A compressor in a mechanical room was measured at 5 feet from the source to have a sound pressure level of 90 dB. What would the sound pressure level be at 10 feet from the source?

A compressor in a mechanical room was measured at 5 feet from the source to have a sound pressure level of 90 dB. If a second identical compressor was placed immediately next to the first, what would the resulting sound pressure level measurement at 5 feet be?

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?

Please show all work.
