The 5th-9th February 2018 is National Tinnitus Awareness.
Tinnitus is when you can hear sound from inside the body. People describe tinnitus as ‘ringing in the ears’, but other sounds like buzzing, humming, grinding, hissing and whistling can be heard too. Pulsatile tinnitus is when a person can hear sounds in their ear that beats in time to their pulse.
Tinnitus is caused by overexposure to loud noise. Depending on the noise intensity (decibels), depends on how long people should be exposed to the sound:
|Noise Intensity (db)||Exposure Time||Type of Sound|
|85||8 hours||Blender, Milling machine|
|88||4 hours||Forklift truck|
|91||2 hours||Tube train|
|97||30 minutes||Industrial fire alarm|
|100||15 minutes||Bulldozer, handheld drill|
|103||7.5 minutes||MP3 player at full volume|
|109||112 seconds||Crying baby, Jackhammer|
|112||66 seconds||Live rock band|
|115||33 seconds||Emergency vehicle siren|
Places where you’d be likely to be exposed to loud noises in a working environment include:
If you or your staff are exposed to loud noise for prolonged time, they may hear ringing or buzzing in your ears for some time afterwards. This can cause permanent damage if you allow yourself to be constantly exposed to it.
First you need to ensure your workplace is a safe environment for noise. You will need to conduct a noise risk assessment. If the levels of noise are higher than acceptable (85 decibels), you must by law act upon it.
You can begin by lowering the noise of equipment with vibration isolation, damping or enclosing a barrier to prevent sound from reaching the worker. If none of those options are viable, then hearing protection is the solution.
Your workplace should identify hearing protection zones (ideally with signs), where you and your employees will be required to wear ear protection.
Hearing protectors should be able to be worn with other protective equipment such as hard hats, dust masks and eye protection. However, be careful that the protectors do not isolate too much sound, and this can be just as dangerous.
Not cotton wool!
Ear muffs or plugs are best for noise that are 100 decibels and up, depending on how long your employee is exposed to the sound.
We have worked with our clients over the last 20 years, ensuring noisy working environments are made safe for workers.
