A Study in a New Test Facility on Indoor Annoyance Caused by Sonic Booms

| PRODUCT TYPE | Paperback (Paperback) |
Description
A sonic-boom simulator at NASA Langley Research Center has been constructed to research the indoor human response to low-amplitude sonic booms. The research goal is the development of a psychoacoustic model for individual sonic booms to be validated by future community studies. The study in this report assessed the suitability of existing noise metrics for predicting indoor human annoyance. The test signals included a wide range of synthesized and recorded sonic-boom waveforms. Results indicated that no noise metric predicts indoor annoyance to sonic-boom sounds better than Perceived Level, PL. During the study it became apparent that structural vibrations induced by the test signals were contributing to annoyance, so the relationship between sound and vibration at levels of equivalent annoyance has been quantified. Rathsam, Jonathan and Loubeau, Alexandra and Klos, Jacob Langley Research Center NASA/TM-2012-217332, L-20108, NF1676L-14072
