Hearing Protection

Hearing Protection

HSE Control of Noise at Work Regulations

The Control of Noise at Work Regulations 2005 came into 

force for all industry sectors in Great Britain on 6th April 

2006 (except for the music and entertainment sectors 

where they came into force on 6th April 2008). The aim of 

the Noise Regulations is to ensure that workers’ hearing is 

protected from excessive noise at their place of work, which 

could cause them to lose their hearing and/or to suffer from 

tinnitus (permanent ringing in the ears). 

The level at which employers must provide hearing 

protection and hearing protection zones is now 85 decibels 

(daily or weekly average exposure) and the level at 

which employers must assess the risk to workers’ health 

and provide them with information and training is now 

80 decibels. There is also an exposure limit value of 87 

decibels, taking account of any reduction in exposure 

provided by hearing protection, above which workers must 

not be exposed. 

More information can be found at 

www.hse.gov.uk/noise

HML

HML is High, Medium and Low and is literally how the 

protector performs at high, medium and low frequencies. 

The values (attenuation level) of each will be found on the 

packaging of the hearing product you purchase. A SNR of 

30 will not necessarily give a 30 decibel attenuation at all 

frequencies.

Rule of Thumb

When it is necessary to shout in order be heard three 

feet away, the noise levels may be 85 decibels or more. 

Hearing protection must be made available to employees 

where sound levels are at or above 80 decibels, and strictly 

enforced where the sound levels reach or exceed 85 

decibels.

Products comply to EN352.
