The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea. Originally Answered: What’s the maximum decibels a human can tolerate? It is agreed that 144 dB for a very short time-span (not even a second) is enough to cause permanent integral hearing loss.

Anything that is louder than 85 dB can cause hearing loss. Believe it or not, the amount of time you are exposed to high decibels of sound is just as important as the rate of decibels. So, an occasional loud noise may cause you less loss then a long time of a much quieter sound. The Human Ear: A detailed diagram of the human ear.
