Especially, the reduction effect performs in the most annoying sound range (Hz).
dB (decibel): A unit that expresses noise level and loudness. The higher the value, the louder the noise.
Hz (hertz): A frequency that represents the pitch of a sound.
This means the number of times a sound wave rises and falls per minute;the higher the value, the higher the sound.
