It is common knowledge that shows loud and headphones can be hazardous to your hearing. But to fully protect the ears is also to be aware of small sound sources in daily life, suggest researchers at the University of Cincinnati (UC), the United States.

Speech at UC recommend taking measures regarding the use of headphones and headsets to answer the phone high.

Stephanie Lockhart, audiologist, advises using the "rule of volume 1 / 2" for personal listening devices, or keep the volume up to half the level available. It also recommends short breaks or device to give ears a rest.

Unless the headphones are "anti-noise, you should be able to hear someone three feet away."

Lockhart also recommends hearing conscious. "Some toys with sirens, etc., can emit sounds of up to 90 decibels," she says. "Listen to them before buying them and purchase toys with volume control."

Although technology has provided many ways to improve hearing loss, your hearing is a natural limited resource, says Lockhart.

The loud noise could expose the inner ear hair cell damage. Damage resulting from this noise, short and intense, can be cumulative and become regular after exposure to loud sounds over time.
