This is where personal protective
equipment, or PPE, comes in. There is a
range of equipment available to pump
engineers providing diff erent levels of
sound mitigation. The most commonly
used items of PPE for the prevention of
NIHL are earplugs or earmuff s, which
mitigate the amount of sound which is
allowed to enter the eardrum. This
means less pressure on the sensitive hair
follicles within the eardrum that pick up
the sound.
