self induced hearing loss & how to prevent it

Self Induced Hearing Loss

Attention has been focused on the potentially negative effects smartphones can have by way of emissions, privacy intrusion and unsafe driving practices. We haven’t yet shed sufficient light on the impact smartphones, MP3 players and other listening devices can have on our hearing.

1.1 Billion Young People Are at Risk of Hearing Loss

This has led to a situation where,  according to estimates by the World Health Organisation, about 1.1 billion young people worldwide are at risk of hearing loss due to unsafe listening practices.

Due to the prevalence of relatively cheap modern technology we are facing a sharp rise in self-induced hearing loss.  Luckily, however, state of the art remedies – including highly effective and almost invisible hearing aids- are available.

Prevention of Hearing Loss Requires a Change in Attitude

I have to admit that until recently my attitude towards hearing health care was fairly flippant. Only through my work for the Hearing Care Industry Association  have I begun to understand the magnitude of the issue and how it will affect us in the future if we don’t respond appropriately.

Hearing is something most of us take for granted, just like breathing and seeing. Our understanding of good hearing care is limited – unless we are professionally or personally involved with the issue. Most people don’t think much about their hearing until they have an issue with it.

But that is about to change because hearing has made it onto the main agenda, and for good reason. There is a hearing loss epidemic on its way which, to a large extend, is entirely preventable.

Illustrating a Case In Point

Recently a man brought his 3 year old daughter to a meeting I attended. To ensure she  didn’t disturb proceedings, he allowed her to listen to a story on an MP3 player and although I sat at the other end of a large meeting table I could hear what she was listening to through earbuds (also known as inner ear head phones or earphones).  I spontaneously drew attention to the fact that she was listening to the story too loudly, thinking the dad had not noticed and would tell her to turn it off or down. I even mentioned there is a setting for safe listening levels on most of these devices and received a very sharp reaction to mind my own business and that his daughter is old enough to adjust the sound herself according to her choice.  The situation remained with me. It indicated vividly the widespread lack of awareness of the real risks associated with the technology. The girl was definitely too young to know about safe listening levels or to judge the long term consequences of her behaviour and the father was obviously unaware as well. How can this situation be changed?

Estimating the Extend of Hearing Loss

The World Health Organisation (WHO) estimates that:

  • about 1.1 billion young people are at risk of hearing loss due to unsafe listening practices.
  • Over 43 million people 12 to 35 years live with disabling hearing loss.
  • Among young people 12 to 35  years in middle and high-income countries nearly 50% listen to unsafe levels of sounds through personal audio devices such as MP 3 players, smartphones and other devices. Around 40% are exposed to potentially damaging levels of sound at nightclubs, bars and sporting events.

Preventing Hearing Loss

The WHO proposed several preventative actions to be applied on a personal level:

  • keep the volume down – some devices have in-build safe levels we can set as a default so you don’t get tempted or surprised and when attending loud venues we could wear earplugs.
  • limit the time spent engaged in noisy activities – in noisy venues get a break as often as possible and limit the use of devices to one hour a day.
    heed the warning signs of hearing loss like ringing in the ears, difficulty of following conversations in groups, difficulty with high pitched sounds and understanding speech on the telephone.
  • monitor safe listening levels through use of smartphone apps.
    get regular hearing check ups – most hearing care businesses offer these check ups free of charge.

The WHO also recommends wider action which specific sections of society can undertake and which could translate into a social marketing awareness raising campaign about hearing health and hearing loss.

  • Parents, teachers and physicians are being called upon to educate young people;
  • Managers of entertainment venues must comply with the noise limits set and provide chill out areas where people can get a break from the noise; offer ear plugs and employ sound limiters;
  • Manufacturers can design devices with healthy listening safety settings and display instructions about the safe use of their devices;
  • Governments can develop and enforce strict legislation about recreational noise and run information campaigns.

We need to act urgently. Hearing loss has significant repercussions for those affected as well as for society at large. The most obvious effect is that it is socially isolating and this isolation has other side effects. Hearing impairment also impacts an individual’s ability to find employment.

Interestingly, the current production of hearing aids meets less than 10% of the global need. Hence, while we educate everybody at all levels about the need for hearing health and preventative measures, we also need to facilitate the production of sufficient hearing aids and deal with the issue of access and affordability.

Hearing Awareness Week will be held in Australia from 23 to 29 August, a good time to debate the future of ear and hearing care.  And just remember, we will also collectively pick up the bill for the hearing damage and loss of productivity resulting from hearing loss.

    It’s good to know that there are services that offer hearing check ups free of charge :) But disturbing to read that father’s comment to you of his 3 year old daughter :(

    • I know, what a jerk! And yes, most people don’t realise but in a lot of shopping centres they offer hearing tests at one of the hearing aid offices and there are hundreds of them around Australia.

    Interesting. I’m definitely guilty of listening to music too loud. This info definitely makes me think about it!

    • I know Christel, it is insane but I always took my hearing completely for granted. It is so nice to listen to loud music sometimes .. I think the main issue is if you do it for too long and right inside your ears… Ulrike
