An acoustic amplitude (AA) is sampled during a recording time period (24 ; 64) at a determined position along the tube.

This superposition of solitary waves at the focal point forms the sound bullet—a highly compact, large-amplitude acoustic wave.

The outgoing acoustic wave is arranged to interfere with a bypass part of the acoustic wave to produce a resultant acoustic wave having a reduced amplitude.

The electronic signal applied to an acoustic transducer at each frequency is gradually increased in amplitude to a desired amplitude.

A rotary acoustic horn imparts energy at a selected wavelength, frequency, and amplitude.

A signal transmitted by a sound source (1) is fed to a transducer (3) where the sound signal is transformed into a light signal modulated in amplitude by the sound signal.

The acoustic vibration comprises a carrier wave that is amplitude modulated by an AM waveform.

The acoustical parameter may include a frequency, an amplitude, a phase, modulation, or a time delay.

The inventive method consists in processing the complex amplitude/azimuth spectrum of an acoustic signal received by a directional buoy.

An acoustic amplitude (AA) is sampled during a recording time period (24 ; 64) at a determined position along the tube.

The method can include applying acoustic energy at an amplitude of vibration selected in combination with the frequency of vibration to yield an acoustic velocity of no greater than 4.72 m/s.

A method of manufacturing an acoustical energy transfer component having a component body with a uniformly isotropic expansion and contraction amplitude upon acoustical excitation.

An acoustic horn imparts energy at a selected wavelength, frequency, and amplitude.

natural acoustic space, each reflection’s amplitude and brightness decays over time.

An acoustic source transmits acoustic to an acoustic receiver along an acoustic path.
