17 Οκτ 2024 · Sound, a mechanical disturbance from a state of equilibrium that propagates through an elastic material medium. A purely subjective, but unduly restrictive, definition of sound is also possible, as that which is perceived by the ear. Learn more about the properties and types of sound in this article.
28 Δεκ 2020 · Sound is a type of mechanical wave or an oscillation of matter. When a sound wave propagates through a medium, such as air, it does so by causing the air molecules to vibrate, which causes changes in air pressure. The speed of sound in air is around 343 m/s but can vary with temperature.
acoustics, the science concerned with the production, control, transmission, reception, and effects of sound. The term is derived from the Greek akoustos, meaning “heard.”
Acoustics is defined by ANSI/ASA S1.1-2013 as "(a) Science of sound, including its production, transmission, and effects, including biological and psychological effects. (b) Those qualities of a room that, together, determine its character with respect to auditory effects."
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. [1]
5 Νοε 2023 · But what exactly is the science behind the sounds we hear? If you’re looking for a quick answer, the study of sound waves and vibrations is known as acoustics or psychoacoustics . In this comprehensive guide, we’ll explore the physics and biology behind sound, including how it’s produced, how our ears interpret it, how it behaves, and the ...
1 Ιαν 2022 · An account of the science of sound and the hearing system. It covers the physical properties of sound, the purpose and evolution of the hearing system, the workings of the mammalian hearing system, sound location, the cocktail party effect and biosonar in bats and whales.
