Answer:
26dB
Explanation:
The decibel level β is a calculated by 10log (I/Io)
Where I and Io represent sound intensity
From the question, there's no interference. So
Where I = 4Io (because there are 4 men shouting), so the intensity will be 4 times larger.
β = 10log (I/Io)
β = 10log (4Io/Io)
β = 10log 4
β = 6.020599913279623
β = 6 ---- Approximated
The decibel level = 20 + 6.020599913279623
Decibel Level = 26.020599913279623
Decibel level =26dB --- Approximated
