Download or read book House Noise Reduction Measurements for Use in Studies of Aircraft Flyover Noise written by A-21 Aircraft Noise Measurement Aviation Emission Modeling and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document is not currently used for regulatory purposes but is useful for researchers and students. However, it contains useful measurement data for homes built prior to 1970 including 1/3 octave transmission loss data. This document should be stabilized to maintain those data. In addition, FAA and A-21 are currently working on an updated method for doing these tests.

This book was released on 2016 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides guidance for selecting and implementing methods for measuring noise level reduction in dwellings associated with airport noise insulation programs. The research complements the results of ACRP Report 89: Guidelines for Airport Sound Insulation Programs and was undertaken to assess the accuracy and validity of various noise level reduction measurement procedures currently used in airport noise insulation programs. Acoustical field measurements were made at 10 homes near San Diego International Airport and nine homes near Boston Logan International Airport. Seven measurement methods were tested: outdoor ground-level artificial sound source (loudspeaker); outdoor elevated artificial source (loudspeaker); indoor artificial sound source (loudspeaker); aircraft flyover: fixed microphone; aircraft flyover: moving microphone; architectural survey and noise reduction calculations; and acoustic intensity measurements, exterior loudspeaker and interior intensity. The report includes a summary of sound insulation theory and the science behind noise level reduction, and an overview of FAA-sponsored noise insulation programs. The report also provides guidance, including a decision matrix, for selecting an appropriate acoustical testing method. Lastly, the report provides suggested practices for each measurement technique, based on the results of the research.

Download or read book Atmospheric absorption Adjustment Procedure for Aircraft Flyover Noise Measurements written by Alan H. Marsh and published by . This book was released on 1977 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical method was developed for adjusting measured aircraft noise levels for differences in atmospheric absorption between test and reference meteorological conditions along the sound propagation path. The method is based on the procedure in the proposed American National Standard ANS S1.26 for calculating pure-tone sound absorption as a function of the frequency of the sound and the temperature, humidity, and pressure of the air. Measured aircraft noise levels are assumed to be 1/3-octave-band sound pressure levels. A computer program was written in FORTRAN IV to carry out the calculations. The operation of the computer program, the required input data, and all symbols and terms used in the program are described. A program listing of source statements is provided. Recommendations are given for applying the method to routine processing of aircraft noise measurements. (Author).
