Problem 27

A train sounds its horn as it approaches an intersection.The horn can just be heard at a level of 50 dB by anobserver 10 km away. (a) What is the average power generatedby the horn? (b) What intensity level of the hornssound is observed by someone waiting at an intersection50 m from the train? Treat the horn as a point sourceand neglect any absorption of sound by the air.
