Regulatory groups such as OSHA have set legal limits as to how much noise a worker in Louisiana or elsewhere in the country may be exposed to. The exposure limit per OSHA regulations is 90 decibels per eight hours worked. This is considered to be a 100 percent noise dose. However, workers may be exposed to greater volumes depending on how long that they are exposed to them.
If a worker is going to be exposed to a noise for 15 minutes, OSHA allows it to be as loud as 115 decibels. If a worker is exposed to noise for an hour, the maximum allowable volume would be 105 decibels. NIOSH standards are slightly different than OSHA standards in that a worker may only be exposed to a maximum volume of 85 decibels over a period of eight hours.
