HEARING PROTECTION
Terminology
"Decibel" means a unit of sound pressure level, abbreviated as dB
They are measured in logarithmic scale.(i.e. 20
decibels is 10 times the intensity of 10 decibels, and 30 decibels is 100 times as intense as 10 decibels)
"dB(A)" means a unit of sound level expressed in decibels (dB) and A-weighted.
A - weighted means measuring the sounds within the audible frequencies. (20hz to 20 kHz).
Terminology
Noise Reduction Rating: It is a standard measure of sound blocking
capabilities of any hearing protective device.
Attenuation - Noise Reduction. Time-weighted average sound level
That sound level, which if constant over an 8-hour exposure, would result in the same noise dose as is measured.
Noise Levels
Hearing Protector
To be used when sound level exceeds 85 dBA.
Ear Plugs
Types Pre-moulded (preformed) or mouldable (foam ear plugs).
Available as disposable products or reusable plugs.
Recommended for high noise situations (up to 100dBA TWA).
Advantages are, Most suited to be worn when exposed to continuous exposure. Can be combined with ear muffs for additional protection Can be used with other personal protection equipment Comfortable for a wide range of ear sizes
Ear Plug - Usage & Maintenance
Checking the fit of Ear Plug Check the fit by talking out loud. The voice should sound hollow, as
if talking in a barrel.
Gently pull on the ear plug; it should not move easily.
1/4 of the plug should be outside the ear.
Maintenance of Earplug Do not use hand creams or lotions immediately before rolling and
inserting the plug
Do not clean ear plugs with alcohol or other disinfectants.
Do not wear ear plugs if there is any drainage from your ear
Do not re-inserting dirty or soiled ear plugs
Ear Muff
Ideal for users who need intermittent hearing protection against noise.
Recommended for those who prefer not to wear ear plugs. Recommended for situations where people move in and out
of noise often during the work day.
Ear Muff - Usage & Maintenance
Guidelines for use Check the fit by talking out loud. The voice should
sound hollow, as if talking in a barrel. The muffs should not be easily displaced while
performing regular functions.
Storage & Maintenance To be stored flat and away from high heat areas &
areas of excessive dust, dirt or moisture. Use Mild soap and water to clean. Do not use Solvents.
Combined Usage
Sound Level more than 105 dBA combined usage of ear plug & ear muff
recommended. dual protection only adds 5 dB to the Noise
Reduction Rating (NRR) of the more protective of the two devices.
Significance of Continuous Usage
Percent time used Maximum Protection
50% 3 dB
60% 4 dB
70% 5 dB

90% 10 dB
95% 13 dB
