A decibel chart shows the intensity levels of common environmental sounds, which range from 0 dB to 140 dB (the threshold of pain). Some points of reference on the decibel chart include the following: 0 dB - The softest sound a person can hear with normal hearing 10 dB - Normal breathi...
High-frequency sounds of 2 - 4,000 Hz are the most damaging. The uppermost octave of the piccolo is 2,048 - 4,096 Hz. Aging causes gradual hearing loss, mostly in the high frequencies. Speech reception is not seriously impaired until there is about 30 dB loss; by that time severe dam...

The answer is that it depends: our ears are complicated mechanisms whose sensitivity varies with frequency, and it is important to remember that you can feel as well as hear some sounds. To start, it is worth taking a look at anequal loudness curve. You’ll notice that the threshold of ...
