Answer:

X=24.1decibels

Step-by-step explanation:

From the question we are told that:

Loudness function L= 10 log_{10} R

Sound of a person S_p=80\ decibels\ or 10^8

Number of persons talking n=20 people

 

Generally the Relative intensity for 20 people is mathematically given by

Relative intensity forR_{20}=20*10^8

Relative intensity forR_{20}=20^8

Generally the loudness for 20 people is mathematically given by

L_{20}= 10 log_{10} R

L_{20}= 10 log_{10} 20^8

L_{20}= 10 (8 log_{10} 20)

L_{20}= 104.1 decibels

Therefore increase in loudness X is given as

X=104.1-80=-52.90

X=24.1decibels
