what is low frequency acoustics
The laws of sound physics (acoustics) or How does it work? The human ear can generally hear sounds with frequencies between 20 Hz and 20 kHz (the so called âaudio rangeâ). 20 Hz is a very low frequency while 20 kHz is a very high frequency. Examples of low frequencies in our surroundings are the bass in music or the low humming that a fan generates. Examples of high frequencies are the treble in music or the high notes of a small child.
