120Db
The threshold of hearing is 0 dB. The threshold of pain = 137.5 dB.
The human ear can typically detect sound intensities ranging from about 0 dB (threshold of hearing) to 120-130 dB (threshold of pain). Sounds below the threshold of hearing are too faint for the ear to detect, while sounds above the threshold of pain can be physically uncomfortable or damaging to the hearing.
Sound above the upper threshold of hearing is called ultrasound. It is typically defined as sound with frequencies higher than 20,000 Hz, which is the upper limit of human hearing.
The absolute threshold of hearing is the lowest possible tone/decibel you could possibly hear. (This differs form person to person). The Differential Threshold is the point at which a person recognizes the decibel level has changed.Hope this answers your question, just learned this in psychology!
Human hearing is typically between 20 Hz an 20,000 Hz
The average human can hear sounds ranging from 0 dB (threshold of hearing) to around 120 dB (threshold of pain). However, the range of comfortable hearing is typically between 20-70 dB for most people.
Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.
The dynamic range of hearing refers to the range of sound intensities that the human ear can perceive, from the quietest sound that can be heard to the loudest sound that can be tolerated without causing damage. In general, the dynamic range of human hearing is about 120 decibels, with the threshold of hearing around 0 decibels and the threshold of pain around 120-130 decibels.

Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.
It varies from person to person. However - an accepted 'normal' hearing range is around 20 Hz to 20,000 Hz. The same goes for pain threshold - anything over 120 dB would certainly be uncomfortable for most people.
Absolute threshold is the smallest level of energy required by an external stimulus to be detectable by the human senses, including vision, hearing, taste, smell and touch
