Results from this study suggest that, when trying to extend the fitting range of RITA BTEs into the low frequencies, closed domes—and to a lesser extent double domes—are not very effective. An acoustic comparison of the most popular RITA BTE couplers is offered.

Hard-of-hearing musicians have special needs that are not always met by hearing aid technology. This article illustrates how clinical choices, state-of-the-art digital signal processor (DSP) systems, and advanced DSP software engineering improved the music listening experience for three musicians. A continuation from HR’s special issues in February and March on Musicians and Hearing Aid Design co-edited by Marshall Chasin, AuD, and Larry Revit, MS.

A look at a new extended-wear, deep-canal, disposable device, offering 24/7 listening capabilities and 100% invisibility relative to cosmetics. InSound Medical’s Lyric is designed to provide solutions to many of the drawbacks encountered with traditional hearing aids, with significant acoustic, practical, and cosmetic benefits.

Bone conduction tests are performed on a routine basis within dispensing offices. This article describes a phenomenon called pseudosensorineural hearing loss caused by a loading effect on the middle ear and reviews previous literature that describes this effect.

A discussion about interaural time differences (ITDs), interaural level differences (ILDs), and spectral peaks and notches, and how these elements influence speech understanding in difficult listening environments.

Hearing aids are now offering larger bandwidths, with extended frequencies out to 10,000 Hz. It is expected that qualitative and quantitative improvements in quiet and in noise with respect to speech, music, and spatial cues will be realized—leading to better speech understanding, listening enjoyment, and customer satisfaction.

About one-fifth of the workforce between the ages of 17 and 25 years entering industries already have notches consistent with noise exposure. This literature review, in the form of a sound-exposure diary of a hypothetical high-school graduate waiting to enter college, along with relevant research findings, sheds some light on why.
