Question

the human ear can hear two sound separately only if they reach the ear after an interval of one - twentieth of sound write true or false and correct the false statement​

Answer 1

Answer:

The human hearing range is a description of the pitches and loudness levels a person can hear before feeling discomfort.

There are a variety of sounds in our environment, ranging from faint sounds like birdsong and rustling leaves to louder sounds like music, yelling, and industrial noise. This human hearing range is called the audible range.

Loudness and pitch

The human hearing range depends on both the pitch of the sound – whether it is high or low – and the loudness of the sound. Pitch is measured in Hertz (Hz) and loudness is measured in decibels (dB).

For a person with normal hearing, when it comes to pitch the human hearing range starts low at about 20 Hz. That’s about the same as the lowest pedal on a pipe organ. On the other side of the human hearing range, the highest possible frequency heard without discomfort is 20,000Hz. While 20 to 20,000Hz forms the absolute borders of the human hearing range, our hearing is most sensitive in the 2000 - 5000 Hz frequency range.

As far as loudness is concerned, humans can typically hear starting at 0 dB. Sounds that are more than 85dB can be dangerous for your hearing in the case of prolonged exposure.
