CSDA was selected for the Airport Cooperative Research Program (ACRP) study 02-51 to evaluate methods for determining interior noise levels used in airport sound insulation programs nationwide. Our team of expert researchers is evaluating acoustical measurement methods employed in FAA-sponsored airport sound insulation programs, including: aircraft flyover, elevated exterior loudspeaker, ground level exterior loudspeaker, indoor loudspeaker and sound intensity.
The objectives of this research are to: (1) identify and evaluate the accuracy of noise level reduction (NLR) measurement methods; (2) propose procedures to minimize the measurement inaccuracies of each method; and (3) develop a matrix to help program sponsors identify the most appropriate methodology for determining interior noise levels for their airport sound insulation program.
CSDA is working with the following consultants on this study:
Dr. Paul Schomer, PE – Schomer and Associates
John Freytag, PE – Freytag & Associates, LLC
Herbert Singleton, PE – Cross-Spectrum Acoustics LLC
