Hearing Health & Technology Matters
Music to your ears:
hearing aids, music,
and musicians
Edited by Marshall Chasin, AuD
The new e-Book series from Hearing Health & Technology Matters, LLC, organizes topics
culled from the thousands of articles at HearingHealthMatters.org. The books have two
purposes:
1) To allow our readers easy access to all relevant content written about a specific topic;
2) To archive our Internet content for future access.
The first e-book in the series is “The Big Fat PSAP Book,” which debuts in the midst of
intense social policy discussion about hearing device availability in the US. It is a large
book, reflecting the depth and degree of discussion among many stakeholders in the
debate.
The second e-book in the series is “HearUSA,” is a shorter book that details one colorful
and fascinating path taken in the history of hearing aids in the US. It debuted in July, 2016.
E-books are available for purchase on the HHTM homepage. If you enjoy these e-books,
please look for others on selected topics which will join the series e-Books as we have time
to put them together. In the process, we welcome suggestions for categories and topics
from our readers.

Prelude and Introduction:
Music to your ears is an overview of those features that touch upon the care and feeding of
musicians, or those, like me who are less talented and who just like to listen to music.
Contributions have been made by a group of dedicated people with the goal of improving
listenability and safe listening. This may be for hard of hearing children who are about to
select their first musical instruments, or about a 20s something rockers who need to
understand the more subtle points in choosing hearing protection or in-ear monitors.
This book has nine sections and can be read in any order, with as many items in each
section as the reader wants to use. It can be used as a supplement in any university or
college course on noise control, or even as part of a music program. Or it could be read
with a cup of tea while having one’s feet propped up against the cushions in front of a
roaring fire (or air conditioner in summer).
Each section of the book has a number of posts, all written with the reader in mind, and
balancing scientific fact, humor, and clinical gems making this a very readable and
smoothly flowing book.
The nine sections are:
1. Music and hearing loss
2. The acoustics of music
3. Room acoustics and reverberation effects
4. Hearing aids and music
5. In-ear monitors
6. Musicians’ hearing protection
7. Consumer issues
8. Some notable notables
9. Encore i Finale
Like most areas of study, the scientific principles can be used in other, seemingly unrelated
areas. While this is a book about music, musical instrument and its effects, the acoustic
principles can be applied to the human vocal tract, the acoustics of a classroom, and even
the design of a concert hall. And many of the technologies can extend beyond the musician
or listening to music, to populations such as the military, and those suffering from post-
concussion syndrome.
Finally I would like to thank the other editors of HearingHealthMatters for their support
and encouragement during the writing and editing process.
