The sound intensity from a jackhammer breaking concrete is at a distance of 2m from the point of impact. This is sufficiently loud to cause permanent hearing damage if the operator doesn't wear ear protection.what is the sound intensity an intensity level for a person watching from 50 m away?

A woman stands a distance d from a loud motor that emites sounds uniformly in all directions. The sound intensity of her position is an uncomfortable 2.4 x 10 to the negative third w per m squared. At a distance 3.9 times as far from the motor what are the sound intensity and B the sound intenisty level relative to the threshold of hearing

A trumpet creates a sound intensity level of 1.15 × 102 dB at a distance of 1.00 m. (a) What is the sound intensity of a trumpet at this distance? (b) What is the sound intensity of five trumpets at this distance? (c) Find the sound intensity of five trumpets at the location of the first row of an audience, 8.00 m away, assuming, for simplicity, the sound energy propagates uniformly in all directions. (d) Calculate the decibel level of the five trumpets in the first row. (e) If the trumpets are being played in an outdoor auditorium, how far away, in theory, can their combined sound be heard? (f) In practice, such a sound could not be heard once the listener was 2-3 km away. Why can’t the sound be heard at the distance found in part (e)? Hint: In a very quiet room the ambient sound intensity level is about 30 dB.

A train sounds its horn as it approaches an intersection. The horn can just be heard at a level of 50 dB by an observer 10 km away. What intensity level of the horn’s sound is observed by someone waiting at an intersection 50 m from the train? Treat the horn as a point source and neglect any absorption of sound by the air.
