  2. Diaphragm (acoustics) - Wikipedia

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

    In the field of acoustics, a diaphragm is a transducer intended to inter-convert mechanical vibrations to sounds, or vice versa. It is commonly constructed of a thin membrane or sheet of various materials, suspended at its edges.

  3. Acoustic attenuation - Wikipedia

    en.wikipedia.org/wiki/Acoustic_attenuation

    In acoustics, acoustic attenuation is a measure of the energy loss of sound propagation through an acoustic transmission medium. Most media have viscosity and are therefore not ideal media. When sound propagates in such media, there is always thermal consumption of energy caused by viscosity.

  4. Attenuation - Wikipedia

    en.wikipedia.org/wiki/Attenuation

    The attenuation in the signal of ground motion intensity plays an important role in the assessment of possible strong groundshaking. A seismic wave loses energy as it propagates through the earth (seismic attenuation). This phenomenon is tied into the dispersion of the seismic energy with the distance. There are two types of dissipated energy:

  5. Artifact (error) - Wikipedia

    en.wikipedia.org/wiki/Artifact_(error)

    Sonic artifact, in sound and music production, sonic material that is accidental or unwanted, resulting from the editing of another sound. Visual artifact, in imaging, any unwanted visual alteration introduced by the imaging equipment. Compression artifact, in computer graphics, distortion of media by the data compression.

  6. Attenuator (electronics) - Wikipedia

    en.wikipedia.org/wiki/Attenuator_(electronics)

    Attenuation expressed in decibels of relative power. A 3 dB pad reduces power to one half, 6 dB to one fourth, 10 dB to one tenth, 20 dB to one hundredth, 30 dB to one thousandth and so on. A 3 dB pad reduces power to one half, 6 dB to one fourth, 10 dB to one tenth, 20 dB to one hundredth, 30 dB to one thousandth and so on.

  7. Acoustic reflex - Wikipedia

    en.wikipedia.org/wiki/Acoustic_reflex

    The acoustic reflex (also known as the stapedius reflex, [1] stapedial reflex, [2] auditory reflex, [3] middle-ear-muscle reflex (MEM reflex, MEMR), [4] attenuation reflex, [5] cochleostapedial reflex [6] or intra-aural reflex [6]) is an involuntary muscle contraction that occurs in the middle ear in response to loud sound stimuli or when the person starts to vocalize.

  8. Sound attenuator - Wikipedia

    en.wikipedia.org/wiki/Sound_attenuator

    A sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces.

  9. Sonic artifact - Wikipedia

    en.wikipedia.org/wiki/Sonic_artifact

    Often an artifact is deliberately produced for creative reasons. For example to introduce a change in timbre of the original sound or to create a sense of cultural or stylistic context. A well-known example is the overdriving of an electric guitar or electric bass signal to produce a clipped , distorted guitar tone or fuzz bass .
