Wearing hearing aids has been such a positive experience for Marie Redfern, she wants to encourage others with hearing loss to try them, too. Your experience can provide helpful information to someone looking for a great hearing care provider, reward a clinic for taking good care of their patients and create a sense of community where you live. Did you make a New Year’s resolution to finally have your hearing evaluated by a professional? It could be a noisy workplace, the constant drumbeat produced by MP3 players and other digital music players or the constant drone of traffic right outside the window. Noise induced hearing loss, the only type of hearing loss is fully preventable, is on the rise and is seen in younger generations.
There are many ways to prevent noise induced hearing loss such as turning down the volume and wearing hearing protection while around loud noise such as power tools and concerts.
People with diabetes are more susceptible to hearing loss, as well as people with cardiovascular conditions or heart disease.
Always read the warning labels on any meds you buy over the counter and ask your doctor about the side effects of any prescription medications you take.
However, we do know that damage to the hearing centers of the brain and damage to the delicate hearing mechanism that converts sound waves to electrical impulses lead to hearing loss – the permanent kind. See an audiologist or hearing aid practitioner – an expert in hearing, hearing loss and hearing solutions.
Then, working with you, the patient, these hearing professionals will offer a number of solutions from which to pick.
Your hearing professional will discuss with you the hearing test results and identify just how much hearing you’ve lost and in what sound frequencies that hearing loss has occurred. It is important to work one-on-one with a hearing professional to select the best hearing aids for you, your hearing loss and budget.
However, some hearing aid users don’t like the stuffy feeling CICs create so they cross that type off the list and not to mention CIC hearing aids are typically ideal for more mild hearing losses.
For those who want a more natural fit and feel, they opt for open-fit BTEs and RIC hearing aids. Open-fit BTEs and RIC hearing aids are also cosmetically appealing for those concerned about the cosmetics of wearing hearing aids. It’s the beginning of a new decade, the beginning of a new year and the beginning of new ears for you. There may be a natural tendency for dispensing professionals to recoil at the idea of a tuning fork test; it seems dusty and archaic in the face of all of our excellent electronic screening options.
Prior to the introduction of electronic audiological testing equipment, clinicians relied heavily on tuning fork tests (TFT) along with some other rudimentary tests, such as the “Whisper Voice.” Even with all of the electronic and computerized test equipment available today, TFTs play a critical role as an adjunct for clinicians to determine the type of hearing loss in patients. Although some of the TFTs have lost their value, two tests—the Weber and Rinne—have stood the test of time and are still important for clinicians in diagnosing hearing loss. Tonndorf and others10-12 have pointed out the important contribution that TFTs make for clinicians in developing their otologic diagnosis. Tonndorf and colleagues11,12 offered the most detailed and complete explanations of how bone conduction (BC) works.
1) Middle ear inertia, 2) Middle ear compliance, 3) Inner ear compression, and 4) Round window release. 5) Inner ear fluid inertia, 6) Oval window release, and 7) Release through the “third window” (cochlear aqueduct).
Tonndorf12 comments, “All three anatomical parts of the ear, the outer ear canal, the middle ear, and the inner ear, contribute independently to bone conduction [transmission].” He went on in a later paper11 to further clarify his theory of bone conduction. Tonndorf stated that 500 Hz and 1000 Hz are the frequencies that are most affected by middle ear inertia.10 With the Rinne test, at frequencies above 1000 Hz, the air-bone gap has to be larger in order to observe the fork being louder behind the ear compared to at the opening of the meatus. Clinically speaking, we know quite a lot about tuning fork tests; however, the mechanisms explaining the interaction of the components can be confusing. The Weber and Rinne should be administered at a BC level of 40 to 50 dB HTL (hearing threshold level) using a bone oscillator at 500 Hz or 1000 Hz.11 When a tuning fork or bone oscillator is overdriven and made so loud it deviates from its fundamental frequency, it will produce distortion.
It should be noted that it is common to use the term 512 Hz and 1024 Hz when referring to a tuning fork test.


In the Weber test, the tuning fork tines are set into vibration and the stem of the fork is pressed against the middle of the forehead. If a conductive, mixed, or sensorineural hearing loss is present in only one ear and the other ear is normal or has better sensorineural hearing, the patient will report hearing the fork in that ear with the conductive loss or the ear with greatest sensorineural loss. In administering tuning fork tests, we have found that patients have no difficulty reporting their observations to the clinician.
This paper was written with the intention of communicating to hearing care clinicians an explanation of two tuning fork tests, the Weber and Rinne. The Weber and Rinne can be administered and communicated in only a few minutes and can be valuable in assisting hearing care professionals in interpreting and verifying their own test results. In fact, by making a few lifestyle changes and getting fitted with a pair of today’s high-tech hearing aids, you can live the life you used to live and hear the richness of life the way it was meant to be heard.
If you are exposed to workplace noise, talk with your employer about providing you hearing protection.
Poor circulation of blood and oxygen can affect nearly every part of our bodies, including our inner ears which allow us to hear.
Some medications alone are not ototoxic; however, when taken at the same time with another drug they can become ototoxic. Smoking, lack of exercise and a diet lacking substantial nutrients can all contribute to hearing loss. These highly trained and certified professionals will perform a top-down hearing evaluation to determine the scope and degree of hearing loss you have.
