What to Tell Audio Engineers About Equalizations for Their Hearing Loss
For audio engineers and musicians who have high-frequency hearing loss, it's not enough to simply boost frequencies to match their audiogram.

Back to Basics: My Favorite Frequency
Once hearing aid fitting targets are met, an increase in gain and output in the 1500 Hz region will add a sense of “warmth” to the fitting.

What Is the Best Musical Instrument for My Hard-of-Hearing Child?
From time to time, I am asked about the best musical instrument for someone’s child who is hard of hearing. If this were the 1960s, I may have said drums. However, today that 60-year-old answer would be quite simplistic given the advancement of knowledge (and politics) surrounding hearing loss and hearing aid/cochlear implant technology.
Measuring Peak Noise Exposure…While Outrunning the Cops
The peak sound pressure really has no value in the estimation of the sound exposure dose whether this is music, industrial noise, or recreational noise.

Modification of Musicians’ Earplugs
Marshall Chasin explains how earplugs are modified for long-eared or short-eared individuals who have ear canal resonances that are less, or more, than the usual 2700 Hz.

Asymptotic Hearing Loss: When Is a Metaphor Just a Metaphor?
Like all healthcare fields where the clinician needs to explain complex concepts to the lay public, metaphors are used. In the optical field, “nearsighted” and “farsighted” are actually good metaphors despite their simplicity and academic inaccuracy. In the field of audiology, we have the description of the audiogram with the piano keyboard across the top; a good explanation, but limited in that it’s only the right hand side of the keyboard and musical notes are not pure-tones.

Testing for Cochlear Dead Regions Using a Piano
Audiologist Marshall Chasin posits a simple test that can be employed with a piano or keyboard that might quickly screen people for the possibility of a cochlear dead zone.

What Do Acoustics, Paris Hilton, and Shower Curtains Have in Common?
The Bernoulli effect is central to how we speak and it, at least in part, defines many of the characteristics of the speech spectrum input to hearing aids.

Custom Earmolds and Plugs: A Formula of Area Over Love
This may sound like a cheap romantic novel or a new soap opera but “area over love” is an important acoustic principle that rears its romantic head in a number of clinical scenarios that are encountered, almost every day.

Are Polaroids Needed All Over Again?
Are we now at the point where audio files—whether they are MP3, WAV, or any other format—would come under suspicion of being altered and, therefore, not of any great forensic use? In his “Back to Basics” column, Marshall Chasin, AuD, explains why this may be so.

Using Audiology To Extend a Musician’s Career
Recently there have been news reports about famous musicians who can no longer perform their music and have chosen to retire. “By hook or by crook, that should not happen,” says Marshall Chasin, AuD.

What Do Spondees and Music (and Math) Have In Common?
It is almost as if music has something in common with everything: psychology, physiology, acoustics, engineering, most areas of the arts, and now, the lowly spondee.

A Vocalist Wants a Quiet Space at Home to Practice
I receive many questions from instrumental musicians, vocalists, and performing artists about issues relating to how they should practice. A particularly common question is “How can I modify a room in my house so that my vocal practice doesn’t drive my dog crazy?”

These Hearing Aids Make Everything Sound Digital!
It is conceivable that the modern digitization process reduces the extraneous hearing aid (microphone) noise too much and a clinical strategy would be to reprogram the hearing aid with minimal expansion implemented in the hearing aid software.

Changes in Thinking About TTS: Pre- and Post-2000
As the name suggests, temporary threshold shift (TTS) is a temporary loss in sensitivity to certain sounds following an exposure to a loud noise or music. Marshall Chasin, AuD, explains how our thinking about TTS has changed over the years.

A Cold-Weather Experiment
The issue is that in perception we rarely need to hear the exact frequency (or frequency spectrum) of speech or of music. However, we do need to hear the relative differences in spectral cues.

Real-Ear Measurement is Not Just for Verification
Verification of a hearing aid (or hearing protection) fitting is an obvious usage, but it can be quite instructive about some general acoustic principles.
