Answer:
The correct answer is part 'c' 160 dB
Explanation:
When noise levels of different intensities are superimposed the resultant intensity is given by the equation
where,
is the intensity of a general sound level
Since we have 10000 fans each producing sound of 80dB thus the resultant intensity is given using the above formula as
Answer: The sound intensity was reduced by -14.77 dB.
Explanation:
The level of the intensity of the sound with respect to the reference value is called Sound Intensity level.
I = Intensity of the sound
= Reference sound intensity
According to question, sound-reflecting windows that reduce the sound intensity level by 30.0 db .
Let the intensity of the sound be and reduced intensity be I.
The sound intensity was reduced by -14.77 dB.
