Question 1: Which of the following statement is TRUE of sound intensity and decibel levels? Identify all that apply.
The intensity of sound which corresponds to the threshold of pain is one trillion times more intense than the sound which corresonds to the threshold of hearing.
Two sounds which have a ratio of decible ratings equal to 2.0. This means that the second sound is twice as intense as the first sound.
Sound A is 20 times more intense than the sound B. So if sound B is rated at 30 dB, then sound A is rated at 50 dB.
A machine produces a sound which is rated at 60 dB. If two of the machines were used at the same time, the decibel rating would be 120 dB.
