The Study of Low Frequency Noise Criteria and the Code of Airport Noise Monitoring Report

Absrtact	The low frequency (L.F.) noise complaints are more and more today. The existed noise criteria are not effective to such annoyance. The purpose of this study was to assess the L.F. noise and suggest the noise control criteria to authorities. And study the existed criteria and summit the criteria refined suggestion are also completed. Different national criteria such as Germany, Japan, Denmark, Netherlands for L.F. noise were compared . 100 complaints case have been measured and studied. The sources of suite were cooling tower, air condition etc. The draft of criteria was discussed on the committee. Finally, the L.F. frequency noise criteria ware completed to authorities and will amended in Noise Control Standard article 3 and article 7. The procedure of the L.F. noise assessment specifies how to measure and judge when there is a L.F. complaint. It’s well useful to local authorities to control L.F. noise problem. The study specified the format of airport noise report that the authorities of airport must summit those reports to the local environment authorities each quarter. The draft edition was discussed with CAA officers, Military officers and contractors of noise monitoring system of airports. Incorporated with EPA to modify the existed noise related regulation, such as aircraft noise limit and control, equipments noise control for military service etc. For aircraft noise limit, the study cited the ICAO Environmental Protection Annex 16 third edition 1993 to replace the word description with formula, amend the noise limit for propeller-driven aircrafts by mass and time of application for certificate of airworthiness for the prototype, add the noise evaluation measure of A weighting maximum and sound exposure level, add the noise limit of helicopters. The regulation of equipments noise control for military service was declared for article two by EPA . The study also hold a domestic environment noise meeting for all the environment authorities and the noise experts in Taiwan to share the noise control experience
