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

Sound is a vibration that travels through air as a wave. These waves are created when an object moves back and forth, ...

What is sound? Sound is a vibration that travels through air as a wave. These waves are created when an object moves back and forth, compressing and decompressing air molecules. The frequency of these ...

THE modified form of the ionic deflexion theory of wave propagation, discussed by Messrs. Nichols and Schelling (NATURE, March 7, vol. 115, p. 334), appears to have been suggested in England and ...

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, ...

For the first time, MIT scientists have successfully imaged how heat actually travels in a wave, known as a “second sound,” through this exotic fluid. Understanding this dynamic could help ...

AMONG the facts to be explained in a satisfactory theory of the propagation of radio waves over the earth's surface are the curvature of the rays in transmission between stations far apart ...

Air vibrates back and forth within the neck, creating sound waves of a frequency that depends on the volume of the cavity and the dimensions of the neck and opening. When a person claps their ...

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 capture the imagery, NASA used ground telescopes with special filters that detect air distortions, such as shock waves, around the supersonic aircraft. On Jan. 28, the aircraft broke the sound ...

A newly released image shows the sound barrier being broken on February ... ground used Schlieren photography to capture the shock waves around Boom Supersonic’s demonstrator aircraft XB-1 ...
