We have now observed for this small sound wave-length that, when the sound intensity is slowly increased, the number of these maxima diminishes. Further, the emphasis appears to shift towards the ...
The intensity level of higher or lower tones must be raised substantially in order to create the same impression of LOUDNESS. The PHON scale was devised to express this subjective impression of ...
The electroacoustic equivalent to SPL is measured with a VU METER. Because the square of the sound pressure is proportional to SOUND INTENSITY, SPL can be calculated in the same manner and is measured ...
