The TRANSMISSION of acoustic energy through a medium via a SOUND WAVE. See: SOUND, SPEED OF SOUND. Compare: ACOUSTIC RADIATION. The levels of outdoor NOISE, whether they are intrusive or the normal ...

The researchers found solutions to several parts of the equation that mathematically describe the propagation of sound waves using parallel computing on four graphics processors (graphics cards ...

Ten years ago, researchers succeeded in suppressing sound wave propagation in the backward direction; however, this also attenuated the waves traveling forwards. A team of researchers at ETH ...

As a result, researchers are exploring new and novel ways to dial down the volume. They are turning to highly specialized materials and structures designed to buffer, baffle, and block sound waves.

The small black loudspeaker that generated the sound waves can be seen on the ... grating during the experiment to measure the propagation of the waves can be seen on the far right.

The effects described above can be implemented by cancelling the forward characteristics of the linear loudspeaker array, and then overlaying the desired sound-wave propagation characteristics.

Using high-frequency sound waves to make tunable optical filters ... precisely and rapidly control the wavelength, amplitude and propagation direction of a laser beam. These capabilities are ...
