Abstract |
This report details the strategies evaluated and assesses the experiences encountered in the investigation of noise from air conditioning and refrigeration condensing units in the State of Maryland. Each is designed to provide guidance for other state and local noise programs faced with similar noise problems. Hence, emphasis is placed on the practical aspects of attempting to implement innovative approaches. These included: (1) sample selection, (2) noise measurement survey, (3) implementation of aggressive abatement procedures, (4) development and use of a screening graph for determining acceptability of sound rated outdoor unitary equipment, (5) incorporation of noise control considerations into The Division of Food Control, (6) exploration of an operational curfew, (7) development of an incentive/information program. |
