The film explores the nature of sound waves, demonstrating how sound travels as a wave through air, which acts as a medium. It illustrates sound generation using a loudspeaker, examines oscillation, ...

Introduced in 1946 and 1963, respectively, the Klipschorn and La Scala loudspeakers look unchanged, but feature new drivers ...

Researchers develop virtual sound technology for private listening in Korea Innovative audio technology enables personal ...

In fact, physicists’ picture of the manner of energy propagation in the universe ... When you shout at your friend across a field, say, the sound waves travel through the air between you two ...

Shortwave radio signals (3-30MHz) are highly susceptible to interference from power adapters, fluorescent or LED light ...

Deep water promotes sound wave propagation (spreading out) enabling acoustical sensors — like SURTASS sensors—to detect enemy submarines; however, according to Navy officials, shallow water ...

Sound waves radiated by underwater vehicles in shallow seas are reflected by the sea surface and seabed. Wave propagation in complex environments is often associated with multi-physics fields.

By disrupting the inherent symmetry of sound propagation in space, it’s possible to direct sound waves, optimize sound propagation, and reduce or increase sound scattering, depending on the design of ...

To address these challenges, researchers are exploring new approaches, including metasurfaces—engineered materials that can control wave propagation in unprecedented ... and providing directional ...

However, they can be affected by environmental factors such as temperature, humidity, and dust, which can interfere with the sound wave propagation and lead to inaccurate measurements. Proper ...
