  2. Sound power - Wikipedia

    en.wikipedia.org/wiki/Sound_power

    Sound power or acoustic power is the rate at which sound energy is emitted, reflected, transmitted or received, per unit time. [1] It is defined [2] as "through a surface, the product of the sound pressure, and the component of the particle velocity, at a point on the surface in the direction normal to the surface, integrated over that surface."

  3. Bass trap - Wikipedia

    en.wikipedia.org/wiki/Bass_trap

    A typical bass trap. Bass traps are acoustic energy absorbers which are designed to damp low-frequency sound energy with the goal of attaining a flatter low-frequency (LF) room response by reducing LF resonances in rooms.

  4. Room modes - Wikipedia

    en.wikipedia.org/wiki/Room_modes

    The input of acoustic energy to the room at the modal frequencies and multiples thereof causes standing waves. The nodes and antinodes of these standing waves result in the loudness of the particular resonant frequency being different at different locations of the room. These standing waves can be considered a temporary storage of acoustic ...

  5. Sound intensity - Wikipedia

    en.wikipedia.org/wiki/Sound_intensity

    Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area, also called the sound power density and the sound energy flux density. [2] The SI unit of intensity, which includes sound intensity, is the watt per square meter (W/m 2).

  6. Room acoustics - Wikipedia

    en.wikipedia.org/wiki/Room_acoustics

    Room acoustics is a subfield of acoustics dealing with the behaviour of sound in enclosed or partially-enclosed spaces. The architectural details of a room influences the behaviour of sound waves within it, with the effects varying by frequency.

  7. Acoustics - Wikipedia

    en.wikipedia.org/wiki/Acoustics

    A transducer is a device for converting one form of energy into another. In an electroacoustic context, this means converting sound energy into electrical energy (or vice versa). Electroacoustic transducers include loudspeakers, microphones, particle velocity sensors, hydrophones and sonar projectors. These devices convert a sound wave to or ...

  8. Absorption (acoustics) - Wikipedia

    en.wikipedia.org/wiki/Absorption_(acoustics)

    The energy transformed into heat is said to have been 'lost'. [1] When sound from a loudspeaker collides with the walls of a room, part of the sound's energy is reflected back into the room, part is transmitted through the walls, and part is absorbed into the walls. Just as the acoustic energy was transmitted through the air as pressure ...

    dwightyoakamacoustic.net is the tenth studio album released in 2000 by American country music artist Dwight Yoakam.It features 25 of his songs recorded in an acoustic manner, save for "Little Sister" which also features Pete Anderson on electric guitar.
