The 3M Occupational Health and Environmental Safety
Division has been helping to protect people at work for
30 years.
Excessive Noise and Hearing Loss
The Dangers of Over Protection
It may be tempting to pick the hearing protection with the highest level
of protection (or attenuation), however ‘over attenuation’ can bring its
own problems. If the sound level at the ear is reduced too far, the wearer
can become isolated, unable to hear colleagues‘ voices, moving vehicles,
warning sounds, or alarms
Hearing loss caused by exposure to noise at work continues to be a
significant occupational illness.
Step by step guide to using the Optime™ Alert System and Sound Check Meter
1. Measure the noise level
2. Identify the corresponding icon
A detailed noise assessment which you may have already carried
out will identify the noise level.

Noise Regulations
Under the Control of Noise at Work Regulations 2005 a new Limit Value
of 87dB(A) at the ear (under hearing protective equipment) must not be
exceeded, and the Upper Action Level becomes 85dB(A) and the Lower
Action Level becomes 80dB(A).
Whilst a reduction of 5dB(A) may not at first glance appear significant,
it is worth noting that a reduction of just 3dB(A) is roughly equated to
halving the sound energy level.
The Optime™ Alert System by 3M makes for a
quick and easy Hearing Protection Equipment
selection process
Choosing the correct hearing protection for your needs can be difficult;
the hearing protectors should neither over nor under protect the user.
With this in mind 3M has an easy to use Optime™ Alert system for 3M™,
E-A-R™ and Peltor™ Branded Hearing Products that aids correct selection
of hearing protection appropriate to noise level.
Alternatively the 3M™ Optime™ Sound Check Meter
will indicate the average noise in your work place
area when left there to stabilise.
3. Choose your preferred hearing
protection equipment
PLEASE NOTE:
At levels above 95dB(A) you will need an accurate
noise assessment to correctly select the product.
Green and Yellow marked products are not suitable
for use in low frequency noise.
Use the icons related to the products to choose your preferred
3M™, E-A-R™ and Peltor™ Hearing Protection Equipment.
