Quality (or timbre) of a sound depends on:

Four sources of sound each of sound level $10\,dB$ are sounded together,the resultant intensity level will be ... $dB$

$A$ small speaker delivers $2\, W$ of audio output. At what distance from the speaker will one detect $120\, dB$ intensity sound in $cm$?

In an orchestra,the musical sounds of different instruments are distinguished from one another by which of the following characteristics?

$A$ source of sound emits $200\pi \text{ W}$ power which is uniformly distributed over a sphere of $10 \text{ m}$ radius. What is the loudness of sound on the surface of the sphere?

When we hear a sound,we can identify its source from
