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).

How do humans perceive sound intensity?
60 desibell
What sound intensity level would you expect to be painful to most humans?
120 decibels
What is most often used to measure the intensity of a sound?
The intensity of sound is most often measured by the Decibel meter. It can also be called the sound level meter or the dB Meter. It is used to accurately and objectively measure the sound or noise that one can hear.
Sound intensity decreases when what decreases?
Sound intensity decreases when amplification (volume) decreases.
What describes the intensity of sound?
Sound intensity or acoustic intensity is defined as the sound per unit area. The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity.
How does intensity affects how you hear?
It's not the sound intensity I (acoustic intensity) as sound power quantity, it's the sound pressure p as sound field quantity, which moves you ear drums. I ~ p²

What is the range of frequency that humans can hear?
the range of sound frequencies that humans can hear is about0to200Hz
What frequencies can humans hear?
We can hear almost all amplitudes(except very small amplitudes). Amplitude determines the intensity(i.e., loudness) of sound wave. Intensity is proportional to Amplitude squared. So there is no upper limit for amplitude. But very loud sound(high amplitude wave) can be harmful for ears. Actually there is a frequency range(20Hz to 20kHz) that we can hear.

Is intensity a property of sound?
Sound intensity is a property of sound.
What frequencies of sound can humans hear?
typically 20-20000 Hz - but this range will decrease with age
As sound intensity increases you hear the sound as a louder sound at the same pitch this suggest what?
There we got: Subjectivly sensed loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power). Scroll down to related links and study: "Dependance of sound levels and the corresponding factors".
What is a description of what is actually heard?
Audible sound is what is actually heard. Some people will interpret audible sounds differently depending on their ability to hear as well as their perceptions. Animals can "hear" sounds that humans cannot hear. There are ranges of sound that are normal for humans.
How do you spell soud?
If you mean a noise humans hear, it is spelled sound. The gun made a loud sound.
What is the name of sound intensity?
Sound intensity is mesured in decibels !
