World Hearing Day
Hearing loss and deafness
The 3rd March is World Hearing Day, each year the world Health Organisation aim to increase awareness of hearing loss and deafness not just from working environments but from infection, genetic factors and disease.
Over 5% of the world’s population require rehabilitation to address their disabling hearing loss (including 34 million children). It is estimated that by 2050 over 700 million people – or 1 in every 10 people – will have disabling hearing loss.
Disabling hearing loss refers to hearing loss greater than 35 decibels (dB) in the better hearing ear.
Normal hearing is a range of decibel levels (dB) that typically falls between -10 dB and 20 dB. Someone with normal hearing can hear sounds at every pitch within this range.
Different degrees of hearing loss
Slight: 16 to 25 dB
Mild: 26 to 40 dB
Moderate: 41 to 55 dB
Moderately severe: 50 to 64.9 dB
Severe: 71 to 90 dB
Profound: Greater than 90 dB
In the working environment decibel levels must be monitored to ensure they do not exceed the action levels specified in the Control of Noise at Work Regulations. If they do suitable measures must be put in place.
There are many Apps available to monitor decibel levels without the need for expensive equipment, Apple watches have a decibel monitor that can also be used.
