Does Digital Delay in Hearing Aids Matter?
Does digital delay in hearing aids contribute to a significant degradation in the understanding of speech or the appreciation of music?

An insightful study of environmental noise and its potential impacts on health.
In preparation for a book that will be (hopefully) published in the spring of 2022 called “Music and Hearing Aids” (Plural Publishing, working title), I conducted a literature review of previous research regarding the programming of hearing aids for music.
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.

Read MoreThis 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.
Read MoreAre 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.
Read MoreRecently 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.
Read MoreIt 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.
Read MoreI 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?”
Read MoreIt 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.
Read MoreAs 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.
Read MoreThe 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.
Read MoreVerification of a hearing aid (or hearing protection) fitting is an obvious usage, but it can be quite instructive about some general acoustic principles.
Read MoreSince the beginning of my audiology career I have heard many of my hard-of-hearing patients comment that at around 3 PM they hit the wall and need a nap.
Read MoreWell so much for Audiology 101. This also brings up an interesting potential explanation about why some people don’t like to use noise-canceling headphones.
Read MorePerhaps the most well-read article of 2017 is “The effects of service-delivery model and purchase price on hearing-aid outcomes in older adults: a randomized double-blinded placebo-controlled clinical trial” by Larry Humes and his colleagues at Indiana State University, published in the March 2017 edition of the American Journal of Audiology. Drs Marshall Chasin and Steve Aiken provide their perspectives on this important research.
