Misuse of headphones can cause hearing loss

Permanent tinnitus is the first symptom of hearing problems

According to experts, electronic devices that allow the use of headphones such as cell phones, Ipods, Ipads, portable computers – laptops, notebooks and netbooks – and mp3 players can harm the hearing health of their users, if exposure to sound is frequent and inappropriate.

The average maximum safe exposure for the human ear is 80 decibels. From that level onwards, exposure for more than 30 minutes puts hearing health at risk, and may trigger symptoms such as ringing in the ears, attention deficit and the need to repeat words in order to understand.

Headphones are considered the most harmful to the hearing aid because they emit barrier-free sounds directly to the eardrum. The World Health Organization (WHO) recommends that the maximum headphone volume does not exceed 65 decibels.

 “The sound from Ipods, MP3 headphones, can reach 120 decibels that go directly to the ears and cause, with that, damage to the hair cells of the cochlea, a sure path to early deafness”, says Prof. doctor Ricardo Ferreira Bento, full professor of the Discipline of Otorhinolaryngology at HC-FMUSP.

Tinnitus is the first symptom of hearing problems, before it causes any noticeable hearing loss. According to a survey carried out by HC, 35% of cases of tinnitus diagnosed by the hospital are linked to noise, either caused by acoustic trauma or excessive exposure to potentially harmful sounds.

Today, more than 560 million people have hearing problems on the planet and the forecast is that this number will reach 700 million in 2015 and 900 million in 2025, according to recent data from the British MRC Institute of Hearing Research, in the United Kingdom. In Brazil, it is estimated that 15 million people suffer from some type of hearing loss and that 350,000 are completely deaf. In addition, of the 3.1 million Brazilians who are born annually, less than 10% are evaluated for deafness.

As a result of this scenario, universities and institutions have joined forces in the research and development of new technologies for the treatment of hearing aids. The newest product launched in the country is a software called Hearing Guardian V1 – guardian of hearing, developed with exclusive technology Earlogic of Korean origin, which promises to diagnose, protect and treat hearing problems.

Research has shown that 6 to 7 out of 10 people who correctly received Earlogic technology treatment (twice a day for 30 minutes for two weeks) had hearing restoration of up to 10dB. The software can be downloaded free of charge from the Biosom website ( www.biosom.com.br ) for testing purposes.
