  2. Sound - Wikipedia

    en.wikipedia.org/wiki/Sound

    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 ]

  3. Acoustic dispersion - Wikipedia

    en.wikipedia.org/wiki/Acoustic_dispersion

    A widely used technique for determining acoustic dispersion is a broadband transmission method. This technique was originally introduced in 1978 and has been employed to study the dispersion properties of metal (1978), epoxy resin (1986), paper materials (1993), and ultra-sound contrast agent (1998).

  4. Acoustic resonance - Wikipedia

    en.wikipedia.org/wiki/Acoustic_resonance

    However, if a piece of metal is placed on a prong, the effect dampens, and the excitations become less and less pronounced as resonance isn't achieved as effectively. Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its resonance ...

  5. Acoustics - Wikipedia

    en.wikipedia.org/wiki/Acoustics

    Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer .

  6. Speeds of sound of the elements - Wikipedia

    en.wikipedia.org/wiki/Speeds_of_sound_of_the...

    The speed of sound in any chemical element in the fluid phase has one temperature-dependent value. In the solid phase, different types of sound wave may be propagated, each with its own speed: among these types of wave are longitudinal (as in fluids), transversal, and (along a surface or plate) extensional. [1]

  7. Speed of sound - Wikipedia

    en.wikipedia.org/wiki/Speed_of_sound

    Sound passes through the system by compressing and expanding the springs, transmitting the acoustic energy to neighboring spheres. This helps transmit the energy in-turn to the neighboring sphere's springs (bonds), and so on. The speed of sound through the model depends on the stiffness/rigidity of the springs, and the mass of the spheres. As ...

  8. Acoustical engineering - Wikipedia

    en.wikipedia.org/wiki/Acoustical_engineering

    Bioacoustics concerns the scientific study of sound production and hearing in animals. It can include: acoustic communication and associated animal behavior and evolution of species; how sound is produced by animals; the auditory mechanisms and neurophysiology of animals; the use of sound to monitor animal populations, and the effect of man ...

  9. Cymatics - Wikipedia

    en.wikipedia.org/wiki/Cymatics

    The sound wave, therefore, does not influence at all the shape of the vibrating body or the shape of the nodal patterns. The only thing that changes due to the vibration is the arrangement of the sand.
