Answer:
The sound level of the point source at a distance of 10 meters is approximately 110.294 decibels.
Step-by-step explanation:
First, we calculate the intensity (
), in watts per square meter, by the Inverse-Square Law:
(1)
Where:
- Power, in watts.
- Radius, in meters.
And the sound intenity level (
), in decibels, is expressed by:
(2)
Where
is the reference sound intensity, in watts per square meter.
If we know that
,
and
, then we find that sound level at a distance of 10 meters is:
The sound level of the point source at a distance of 10 meters is approximately 110.294 decibels.
