What is the maximum possible sound level in dB of sound waves in air? Given that density of air

=1.3 \mathrm{~kg} / \mathrm{m}^3, v=332 \mathrm{~m} / \mathrm{s}

and atmospheric pressure

P=1.01 \times 10^5\,\mathrm{~N} / \mathrm{m}^2

View answer and explanation

Correct option: A

190 dB

Option A (190 dB) is correct because it represents the sound level when the pressure variation equals the atmospheric pressure, which is the theoretical maximum.

A mercury column of length 0.1m is filled in its middle and in rest two parts air is filled at atmospheric pressure. When tube is turned to vertical position, then displacement of mercury will be (standard pressure = 0.76 m of Hg) A tuning fork produces waves in a medium.
