EARPHONE USE CAN DAMAGE YOUR EARS

DO YOU KNOW? EARPHONE USE CAN DAMAGE YOUR EARS.

Of late, people are becoming deaf earlier than our ancestors. Studies show that the exposure to noise pollution could be the main culprit. Modernization and technological advancement has contributed markedly to the increase in ambient noise levels. Prolonged use of earphones to listen to music is on the increase, mainly among the young. If the same is not used diligently it will lead to the permanent Hearing Loss.

It is very important to remember that many devices often have a sound output reaching 110dB and hence is powerful enough to cause Noise Induced Hearing Loss with a single exposure.

  • The louder the noise the shorter is the safe exposure time.
  • The upper limit of safe daily exposure is slated for 85dB sound is 8 hours.
  • Generally the safe amount exposure time is reduced by a factor 2 for every additional 3 dB.
  • The safe exposure at 91 dB is only 2 hours [National Institute of Occupational Safety and Health, 1998].

SOUND HEARING LEVELS:

A simple way to define safe volume is to use the Earphone at a volume “which enables the wearer to hear normal conversational voice with the head set on”. Even at this volume, continuous listening though the ear phone should be restricted to an hour followed by a rest period of 2 hours.

In addition to its effects on hearing, noise pollution also causes Non hearing Effects like:

  1.    Physical changes – Poor Concentration, Fatigue, Stress reaction. Exhaustion.
  2.    Verbal communication – Interferes with speech communication.
  3.    Sleep disturbances.
  4.    Cardiovascular Effects – Risk of hypertension / IHD.
  5.    Mental Health Effects – Neurosis, Irritability, Anxiety, Emotional stress, Mood changes, Memory deficit.
  6.   Poor Performance – In school, work place.
  7.   Change in Behavior – Annoyance, Anger, Disappointment, Depression.

Let me finally conclude by saying the “Precaution is much better than Cure”. Hearing Loss is something which can be avoided
