The study of sound should begin with the properties of sound waves. There are two basic types of wave, transverse and longitudinal, differentiated by the way in which the wave is propagated.

acoustics, the science concerned with the production, control, transmission, reception, and effects of sound. The term is derived from the Greek akoustos, meaning “heard.”

sound, Mechanical disturbance that propagates as a longitudinal wave through a solid, liquid, or gas. A sound wave is generated by a vibrating object. The vibrations cause alternating compressions …

Sound travels in waves that are disturbances that move through a medium by causing particles to vibrate back and forth.

The origin of the science of acoustics is generally attributed to the Greek philosopher Pythagoras (6th century bc), whose experiments on the properties of vibrating strings that produce pleasing musical …

Sound - Frequency, Wavelength, Absorption: In addition to the geometric decrease in intensity caused by the inverse square law, a small part of a sound wave is lost to the air or other medium through …

Jan 16, 2026 · Sounds are produced when vibrating objects, such as the plucked string of a guitar, produce pressure pulses of vibrating air molecules, better known as sound waves.

The loudness of sound as perceived by human ears is roughly proportional to the logarithm of sound intensity: when the intensity is very small, the sound is not audible; when it is too great, it becomes …

In air at a temperature of 70° F (21° C) sound travels at a speed of 1,129 feet (344 meters) per second. This means that it takes sound about five seconds to travel one mile. In warmer air sound travels …

Sound - Frequency, Amplitude, Decibels: The idea of noise is fundamental to the sound of many vibrating systems, and it is useful in describing the spectra of vocal sibilants as well.
