else. The severity of tinnitus is related directly to an individual's reaction to, and perception of the tinnitus. Pawel Jastreboff estimates that approximately 17% of the world's population suffers from tinnitus which causes significant suffering in 4% of the general population. It is estimated that 10 to 15% of adults have prolonged tinnitus and seek medical intervention (Heller, 2003). Less common causes include a non-malignant tumour on the vestibular nerve (vestibular schwannoma), a fixation of the middle ear bones, or other relatively rare medical conditions. This causes the blood flow to become more forceful and turbulent, making it easier for the ear to detect heart beats.
Depending upon the movement of the cochlear fluids from sound stimulation, different hair fibers are put into motion. The nerves that carry impulses to the brain are adjacent to the base of the hair cells but are not quite embedded into the basilar membrane.
Unfortunately, the cause of tinnitus cannot often be identified, so, in some cases, the tinnitus itself may need to be treated.


We will need a complete list of current and past medications and an in-depth description of the tinnitus, including when it happens, and what seems to make it worse. Otoacoustic emissions testing will be done to assess the integrity of the cochlea (assess outer hair cell function) as damage to the cochlea typically can be detected before hearing loss is found with conventional testing. Nicotine and caffeine constrict the blood vessels which increases the speed of blood flow through the veins and arteries. A conductive hearing loss is usually correctable through medical management such as surgery, medication, or removal of the obstruction. Proper amplification and intervention should enable the child to hear and recognize most sounds. With early and consistent use of hearing aids, many children will be able to detect sounds such as speech.
Speech and oral language will not develop spontaneously without modifications and intervention. We also discuss vertigo, motion sickness, how to calculate your noise exposure risk, hearing loss rehabilitation, adult stem cell transplant hearing loss, and other alternatives to hearing aids.
Other forms of sound are described as hissing, roaring, pulsing, whooshing, chirping, whistling, rushing, booming, and clicking have also been described by individuals that suffer from tinnitus. Until recently, tinnitus has not received sufficient attention, either in clinical practice or in research. Studies have shown that tinnitus is more prevalent in females than males under the age of 50. Tinnitus may result from age-related hearing loss (presbycusis typically begins after the age of 55), ear injury, or a physiological condition.
High blood pressure, including hypertension and factors that increase blood pressure such as stress, alcohol, and caffeine, may make tinnitus more noticeable. Many researchers believe that when the structure of the hair cell collapses, random stimulation of the auditory pathways occurs. The movements of these hairs cause the auditory cell to discharge electricity to the auditory nerve, which is connected to the auditory center of the brain.
90% of the nerves derive from the inner hair cells (despite the fact that they are smaller in number). Alcohol increases the force of blood by dilating the blood vessels which causes greater blood flow, especially in the inner ear area.
The effects of loud noises may exacerbate tinnitus in addition to further damaging hearing.
The noise generator creates a soothing surf, waterfall or rainfall sound that should be used at a level slightly below the level of the tinnitus.
Auditory re-training uses sound generators that are set to a level that is below the intensity of the tinnitus (just audible and not masking the tinnitus).
The child is at risk for significant delays in spoken language speech understanding, language comprehension and voice quality. Spoken language is significantly delayed, abnormal speech patterns may develop and voice quality is usually diminished.
The brain translates these electrical impulses into sounds which we recognize and understand. Each inner hair cell has approximately 10 nerve endings attached to it which results in approximately 30,000 nerve fibers that transmit the electrical equivalents of the sound waves to the brain.
When used for an extended period of time, it induces subconscious habituation so that the tinnitus is not perceived as an intrusive or disturbing presence. While individuals may enjoy these sounds in nature, they are certainly more bothersome when they are coming from one's own ears or head.
Pawel Jastreboff estimates that 40% of individuals that suffer from tinnitus, have accompanying hyperacusis.
Until recently, tinnitus did not receive sufficient attention, either in clinical practice or in research. Narrowing of the carotid artery or jugular vein can result in turbulent blood flow and head noises. The stressful nature of some occupations can contribute to tinnitus, increase the severity of existing tinnitus, increase the individual's reaction to the severity of tinnitus, and hinder coping mechanisms. May have difficulty understanding spoken conversations coming from the side of the head that has the hearing loss. While the perception of tinnitus is very real, there is no external sound corresponding to the patients' perception of sound; thus, tinnitus can be classified as a phantom auditory perception. Malformation of capillaries, also called arteriovenous malformations, can occur in the connections between arteries and veins which can result in head noise. Our Audiologists will be happy to discuss the most appropriate custom protection for the noise levels to which you are exposed. Tinnitus may accompany a number of other symptoms such as a feeling of pressure in the ears, unsteadiness, and dizziness.
