Hearing Protection Device
If engineering controls fail to maintain an 8-hour time-weighted average below 85 dBA, then a hearing protection device (hpd) is required. There are two general types of hpd’s: earplugs and ear muffs. Each one has its own benefits and drawbacks. The selection of the proper hpd to be worn is commonly done by an industrial hygienist so that the proper amount of noise protection is worn. OSHA requires that hpd be given free of charge.

Famous quotes containing the words hearing, protection and/or device:
“Orpheus with his Lute made Trees,
And the Mountaine tops that freeze,
Bow themselves when he did sing.
To his Musicke, Plants and Flowers
Ever spring; as Sunne and Showres,
There had been a lasting Spring.
Every thing that heard him play,
Even the Billowes of the Sea,
Hung their heads, and then lay by.
In sweet Musicke is such Art,
Killing care, and griefe of heart,
Fall asleepe, or hearing dye.”
—John Fletcher (1579–1625)
