Noise, or noise pollution, is measured in

  • A.Phon
  • B.Deci
  • C.Decibel
  • D.Decimal

Answer: C

The decibel measures the loudness or intensity of sound.

It is logarithmic: 10 dB is a tenfold increase in intensity, so the scale can cover the enormous range the ear handles. Frequency, which determines pitch, is measured in hertz instead - cycles per second.
