NASA’s X-59 aircraft is predicted to produce a significantly quieter cruise sonic boom than traditional [Formula: see text]-wave-producing aircraft. A propagation simulation study was undertaken to quantify loudness levels, exposure size, and varia

This study examines the behavior of secondary sonic booms on United States (U.S.) coastlines to have a more complete understanding of the impact of supersonic travel on communities. Secondary sonic booms occur when the atmospheric conditions are such

Natural quiet and the sounds of nature are important natural resources and experiencing them is an important aspect of outdoor recreation experiences. Anthropogenic sound can negatively impact these resources and diminish the benefits realized from o

Droplet microfluidics allows one to address the ever-increasing demand to screen large libraries of biological samples. Absorbance spectroscopy complements the golden standard of fluorescence detection by label free target identification and providin

Atmospheric turbulence is known to randomly distort the “N-wave” sonic boom signature emitted by conventional, unshaped supersonic aircraft. To predict the effect of turbulence on the signature from shaped aircraft, a numerical model has been dev

We congratulate the Perseverance rover team for measuring a dust devil and other sounds on Mars. This is a great achievement, and at the same time just a beginning. The acoustics community needs to apply itself to the situations that might come up wh

This presentation describes how secondary sonic booms have influenced our understanding of appropriate coastal buffer distances for supersonic aircraft. The International Civil Aviation Organization issued its Circular 126 in 1975 after the completio

A numerical model of full-scale N-wave sonic boom propagation through turbulence is described based on the nonlinear Khokhlov–Zabolotskaya–Kuznetzov (KZK) propagation equation and the most advanced turbulence model used in atmospheric acoustics.

The topic of supersonic flight over land is being investigated by scientists and regulators alike. The study of how the sonic boom behaves in and around buildings is of particular interest because of the potential impact of the noise on humans. This
