WebPut simply- A weighting measurements are designed to mimic how humans intuitively perceive noise that is below 100 decibels in volume. The loudness of the noise is measured in A-weighted decibels and is abbreviated to dBA. The dBA scale closely matches the loudness of sounds as perceived by the human ear. WebThe sound is the vibration of the medium, in most cases the air, being picked up and interpreted by our hearing. If something is vibrating, it means creating the waves, in this case, the sound waves. And every wave is defined by the frequency and amplitude. Most humans can hear the sound frequencies between 20 Hz and 20 000 Hz, or 20 kHz.
