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.
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 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.
A human can typically hear sounds in the range of 0 to 140 decibels. However, the threshold of pain for most people is around 120-130 decibels.
The threshold of human hearing for low-frequency sounds, such as those produced by a subwoofer, is typically around 20 decibels. However, the ability to perceive sounds at such low levels can vary among individuals.
On average, the human threshold for pain from sound is around 120-130 decibels. However, sustained exposure to sounds over 85 decibels can cause hearing damage over time.

Fire engine is 120 Decibels which is also the threshold of pain.
A crowing rooster can have a crow that is upwards of a decibel level of 70. This can be comparable to the decimal level of a raised human voice.

Human hearing is typically between 20 Hz an 20,000 Hz
The decibel level for standard human voices is around 60 decibels, which is also the level for singing birds. Hearing loss occurs at around 110 decibels with painful hearing loss occurring at 130 decibels.
A decibel is the unit of measuring the level of sound.
What is the decibel level of a car horn?
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.
