Given information
Given:
Power of the first expensive amplifier 
Power of the less expensive amplifier 
Distance
Formula used:
By dividing the sound power by the area of a circle of radius 
, the sound intensity at a location distance away from a source emitting 
power of sound evenly in all directions may be calculated. As a result, sound intensity
.
The deci Bell is a logarithmic unit used to represent the degree of sound intensity at a certain location. The ratio of sound intensity at a given point to threshold intensity sound is the sound intensity level at that point.
Step-by-step explanation
Step 1.
Sound intensity is measured in terms of power per unit area. Assume that the sound is emitted in a spherical pattern from the loudspeaker.
