In this second episode of the "Ask Arline" series, New York City psychologist and noise expert Dr. Arline Bronzaft answers some questions about urban environmental noise.  We cover cars with exceptionally loud engines to people blasting loudspeakers late at night, and bars and clubs with outdoor noise that keeps people awake. Dr. Bronzaft shares some of the solutions that get used in New York, and which might be applicable to other cities as well.
