Page Content 1One of Liverpool’s leading tinnitus experts is backing a national campaign to raise awareness of the condition, which affects millions of people. El Segundo, Manhattan Beach, Hermosa Beach, West Hollywood, Mar Vista, Venice CA, Rancho Palos Verdes and the surrounding area.
Tinnitus is an abnormal perception of a sound, which is reported by patients as being unrelated to an external source of stimulation.
Objective tinnitus - This is a noise perceived by the patient as well as by another listener.
Because the function of the auditory (hearing) nerve is to carry sound, when it is irritated from any cause, it produces head noise.
Peripheral site lesion - One located on the auditory nerve or cochlea, and includes dysfunction established within the auditory system that extends up to, but not involving, the brainstem. Central site of lesion - This refers to involvement of the central auditory pathways, beginning at the brainstem and involving other portions of the central nervous system. This is demonstrated by patients who have had unyielding tinnitus after having surgery on their ear or incurring severe diseases of the ear. Abnormal neural activity - Tinnitus could be explained by abnormal neural activity in the auditory nerve fibers, which may occur if there is a partial breakdown of the myelin covering of individual fibers. Chronic cochlear disorders - There may be increased spontaneous activity in the hair cells and neurons, resulting in tinnitus. Medications - There are some drugs which will cause tinnitus, such as excessive aspirin intake. Tumors - On the hearing nerve or other problems in the brainstem or central nervous system.
A complete cochleovestibular evaluation is necessary in all patients with severe, disabling tinnitus. The audiologist will attempt to do pitch-matching and loudness-matching when other forms of diagnostic tests fail. Listening to a fan or radio - This generally is more advantageous if one is attempting to go to sleep.
A tinnitus masker - This device is a small electronic instrument built into a hearing aid case. Avoidance - This includes making every attempt to avoid anxiety, as anxiety increases tinnitus. It is TINNITUS – a perceived ringing or buzzing in the ear when no actual sound exists. What causes tinnitus?  While we can’t always determine the cause of tinnitus in every patient, we know that tinnitus is a symptom, not a disease itself.  It can be caused by disorders of the middle or inner ear, foreign objects or wax in the ear, or exposure to loud sounds.

In the absence of these more severe symptoms, a good place to start is with an audiologist.  All audiologists should have received some exposure to tinnitus theory in their training. The important thing to remember is that if tinnitus is interfering with your quality of life, there is help available from specialists right here in the Treasure Valley.

Tinnitus affects about 10% of the population and causes people to hear a noise in their ears or head without an external source.
It may occur with a hearing loss, vertigo, or pressure symptoms in the ear or it may occur alone. The auditory system involves highly complicated inner ear structures, many nerve pathways, and a great amount of nuclei that form a complex neural network. There are two different kinds of afferent fibers in the auditory nerve: inner hair cell fibers with large diameters and outer hair cells fibers with small diameters.
If you have tinnitus and are on medication, you should discuss the symptom of tinnitus with your physician. The test battery used is an attempt to establish the site of lesion and to rule out any significant pathology which may require further treatment.
Since tinnitus is often high pitched, frequency judgments in this region normally are poor. In addition, an attempt may be made to determine the maskability of the tinnitus, which is unrelated to its loudness. It consists of exercises the patient learns in order to control various parts of the body and relax the muscles. A person with tinnitus should avoid losing sleep and becoming fatigued, because, generally, patients who are tired seem to notice their tinnitus more. Miller currently serves on the national audiology advisory council for the American Speech-Language-Hearing Association, and is active at the local, national, and international levels in the Special Olympics Healthy Hearing program. 31, 2012 The Texas Biomedical Device Center at UT Dallas has agreed to partner with neuroscience-based medical device company MicroTransponder to conduct one of the first U.S. Tony Kay, Head of Audiology Services at Aintree (pictured above), said: “Tinnitus affects people of any age and can sometimes lead to stress and anxiety and also impact on sleep patterns and concentration. With tinnitus, the reported distress is usually subjective and difficult to record and appreciate by others. This condition must always be thought of as a symptom and not a disease, just as pain in the arm or leg is a symptom and not a disease. When the tinnitus is persistent, this indicates that the site of lesion causing the tinnitus likely shifted into the central nervous system.

Thus, loss of signals from the cochlea might trigger tinnitus as a manifestation of a functional imbalance between the two sets of fibers.
Frequency discrimination up to approximately 16,000 Hz (in the upper limit of hearing) is far less exacting than the middle-frequency region. The masker is based on the principle that most individuals with tinnitus can better tolerate outside noise than they can their own inner head noise. Also, the use of nerve stimulants is to be avoided, as excessive amounts of coffee and smoking contribute to the head noise.
Each patient has an individual response to medication, and what works for one patient will not always work for others.
While the majority of patients cannot be cured of their tinnitus, there are some very effective management techniques. Tinnitus will not cause you to go deaf, and statistically, 50 percent of patients may express that their tinnitus decreases or is hardly perceptible as time passes. In addition, patients suffering from high-pitched tinnitus often have a high-frequency hearing loss, which may impair frequency discrimination.
Some of these medications have been proven, however, to decrease the intensity of the tinnitus and make it much less noticeable to the patient. He has been on the faculty of three universities and has owned private practices in Oklahoma City and Dallas. Therefore, test-retest reliability in matching the frequencies of audiometer tones to the pitch of tinnitus may be poor.
The focus will be on tinnitus research, with a presentation from one of the research team from the Nottingham Hearing Biomedical Research Unit.
Tinnitus causes mild irritation for some people, but is severely disabling for many others.
There’s no pressure to stand up and talk in front of the group but patients tell us that it’s reassuring to know they are not alone with their tinnitus.
