Various analog situations in acoustics and electromagnetic waves are described. Certain higher order modes of airborne sound waves in tubes possess a transverse or polarized nature, and ...

Dysphonia is a common condition of abnormal voice production, often caused by problems with the voice box or vocal cords.

A ccording to a new study, we may have been thinking about dolphins’ echolocation all wrong. Rather than using it to “see” ...

This effect, known as diffraction, makes it hard to keep audio contained in one area, particularly with bass-heavy tones. Isolating sound frequencies is even more challenging.

Daniel A. Russell, CC BY-NC-ND Controlling where sound goes is difficult because of a phenomenon called diffraction – the tendency of sound waves to spread out as they travel.

The frequency of these vibrations is what determines pitch. Low frequencies correspond to deep sounds, like a bass drum; high frequencies correspond to sharp sounds, like a whistle. Sound is composed ...

Controlling where sound goes is difficult because of a phenomenon called diffraction —the tendency of sound waves to spread out as they travel. This effect is particularly strong for low-frequency ...