In most cases, a pair of hearing aids will get you back in the game and keep you in play longer.
And although cost is typically a high priority, try not to make it your number one consideration. Together, your audiologist or hearing aid dispenser will develop a strategy that suits your hearing needs and personal preferences.
The design and cosmetic appeal coupled with outstanding sound quality and automated convenience are helping those with hearing loss hear the sweet sounds they have been missing.
However, two tuning fork tests—the Rinne and Weber—have stood the test of time and retain their importance for clinicians in diagnosing hearing loss. In this paper, we review the basic principles involved in the use, theory, and interpretation of the Rinne and the Weber. Michael Hall, AuD, is a clinical audiologist who lives in Walnut Creek, Calif, and is now retired from private practice. Although there are quite a few TFTs that were developed prior to the widespread use of audiometers, TFTs other than the Weber and Rinne are not of the same clinical value they were prior to the introduction of audiometers and immittance bridges.
He and other researchers did an excellent job explaining the rationale for 512 Hz and 1024 Hz as the preferred frequencies for administering the Weber and Rinne.
The rationale for using lower frequencies is that the tuning fork is more subtle in terms of identifying conductive hearing loss at these frequencies.
The factors that explain why the fork lateralizes to the ear with a conductive pathology when the other ear is normal or has some degree of sensorineural hearing loss are the same four primary factors previously noted for BC: middle ear inertia, middle ear compliance, inner ear compression, and round window release.
Technically, 500 Hz means a 500 Hz tone via the audiometer’s bone oscillator, while 512 Hz is the tuning fork frequency. A useful method of recording the results of TFT is shown in Figure 1 where the Latin origin of these letters is defined. If a conductive loss is present in only one ear and the other ear has a sensorineural loss, the patient will still report the fork being louder in the ear with the middle ear pathology. The tuning fork tines are put into vibration in the same manner as when conducting the Weber Test. Audiometric puretone and tuning fork test results for a patient with a unilateral mixed hearing loss. Audiometric puretone and tuning fork test results for a patient with a bilateral sensorineural hearing loss. These tests, in our opinion, offer support to more modern audiometric tests in assisting all professionals involved in administering hearing tests.


This may be useful, for example, in cases of conductive hearing loss with normal tympanograms where an air-bone gap is present on the audiogram, but the patient does not have otitis media.
Unfortunately, many of us recognize that we don’t hear as well as we did in years past but accept hearing loss as inevitable. Ensure you always manage your prescriptions at one pharmacy so the pharmacist can warn you on any potential side effects of multiple prescriptions. If they suspect an underlying medical condition contributing to your hearing loss, they will refer you to yoru family physician or an Otolaryngologist - a physician specialing in ears and hearing. This results in a comfortable and more natural feeling hearing aid in regards to both sound and physical feel. Thank you to miniaturization of digital hearing aid parts and new innovative designs, today’s BTEs are not the type grandpa used to wear. No longer are they beige and boring, they’re fashion statements that also improve your hearing. We will also provide a discussion of how to interpret the results, as well as the AC and BC phenomenon that determines the various results seen with these two tests. Carl Croutch, AuD, is an audiologist at Kaiser Permanente Hearing Center in Daly City, Calif. For example, at frequencies 2 to 3 octaves lower than 2000 Hz, an air-bone gap one-half or less the size than at 2000 Hz is typically needed to indicate a conductive loss.
The effect of all of these various components results in producing in-phase and out-of-phase traveling waves in the cochlea.11 The in-phase condition results in an increase in amplitude, which creates a perception that the Weber is louder in the ear with the middle ear pathology. The stem is placed on the mastoid prominence on one side, and then transferred to the opening of the same ear while keeping the tuning fork from actually touching the patient’s ear.
Looking at Figure 1 will acquaint the reader to a quick and easy method to report TFT results. When conducting the Rinne, where there is a 30 dB or more difference between ears, it is advised to mask the better ear when conducting the test.
In fact according to the National Institute of Deafness and Other Communication Disorders, 1 in 3 Americans over the age of 65 have some degree of hearing loss.
And notify ALL your doctors about ALL of your prescriptions – especially ones prescribed by a different physician. In fact, medics in war zones now carry medications that are administered to soldiers who are exposed to loud, concussive explosions. When middle ear pathologies are present, there is an increase in impedance at the footplate and oval window, which create in- and out-of-phase traveling waves in the cochlea.
When the middle ears are normal, the Weber lateralizes to the better cochlea simply because it is the better-hearing ear. Normally, we instruct the patient that they will hear two sounds: one at the bone behind their ear and the other in their ear.
If the patient’s hearing loss is severe, the clinician may rely on sign signals such as having the patient hold up one or two fingers to indicate which sound is the loudest. The sooner these meds are given after exposure to an explosion, the more likely hearing returns to the normal range, though there’s no hard and fast rule. Today’s hearing aids come in a range of styles, types, colors and profiles, one of which is sure to suit your needs and preferences.
The patient will report they either cannot tell if it is louder in one ear or the other, or will report hearing it at their forehead. They are cautioned not to think about what the correct answer should be, but to merely say whether number 1 (mastoid prominence) or number 2 (the opening of the ear) is louder. However, in a severe loss with no conductive component present, it is unlikely the tuning fork will be heard.
