18. Waves & Sound Sound Intensity
2PRACTICE PROBLEM
The threshold of hearing is defined using a reference frequency of 1000 Hz for a pure sine wave. The sound pressure amplitude at the threshold of hearing is defined by a pressure of 2.0 × 10-5 Pa. Determine the intensity at the threshhold of hearing.
