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).
NIHL (NOISE-INDUCED HEARING LOSS)
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.
