Answer:
<em>6.02 dB increase </em>
<em></em>
Explanation:
Let us take the initial power from the speaker P' = P Watt
then, the final power P = 4P Watt
for a given unit area, initial intensity (power per unit area) will be
I' = P Watt/m^2
and the final quadrupled sound will produce a sound intensity of
I = 4P Watt/m^2
Increase in loudness is gotten from the relation
ΔL =
where
I = final sound intensity
I' = initial sound intensity
imputing values of the intensity into the equation, we have
==>
=
= <em>6.02 dB increase </em>
