Sound advice: turn down your music!

Last week saw the return of International Ear Care Day organised by the World Health Organisation (WHO) to raise awareness of hearing loss and to promote prevention of hearing loss.

A very big concern of mine is that more than one billion teenagers and young people around the world are at serious risk of developing hearing loss due to unsafe listening behaviours. According to data release by WHO, nearly half of 12-35 year olds in middle-income and high-income countries listen to dangerous levels of sound on devices like smartphones and MP3 players. Additionally, almost 40% of these young people are exposed to hazardous noise levels at entertainment venues like nightclubs, concerts and sporting stadiums.

As they go about their daily lives doing what they enjoy, more and more people (not only youngsters) are placing themselves at risk of hearing loss. My advice to everyone is to look after your hearing because once you lose it, it won’t come back. Hearing loss can have a devastating effect on your life. It can damage your physical and mental health, and have an adverse effect on relationships, education and employment.

The WHO defines an acceptable level of noise for prolonged exposure as 85 decibels – roughly the volume of heavy city traffic. As volume increases, safe exposure duration falls steeply. For example, it is not safe to spend more than 15 minutes around noise levels of 100 decibels, which is typical for sporting events, clubs and bars.

Everyone should protect their ears against hearing loss by wearing earplugs at noisy events. They should also keep the volume down on their personal audio devices, and try to limit use of these devices to fewer than 60 minutes per day.

If you feel your hearing is already being affected, I would highly recommend that you book a hearing test with a qualified audiologist.  How much time do your children spend listening to music, headphones seemingly permanently clamped to their heads?

Ear Safety This Guy Fawkes Night

The days and nights around Fireworks Night are extremely hazardous to your ears. Fireworks can cost you your hearing.

For the lucky ones, their hearing returns, but many must live with their hearing loss or tinnitus for the rest of their lives. There is no cure for noise induced hearing damage. But you can easily prevent it.

Two thousandth of a second is all it takes for an exploding firecracker to put out the noise intensity to put your hearing at risk for life. The burst of noise is so short that you may not sense its true intensity.

Perhaps you love the thrill of fireworks, but you better watch out and be aware that*:

• 1 in 10,000 people suffer permanent hearing damage because of fireworks
• Young adults under the age of 25 are three times more likely than other groups to suffer fireworks related hearing damage
• The loud sounds from fireworks can cause hearing loss if protection is not used. The noise levels produced by fireworks can reach 150-175dB. The recommendation from World Health Organisation is not to be exposed to more than 140dB of peak sound pressure for adults and 120dB for children.
• Infants generally experience the greatest sound pressure and should not be exposed to fireworks.

Take Precautions

Guy Fawkes Night will be celebrated but take care of yourself and each other. Use earplugs to protect your hearing. Simple off the shelf ear plugs would do the trick and for the little ones there are fantastic, inexpensive noise breaker ear defenders - which look pretty cool also.

Make sure that no one else is standing too close when you light the fuse of your fireworks. Most of those suffering hearing damage did not cause it themselves. They suffered the bad luck of being too close to the fireworks of others.

If dealing with fireworks of 170 dB, adults needs to be 15 to 20 meters away from the fireworks before they are at a safe distance, while children have to be 50 to 60 meters away from the same fireworks.
