There is no difference in principle between the infrasonic and ultrasonic sounds, which are inaudible to humans (or other animals) and the sounds that we can hear. In all cases, sound is a wave of pressure and particle oscillations propagating through an elastic medium, such as air.

The Journal of the Acoustical Society of America, 1945
An asymptotic expansion has been derived from a formula given by W. N. Brown, which allows the plotting of directional and response curves for a vibrating cone in an infinite baffle. The results are compared with those pertaining to a flat disk of same radius.

Sources of Underwater Sound and Their Characterization
2016Because of the history of sonar and sonar engineering, the concept of "source level" is widely used to characterize anthropogenic sound sources, but is it useful for sources other than sonar transmitters? The concept and applicability of source level are reviewed for sonar, air guns, explosions, ships, and pile drivers. International efforts toward the

Sound-source localization when listeners and/or sound sources move
The Journal of the Acoustical Society of America, 2021In the dynamic everyday world, sound sources and/or listeners move when animals attempt to localize sound sources. Determining sound-source locations in these dynamic scenarios requires several computations by the brain. The auditory-spatial cues (Interaural Time Differences, ITDs; Interaural Level Differences, ITDS; and spectral cues associated with ...

Sound Source Separation Apparatus And Sound Source Separation Method
The Journal of the Acoustical Society of America, 2011To shorten an output delay while a high sound source separation performance is ensured when a sound separation process based on an ICA method is performed. A second Fourier transform process execution cycle t2 for obtaining a second frequency-domain signal S1 used as an input signal of a filter process is set shorter than a first Fourier transform ...

According to Lighthill’s theory, one may distinguish sound sources in a free flow in terms of monopoles, dipoles, and quadrupoles [1]. The volume flow itself is irrelevant for monopole sound generation. It is the variation in time of the volume determined by the fluctuating mass flow, which generates sound.
