Physicians Urge Parents To Preset Volume On Holiday
Electronics
Editor: I'm hoping everyone is already aware of the dangers of loud
electronics to a person's hearing, but it can't hurt to have another
reminder. The folks at Vanderbilt University have issued this statement
for the 2009 holiday season.

Parents and children giving or receiving an electronic device with
music this holiday season should give their ears a gift as well by
presetting the maximum decibel level to somewhere between one-half and
two-thirds maximum volume, according to experts at Vanderbilt University
Medical Center.
Any sound over 85 decibels (dBs) exceeds what hearing experts consider
to be a safe level, and some MP3 players are programmed to reach levels as
high as 120 dBs at their maximum, they say. (this is equivalent to a jet
airplane taking off or landing).
Vanderbilt Bill Wilkerson Center Director Ron Eavey, MD, who also
chairs the Department of Otolaryngology, says the new generation is
especially susceptible to hearing loss when they listen to music with
headphones or earbuds either too long or too loud.
One preventive measure is to preset the device so that it cannot be
turned up to damaging levels.
"As parents, we can't hear how loud their music is when they have the
earbuds in so this is an important step," Eavey said in a statement from
the university. "I can tell you that if you hear the music coming from
their headphones it is too loud, but an easier way to know for sure is to
preset the device.
"This will still allow them to listen to and enjoy their music but will
safeguard against ear-damaging volume levels," he added.
Eavey said the problem stems from the fact that our brains love music
and inherently want the volume turned up, but our ears can't always handle
that volume adjustment.
"If you are walking down the street listening to your MP3 player and
there is a jackhammer across the street, most people will turn up their
MP3 player to drown out the jackhammer," he said.
Anne Marie Tharpe, professor and chair of Hearing and Speech Sciences,
says that noise-induced hearing loss is often not obvious right away,
especially with young children.
"The symptoms can initially be subtle and include difficulty hearing
when there is background noise," she said in the statement. "Such losses
can result in significant challenges for children in classroom settings."
It is also important to remember that higher resolution music downloads
will allow for better sound at low volume levels.
Music with little detail, or lower resolution, will play at a lower
quality.
