Explanation:
High frequency noise is 2000 Hz and above. Mid-frequency noise falls between 250 and 2000 Hz. The amplitude of sound is expressed in decibels (dB). This is a logarithmic compressed scale dealing in powers of 10 where small increments in dB correspond to large changes in acoustic energy.
