One violin creates a sound whose intensity level is 60dB. Find the intensity level of 16 violins, each playing at this intensity
Yanka [14]

Answer:

72.04 dB.

Explanation:

The intensity level of 60dB corresponds to the sound intensity I given by the equation

60dB = 10log(\dfrac{I}{I_0} )

where I_0 = 1*10^{-12}W/m^2

solving for I we get:

6 = log(\dfrac{I}{I_0} )

10^6 =\dfrac{I}{1*10^{-12}}

\boxed{I = 1*10^{-6} W/m^2}

Now, when 16 violins are playing the intensity I becomes

{I = 16(1*10^{-6} W/m^2)

which on the decibel scale gives

dB = 10log(\dfrac{16*10^{-6}}{1*10^{-12}} )

dB = 72.04\: dB.

Thus, playing 16 violins together gives the intensity level of 72 dB.
