It is well established that long-term exposure to loud noise can damage hearing, sometimes irreparably.

But few people understand how to assess loud noise. And although sound meters are now available as apps on most smartphones, not everyone is in the habit of using them.

Many people unintentionally damage their hearing by listening to music through headphones for long periods.

To give an idea how sound is measured, a faint whisper clocks in at 30 decibels (dB).  Normal conversation is around 60-70dB. Sound becomes dangerous at 85dB. Health and safety regulations govern workplace exposure to noise above this level.

For example, a normal garden lawnmower will generate a sound around 90dB – heavy city traffic around the same. Your ears can tolerate around eight hours of exposure to this level of sound. Anything more poses a risk to your hearing.

Above this level, tolerance levels drop off sharply. A motorbike engine makes a sound around 95dB. More than four hours exposure can cause damage. A chainsaw is typically louder, around 100dB – more than two hours of this will cause problems.

Sounds above 125 dB, such as a siren or a firecracker cause physical pain, while sounds at 140dB, such as a gunshot or a jet plane at take-off, pose an immediate risk to hearing.

Here are some other sample sound levels and tolerances:

105 dB: Jackhammer, helicopter – one hour maximum

110 dB: A snowmobile – 30 minutes

115 dB: A baby’s cry, roar from a stadium football – 15 mins

120 dB: Rock concert, sandblasting – 7.5 minutes

In order to protect your hearing, Hidden Hearing recommends that you follow the 60/60 rule, to listen to music devices through headphones for a maximum period of 60 minutes at 60% volume.

If you are concerned about any aspect of your hearing healthcare, you can make an appointment to have a hearing evaluation conducted free of charge at any of the 65 Hidden Hearing branches nationwide. To book call 1800 370 000 or visit www.hiddenhearing.ie
