The human ear can detect from 0 dB to 120 dB without suffering damage. Some pelople can hear sounds that are quieter than 0 dB. Sounds louder than 120 dB can be expected to be painful and may result in damage to the eardrum and other parts of the ear. Sounds above about 85 dB, if heard regularly for extended periods of time may cause loss of hearing that cannot be repaired.

The normal measure of noise related to human hearing is PNdB or Perceived Noise deciBels. This is a logarithmic scale like all dB, but is weighted for frequency response. A man with normal hearing can just perceive 0 dB. The scale was in fact designed with this in mind. At the other end of the scale is the "pain threshold" where sound starts to cause pain. For most people this in the region of 110dB - 120 dB. Ear defenders should be worn well before these levels are reached.

This widely varies between humans according to their age and how many loud noises have damaged their ears over time. However for most humans the average is about a 20.0 Khz. I am not sure what this would be in decibels.

That depends a lot on whether it is short-term or long-term.The Wikipedia article "Sound pressure" lists the following thresholds:

* A long-term exposure to 85 dB (at ear) can cause hearing loss.

* A short-term exposure of 120 dB (at ear) can cause hearing loss.

However, the U.S. EPA has specified a lower limit, of 70 dB, to protect against hearing loss, as well as sleep disturbance and other disturbances. So, I guess this latter figure is the best answer to the question.

The decibel level at the threshold of human hearing is generally considered to be around 0 decibels, which corresponds to the quietest sound that can be perceived by the average human ear.

The threshold of hearing is 0 dB, really.

What is the difference between threshold of hearing and absolute threshold of hearing?

The threshold of hearing refers to the quietest sound that can be detected by the human ear, typically around 0 decibels. The absolute threshold of hearing, on the other hand, is the lowest intensity at which a sound is perceived 50% of the time--it may include factors like frequency and duration.

What is the scale used to define sound intensities?

Sound intensities are typically measured in decibels (dB), which is a logarithmic unit used to quantify the intensity of sound. The decibel scale compares the intensity of a sound to a reference level, usually the threshold of human hearing.
