Question

What is the sound intensity of a noise that is 130 dB

Answer 1

Answer:

10 watts per squares meter

Answer 2

Answer: When the defining level of 0 decibel (10-12 watt per square metre) is taken to be at the threshold of hearing for a sound wave with a frequency of 1,000 hertz, then 130 decibels (10 watts per square metre) corresponds to the threshold of feeling, or the threshold of pain.
