Answer 2

THE ANSWER IS FALSE

Explanation:

The human ear can hear two sounds separately only if they reach the ear after an interval of one-tenth of a second.

1. The sensation of sound exists in the human brain for about 0.1 sec.

2. This means that if it takes one tenth of a second for teo sounds to reach our ears , then we hear them as separate sounds.

3. If two sound waves arrive at the ear in a time interval less than 0.1 s.

4. Then we will not be able to distinguish the sound and can not hear them separately.
