Question

3. What is a decibel scale ? Explain it by giving suitable examples. How is hearing loss caused​

Answer 1

Answer:

A quantity of 10 dB is 10 times as intense as 0 dB. A quantity of 20 dB is 100, or 10^2 times, the intensity of zero dB. The scale follows this pattern so that, for example, a value of 80 dB is 100 times more intense than a 60-dB value. The table below shows the dB scale for power ratios used in electrical engineering.

Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.
