Question 5
There is a vibrating point source radiating from a machine, what is
the decreasing
factor of wound intensity when the distance from the source is
doubled? Explain the
results in term of calculation. (8 marks)
Homework Answers
Sound intensity is defined as the power carried by sound waves per unit area in a direction perpendicular to that area.
So, when the distance from the source is doubled, sound intensity will decrease by factor of 1/4
