EAR HEALTH
EN
Our ability to hear is amazing. Treat your ears like the precious tools they are, and they
will continue to provide you with exceptional data, as well as a lifetime of incredible
sonic experiences.
In general, do not listen “too loud” or for “too long,” and be attentive to your own ears.
Ringing, discomfort, or sensitivity to high frequencies and treble may be a signal from
your ears that you are pushing them to their limits and causing irreparable damage.
As a general practice, find what seems to be your preferred listening level and then
adjust the volume down another 10% or more. Surprisingly, your ears will attune to a
slightly lower volume over time, and what seems quiet at first can be perfect for longer
listening periods.
NIHL
NIHL is a preventable condition caused by both one-time and extended exposure to
excessive decibel (dB) levels. This harm to sensitive inner ear structures is irreversible
and people of all ages can be affected. Damage can happen in a single event or
gradually over time. One-time exposure to an intense “impulse” sound, such as an
explosion, or by continued exposure to loud sounds over 85 decibels can cause harm.
Indicators of NIHL include hearing loss and tinnitus, a condition of sensing constant
ringing, buzzing, or roaring. The NIDCD (National Institute on Deafness and Other
Communication Disorders) offers this simple rule of thumb: avoid sound exposure that
is “too loud, too close, or too long.” Here are some general references to sound
levels that occur in everyday life: refrigerator humming (45 dB); normal conversation
(60 dB); city traffic (85 dB); motorcycles (95 dB); an MP3 player at full volume (105 dB);
sirens (120 dB); firecrackers (150 dB).
