What is the cause of an increase in volume (audio)

Click For Summary
SUMMARY

The increase in audio volume is directly related to the force exerted by the sound waves rather than the frequency of the waves themselves. For a given frequency, the perceived loudness depends on the intensity with which the sound waves strike the eardrum. Stronger sound sources generate more powerful waves, resulting in higher volume levels as the sound disperses from the source. Understanding this relationship is crucial for anyone studying acoustics or audio engineering.

PREREQUISITES
  • Basic understanding of sound wave properties

This is just a question I posed to myself while learning about waves, I was wondering how the volume of an audible noise is increased or decreased, is it related to the compression of the wave and therefore the force generating it? If somebody could explain this in mathematical terms or provide a link to where I can find out more I would be grateful

For any given frequency, the "loudness" of the sound to the human ear will depend on the force with with the frequency is generated. It's not the the compression waves hit the eardrum with a different frequency, it's that they hit it harder. Sound disperses as it leaves a source so a stroner source delivers stronger waves to any given point out away from it.
