Noise Induced Hearing Loss Simulator
Emma Shanks, Noise and Vibration Scientist, at HSE’s Science Division demonstrates what hearing loss sounds like and the difference between the hearing loss you might experience as you get older and the hearing loss you could experience if you have been exposed to workplace noise.

HSE Hearing Protection Demonstration
Maintaining your hearing protection and wearing it correctly with other Personal Protective Equipment makes a difference to the level of noise you are exposed to at work. But, what can reduce the performance of your hearing protection?
Noise Level at the ear (approximately):
No Hearing Protection – 87dB(A)
Effective Hearing Protection – 70dB(A)
Hearing Protection with a stretched head band – 83dB(A)
Hearing Protection with damaged seals – 83dB(A)
Hearing Protection worn with safety glasses not designed to be used with hearing protection – 83dB(A)
Hearing Protection worn with safety goggles not designed to be used with hearing protection – 82dB(A)
Hearing Protection worn with a ‘face mask’ – 76dB(A)
Hearing Protection worn with a woolly hat – 82dB(A)
