Can you hear me? Or is your music too loud?

WORLD/SPAIN (Agencies) More than 80 decibels (dB) on an MP3 or MP4 can, and is, causing an increase in hearing problems among the 10 to 35 year old population, according to a convention of international experts at a course in Audiology held in Barcelona. They agree that the number of people in that segment is increasing rapidly, and have called on manufacturers to install 'sound limiters' in their products. According to Professor of ENT at the University of Barcelona, Joan Domènech Oliva, 4% of the population suffer from continuous sound in the ear, which is caused by excessive noise and is uncurable. Some 1.5 million people have it in Spain, 80% of which are young.>
Domenech points out that while cases of labour related hearing and noise-related problems decreased considerably among workers when legislation was established on the subject, the total number has not shown a downturn because of the number of cases among the unprotected young.

The experts reccommend that if, on leaving a discotheque or a concert, a youngster hears whistling in the ear, which persist for several hours, they should see their doctor so as to treat a problem that could mean total deafness in a few years. "The sound at some concerts and discos has been measured at 125 dB; the danger point is above 80 dB," says Domenech.

The convention also dealt with the importance of early detection of deep deafness (hipoacusia) in children, as if this si treated adequately before age 3, it is possible that the child will attain the hearing age of a five year old. Neo natal detection means that some 1200 children with deep audial loss can be rehabilitated.

Undetected at the pre-lingual stage, deep audial loss represents costs of some €750,000 during the patient's lifetime, principally in special education needs and difficulties in finding a job. Light hipoacusia has a cost of €183,000, moderate deafness, €350,000, and severe deafness, €550,000, according to information emanating from the meeting.
