Let’s reduce noise-induced hearing loss


INAD 2024

Jakarta, IO – International Noise Awareness Day (INAD) is celebrated every final Wednesday of April. This year, the commemoration, often called “INAD” falls on April 24. INAD is celebrated to raise awareness about the negative impacts of noise pollution on the health of individuals and communities. The impact of the disorder can be hearing loss, disorders of body organs such as the stomach and blood circulation, as well as stress, which can result in mental and psychological disorders.

Dr. dr. Nyilo Purnami, Sp.THTKL(K), FICS, FISCM, ear nose and throat specialist doctor from the Dept. of Otorhinolaryngology-Head and Neck Surgery, Faculty of Medicine Airlangga University, Surabaya, pointed out that the use of inappropriate earphones or headphones has the potential to interfere with hearing, depending on the type of earphone, volume, and duration of exposure. “Continuous noise causes hearing fatigue in the cochlea, which can then result in permanent damage. This condition is also called noise-induced hearing loss (‘GPAB’). Hearing loss due to noise is often not realized by the sufferer,” she explained. 

Tinnitus Symptom 

Criteria for a sound defined as “noise” are if the intensity is above ≥85 db. We are told that the most damaging frequency is >1000 Hz. The longer the exposure, hearing loss will be irreversible. The criteria for hearing loss with air conduction hearing thresholds are as follows: mild deafness if 25-40 dB; 40-55 dB moderate; 55-70 dB even moderate-severe; 70-90 dB heavy; greater than 90 dB very severe deafness. 

“Early symptoms of hearing loss include difficulty understanding conversations; hearing high sounds/frequencies; tinnitus, usually occurring in both ears; and there is a history of noise exposure. To avoid hearing loss, choose a headset that suits your ear anatomy; application the rules for using headsets/earphones: 60% volume for 60 minutes; rest 15 minutes after use. Don’t forget to do regular hearing checks and also inspect the ear canal for wax or infection.”

Let’s reduce potential hearing health risks by paying attention to the sounds we create ourselves; respecting the rights of others to a peaceful and quiet environment; turning down the volume of radios, televisions, and personal stereo systems; do not sound the vehicle horn, except in cases of danger; and always wear appropriate protection if you have to be in a noisy environment.
