Summary Seismic waves caused by earthquakes radiate infrasound into the atmosphere as they proceed over the Earth's surface. Several instances of such sound waves radiated locally by seismic waves passing through the Washington, D.C., area have been

Summary The physical properties and propagation characteristics of atmospheric infrasound determine the techniques and instrumentation used for its measurement. The physical properties which influence the design of the measurement system for infrasou

The reciprocal theorem of mathematical physics was not originated by Rayleigh. However, the theorem is presented, in several forms, with elegant clarity in his Theory of Sound. Since its publication his book has influenced generations of physicists,

We observe that aircraft produce pressure increases at the surface proportional to the aircraft weight. Measured values are in general agreement with predictions. The time scales are longer for aircraft weight transfer pressure changes (typically 2

The use of an analog acoustic intensity meter to determine the sound power radiated from an open‐ended standing‐wave tube [R. K. Cook and T. M. Proctor, J. Acoust. Soc. Am. 65, 1542–1555 (1979)] is extended to bandlimited random noise. Two micr

An open ended standing‐wave tube has been examined as an absolute sound power (ASP) source, having an absolutely known radiated sound power. The ASP source can serve as an acoustical instrument, principally in reverberation chambers, for three purp

Underwater sounds from migrating gray whales were recorded from a bottom‐mounted hydrophone array. Sound‐source locations were based upon arrival‐time differences and received levels. Visual tracking corroborated sound data. Moans were the most
