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 ...

In contrast, the effects of two diametrically opposed mesoscale eddies on sound wave propagation have not been directly measured. The northeast South China Sea has a high probability of developing ...

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.

Underwater waves could also be used to reduce the risks of tsunamis and to improve their early warning systems.

These band gaps prevent the propagation of sound waves within specific frequency ranges. By engineering the phononic crystal structure, scientists can manipulate the flow of sound, create acoustic ...

These crystals provide the highest level of control over phonon propagation and can be designed to have complete ... researchers can create devices that selectively transmit or reflect sound waves of ...
