SOLVED: A 10-minute exposure to 120 dB sound typically shifts your threshold of hearing temporarily from 0 dB up to 28 dB. Studies have shown that, on average, 10 years of exposure to 92 dB sound causes a permanent shift of up to 28 dB. What intensities correspond to 28 dB and 92 dB?

A 10-minute exposure to 120 dB sound will typically shift your threshold of hearing at 1000 Hz from 0 dB up to 28 dB for a while. Ten years of exposure to 92 dB sound will cause a permanent shift up to 28 dB. What intensities (W/m?) correspond to 28 dB and 92 dB?

SOLVED: A 10-minute exposure to 120 dB sound will temporarily shift your threshold of hearing at 1,000 Hz from 0 dB up to 28 dB. Ten years of exposure to 92 dB sound will cause a permanent shift to 28 dB. What sound intensities correspond to 28 dB and 92 dB? (Io = 10^-12 W/m^2)
