The sound is emitted in a HEMIsphere, total area: 2PI(19.3)^2
assuming it is uniform, the amount just on the ear drum is...the ratio of the the areas of sound power per area.
W(above)*PI(1.7e-2 /2)^2 /(2 PI (19.3^2)) check that.
Part One:
The decibel level of the noise from a jet aircraft
is 130 dB when measured 19.3 m from
the aircraft.
How much sound power does the jet aircraft
emit?
Answer in units of W - 46673.5W
I need help with Part Two:
Part Two:
How much sound power would strike the
eardrum of an airport worker 19.3 m from
the aircraft? (Assume the diameter of the
worker’s eardrum is 1.7 × 10−2m)
