Title: Incredible Sound Levels from Firecrackers!

Question:

If two firecrackers produce a sound level of 81 dB when fired simultaneously at a certain place, what will be the sound level if only one is exploded?

Answer:

77.96 dB

Have you ever wondered how loud a firecracker can be? The intensity of sound produced by firecrackers is truly incredible! Let's dive into the fascinating world of sound levels and decibels.

When two firecrackers are fired simultaneously, they produce a sound level of 81 dB. But what happens when only one firecracker is exploded? The sound level decreases slightly to approximately 77.96 dB.

Decibels are a unit of measuring the intensity of sound, and they depend on the logarithm of the sound intensity. The formula for calculating sound intensity in decibels is: I(dB) = 10log(I/I0).

For the case of the two firecrackers with a sound level of 81 dB, the intensity of the sound is calculated to be 0.000125 W/m^2. Therefore, when only one firecracker is exploded, the intensity is halved to 0.0000625W/m^2, resulting in a sound level of 77.96 dB.

Next time you hear the loud pop of a firecracker, remember the science behind its sound level and intensity!
