Don’t use headphones for more than an hour at a stretch

Any sound intensity of 85db or less is considered safe; however, more than 90dB imposes a risk. Nowadays, most music devices emit sounds of 95-110dB.

Recently, Nasreen, who is in her mid-thirties, discovered that she could not bear to hear anyone shouting and would tell people at work and home to speak at a lower volume.

Why? The noise hurt her.

While this might be shrugged off as a rare occurrence, just take a look around at earphones, that went from being a mere accessory into a ubiquitous lifeline for our entertainment.

Earphones have become popular among all age groups and are becoming an increasingly popular sight. Yes, they look cool, but it has dangerous implications on your hearing, with the damage being temporary and in some cases, permanent. Dr Shyam Anil Pai, specialist ENT surgeon at Aster Clinic, Al Nahda, says that everywhere you look – on the streets, commuting by metro or cab, in the gym, etc – everyone is using headphones or earphones connected to their mobiles or portable listening devices.

“It is safe to use earphones or headphones. It is the volume of the music or audio played on these devices that cause harm and damages the inner ear. Individuals commonly speak at 60dB (decibel) and music should be played at a maximum of 80dB, and never exceed 85dB or more,” he said.

Exposure to noise levels of 100dB for more than 15 minutes is extremely harmful. However, irrespective of the noise level, it is recommended to use earphones or headphones for not more than an hour at a stretch.

There’s also the near-endless use of mobile phones in today’s busy world, with some people talking on the phone for several hours a day.

Current trends in the UAE show more people owning smartphone. This is rather significant compared to 15 years ago, says Dr Pai. “Even young children today have access to mobile phones. So, greater awareness needs to be created about the potential adverse health impacts associated with their overuse. In my daily practice, I mainly encounter patients in the age group of 20-35 years who have hearing problems attributable to excess mobile phone use. This is either in the form of tinnitus (ringing or whistling noise in ears) or high-frequency hearing loss. By curbing prolonged mobile phone use, the further deterioration of hearing is prevented.”

Use of wireless bluetooth

Bluetooth earphones are considerably better because they emit far less radiation than mobile phones. However, the level of noise the ear is exposed to is still a concern, says Dr Pai.

Any sound intensity of 85db or less is considered safe; however, more than 90dB imposes a risk. Nowadays, most music devices emit sounds of 95-110dB.

The exposure to this high-frequency sound for long periods causes damage to hearing receptors, known as hair cells.

There is no specific treatment for this kind of hearing loss, but patients are advised to avoid noise exposure as much as possible and go for regular follow-ups for assessment of hearing.
