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
