When the topic of assistive listening devices arises, the lowly telecoil hardly enters into the discussion. Yet the ordinary telecoil (the "T"coil) is perhaps the most common and most underestimated assistive listening device available for hearing-impaired individuals today. They are inexpensive, simple to operate (if one knows how), and can be incorporated in body worn, … [Read more...] about TELECOIL AND TELEPHONES

Much has been written about classroom sound-field amplification systems since they were first introduced about twenty years ago. As their potential contribution to children in classrooms becomes increasingly clear, there now appears to be a developing professional consensus regarding their efficacy. Indeed, those professionals who use and/or evaluate classroom sound-field … [Read more...] about Classroom Sound-Field Systems

This article first appeared in Hearing Loss (Jan/Feb 2005) It's undeniable that the price of hearing aids is often a source of contention between consumers and their hearing aid providers. Nobody likes to be told that they're going to have to lay out six or more thousand dollars for anything. But there are also some points that I think we can all agree on. Perhaps, it would be … [Read more...] about Why do Hearing Aids Cost So Much?

I've worn hearing aids for over 45 years and I've been an Audiologist almost as long. I've worked with hard of hearing and deaf people and their families for my entire career and you would think that I would have a good understanding of the feelings and experiences of people who are deaf, particularly late deafened people. Well, I thought I did; certainly I felt that in my work … [Read more...] about My “Near Deaf” Experience

introduction In the U.S. today, a person can purchase hearing aids from two types of dispensers: Audiologists and Hearing Instrument Specialists (formally known as hearing aid dealers). Both groups are licensed to dispense hearing aids, but come to this activity based on significantly different paths of formal education and training.  There is no information that indicates … [Read more...] about Hearing Aid Services and Satisfaction: The Consumer Viewpoint

Recently, I’ve been trying to organize some of the columns and articles I’ve written over the past ten years. As I was looking through them, it became apparent that I’ve neglected to discuss what is perhaps most important hearing dimension of all, the simple audiogram. In reality, however, the “simple” audiogram, and particularly its implications, is not quite so simple. Even … [Read more...] about The Audiogram: Explanation and Significance

The presence, or threat, of acoustic feedback has long been one of the major problems in the fitting and wearing of hearing aids. Acoustic feedback occurs when some of the amplified sound leaks from the ear canal and is picked up by the hearing aid microphone and then re-amplified. This starts the cycle of leakage and re-amplification (the "feedback loop") that results in the … [Read more...] about Feedback Cancellation Systems and Open-Ear Hearing Aid Fitting

So-called digital hearing aids are an outgrowth of the computer revolution that is transforming our entire society. Today, digital technology has been applied to hearing aids in two distinct formats: Digitally programmable analog signal-processing (ASP) instruments and digitally programmable digital signal processing (DSP) Digital encoding in the latter technology is proving to … [Read more...] about Some Reflections on Digital Signal Processing (DSP) Hearing Aids

If you are an adult and have just received your first hearing aid, the chances are that its need has been apparent to most everyone, except perhaps yourself, for years. The average adult receives his or her first hearing aid some five to seven years after the problems caused by a hearing loss are first noticeable. Up to that point, because the usual onset of an adult hearing … [Read more...] about Helpful Hints to the New Hearing Aid User

The only sound dimension that was “adaptive”  with my first hearing aid was the loudness. I could choose to turn the volume control up or down, and that was it.  True, the aid also contained an accessible tone control with three choices (normal, high-tone, and low-tone), but for the most part, I (and most hearing aid users) left that one alone. Evidently, I was one of those … [Read more...] about Environmentally Adaptive Hearing Aids

The most common complaint of those who wear hearing aids, by far, is interference from background noise and reverberation (e.g. echoing environments). The RERC for Hearing Enhancement has been working on techniques for reducing the effects of background noise and reverberation on speech clarity. Thus far, improvements shown with single microphone input are small, if any. … [Read more...] about MULTICHANNEL AND MULTI-MICROPHONE DIRECTIONAL HEARING AIDS: Fitting Procedures and Evaluation of Current and Emergent Technology

The most frequent complaint by people who wear hearing aids concerns their difficulties in tolerating background sounds. Noise is the enemy of the hearing aid user; it affects not only speech comprehension, but the very willingness to wear hearing aids. One of the first comments often made by new hearing aid users relates to the high, and disturbing, levels of noise they can … [Read more...] about Acceptable Noise Levels (ANL)

Years ago, the usual audiometry session consisted of pure-tone threshold testing across frequency (the audiogram) and, for a “comprehensive” examination, it included a test of word intelligibility under quiet conditions. Compared to that period, we now have a plethora of tests to evaluate a person’s auditory status. Diagnostic hearing tests can identify abnormalities anywhere … [Read more...] about Evaluating the Performance of a Hearing Aid in the Real-Ear

The topic of tinnitus often arose during my days as a teacher and clinical audiologist. For the most part, my responses simply regurgitated the conventional wisdom of the time, i.e., that tinnitus was a common problem, of unknown and varied origin, and that there were no sure-fire cures for the condition. Basically, I sloughed the topic off, primarily because there really … [Read more...] about Developments in Tinnitus

In considering the personal and social identity of hard of hearing people, in the very fact that such an issue is framed for discussion, we clearly mean to contrast our situation to that of people who are physiologically deaf, or who consider themselves socially and culturally Deaf in spite of the existence of significant amounts of residual hearing. But even though it is … [Read more...] about Personal and Social Identity of Hard of Hearing People

Judging from the most recent edition of Audiology Today (May/June 2004), the issue of OTC hearing aids is still roiling the hearing aid industry, particularly the dispensing community.

In the Beginning By all accounts, the audiology profession had its genesis in WW II, as an outgrowth of the aural rehabilitation (A/R) programs provided for servicemen who lost hearing in the war. What the government did was bring together a variety of specialists, told them to organize an A/R program, and essentially give them a blank check. The result was the kind of … [Read more...] about A Retrospective Look at the Future of Aural Rehabilitation

The profession of audiology has its roots in the aural rehabilitation (A/R) programs organized by the US military during WW II. Their purpose was to respond to the needs of servicemen who lost hearing as a result of war service. The medical authorities brought together a number of specialists and asked them to create an optimal A/R program. With little financial restrictions … [Read more...] about Home-based Auditory and Speechreading Training

Auditory training can be defined as formal listening activities whose goal is to optimize the activity of speech perception (Dr. Arthur Boothroyd).   It is based on an assumption that listeners often need help in dealing with the speech perception deficits that remain after auditory function has been optimized through an appropriate hearing aid selection process.  This point … [Read more...] about Dr. Ross on Hearing Loss

The Marketing of Digital Hearing Aids Over the past 50 years that I can personally recall, there have been ambitious and hyperbolic marketing appeals about new developments in hearing aids.

My first exposure to music while using my cochlear implant (CI) occurred when I left the NYU Center, right after the implant was activated.  It was a cold day in January and I was lucky to find a cab right outside the Center to take me across town.
