Want this question answered?
the loudness of sound depends on the amplitude of the waves that compose it, i.e. the difference in pressure between the crest and the trough of the wave.
one or more octaves.
the Decibel it measures the loudness and intensity
loudness is the level of sound source while frequency define the repitition rate of that sound source. NAVNEET KUMAR,SRFTI,KOLKATA, email add: kmr_verma@yahoo.com
so...saying about acoustic waves for e.?amplitude influences loudness and frequency - pitch of tone
From what I know from highschool/early university simple harmonic motions, I believe that there is no necessary link between loudness and frequency. Frequency (the number of times a wave completes an oscillation or cycle in one second) decides the pitch of the sound, while amplitude (the difference in height between the highest point in the sound wave and the lowest point) decides the loudness of the sound.
Volume (loudness), pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
There are approx. 84 miles between Chicago, IL and Rockford, IL.

The loudness cannot be measured, because it is a personal psycho acoustic perception, and differs with each listener. The sound pressure level, a physical phenomena, can be measured by a SPL meter. See related link.
Low frequency = low pitch = long waves
In terms of a wave, the pitch of a sound is determined by its frequency, which is also in inverse proportion to its wavelength. The loudness/volume of a sound is determined by the amplitude of the wave. Both higher frequency and higher amplitude signify more energy in a wave.
