Calculation of the Direction of Line AB as a Check Summary. That’s all there is to calculating azimuths. Simply follow a simple rule if going clockwise about the traverse: “Subtract the ...

In 1975, the zoologist Arie Schuijf proposed a model 5 suggesting that fish can localize the direction of a sound source by comparing the associated particle-motion and pressure components of a sound.

One of the fascinating features of human hearing is its ability to localize sound. While the human ear usually does this with binaural cues, it is, in fact, possible to locate sound direction with ...

Sound waves canceled each other out in the unwanted directions, while carrying the sound energy efficiently in the desired direction. This boosted the directivity factor in the speaker system designs.
