How do humans hear the intensity of a sound?
Sound intensity or acoustic intensity (I) is defined as the sound power Pac per unit area A. The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity. Our eardrums and microphone diaphragms are moved by sound pressure deviations (p), which is a sound field quantity. So we measure the sound with a SPL meter (Sound Pressure Level).
What sound intensity level would you expect to be painful to most humans?
120 decibels
How does tubular bells make sound?
Sound is vibration (of air ... as we humans perceive it). If a bell, tubular or otherwise, is made to vibrate then it will cause the adjacent air to vibrate ... and we call it sound.
When you refer to the hue of a light wave your referring to what you perceive as?
intensity
Sound intensity decreases when what decreases?
Sound intensity decreases when amplification (volume) decreases.
How does humans perceive changes in frequency?
cochlea of ear perceive and respond to various frequencies in sound...

Loudness is the human perception of sound wave?
The amplitude of sound waves is what humans perceive as loudness.
Is intensity a property of sound?

What is the name of sound intensity?
Sound intensity is mesured in decibels !
Sound intensity decreases when what decreases?
Sound intensity decreases when amplification (volume) decreases.
Why do humans see different colors?
You have receptors for three primary colours in your retina. You can perceive the thousands of colours due to stimulation of the these receptors at different intensity in various permutations and combinations.
