Exploring the Statistics of Hearing Loss in Veterans

Hearing loss is a significant health issue among veterans, and its impact is often underestimated. According to recent studies, hearing loss affects approximately 60% of veterans who served in Iraq or Afghanistan, while around 25% of all veterans report hearing problems. These numbers are alarming, but what is behind these statistics? Let’s dive deeper and

Classroom Sound-Field Systems

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 system view them as one

Hearing Aid Services and Satisfaction: The Consumer Viewpoint

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

The Audiogram: Explanation and Significance

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,

Feedback Cancellation Systems and Open-Ear Hearing Aid Fitting

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

Some Reflections on Digital Signal Processing (DSP) Hearing Aids

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 be an economical

MULTICHANNEL AND MULTI-MICROPHONE DIRECTIONAL HEARING AIDS: Fitting Procedures and Evaluation of Current and Emergent Technology

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

Dr. Ross on Hearing Loss Noise Reduction Hearing Aids: Why They’re Needed, and How They Work

Some years ago on a visit to New York, my family and I decided to have brunch at one of the “in” places in Greenwich Village. As we entered, we were greeted by the happy chatter of other diners. While these sounds would be a problem for me, it was an expected one and one

Evaluating the Performance of a Hearing Aid in the Real-Ear

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 in
