TWA 76.21 dBa

1.    (20 pts) If an employee is exposed to continuous sound levels for 2 hours at 95 dB and is then exposed to sound levels below 65 dB for the rest of the 8 hour day, what is the employee’s 8 hour TWA in dBA using OSHA’s calculations? Does this employee exceed OSHA’s PEL? Does this employee need to be in a hearing conservation program?

 

TWA 76.21 dBa, the employee does not need to be enrolled into the hearing conversation program because employees exposed to sound levels at or above 85dB as an 8-hour TWA requires monitoring.

 

How do you arrive to 76.21
