Answer:
the noise level of 5400 flies is equal to 84.32 dB
Explanation:
Noise made by house flies = 47 dB from the distance of 2.4 m
to calculate the noise of 5400 flies at a distance of 2.4 m.
the intensity of noise
now, I' = 5400 I₀
= 
= ![10 [log_{10}[5400] +log_{10}(\dfrac{I}{I_0}))](https://tex.z-dn.net/?f=10%20%5Blog_%7B10%7D%5B5400%5D%20%2Blog_%7B10%7D%28%5Cdfrac%7BI%7D%7BI_0%7D%29%29)
= 10 ( 3.732 + 4.7 )
= 84.32 dB
hence, the noise level of 5400 flies is equal to 84.32 dB
