  2. Sound - Wikipedia

    en.wikipedia.org/wiki/Sound

    Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an acoustician , while someone working in the field of acoustical engineering may be called an acoustical engineer . [ 3 ]

    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.

  4. Auditory system - Wikipedia

    en.wikipedia.org/wiki/Auditory_system

    Auditory system. Auditory system. Anatomical terminology. [ edit on Wikidata] How sounds make their way from the source to the brain. The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system. [ 1]

  5. Vocal cords - Wikipedia

    en.wikipedia.org/wiki/Vocal_cords

    In essence, sound is generated in the larynx by chopping up a steady flow of air into little puffs of sound waves. [29] The perceived pitch of a person's voice is determined by a number of different factors, most importantly the fundamental frequency of the sound generated by the larynx. The fundamental frequency is influenced by the length ...

  6. Acoustic wave - Wikipedia

    en.wikipedia.org/wiki/Acoustic_wave

    Acoustic wave is a mechanical wave that transmits energy through the movements of atoms and molecules. Acoustic wave transmits through fluids in longitudinal manner (movement of particles are parallel to the direction of propagation of the wave); in contrast to electromagnetic wave that transmits in transverse manner (movement of particles at a right angle to the direction of propagation of ...

  7. Sonochemistry - Wikipedia

    en.wikipedia.org/wiki/Sonochemistry

    In chemistry, the study of sonochemistry is concerned with understanding the effect of ultrasound in forming acoustic cavitation in liquids, resulting in the initiation or enhancement of the chemical activity in the solution. [1] Therefore, the chemical effects of ultrasound do not come from a direct interaction of the ultrasonic sound wave ...

  8. Acoustic resonance - Wikipedia

    en.wikipedia.org/wiki/Acoustic_resonance

    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 frequencies ). The term "acoustic resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since acoustics is defined in ...

  9. Absorption (acoustics) - Wikipedia

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

    In acoustics, absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy. Part of the absorbed energy is transformed into heat and part is transmitted through the absorbing body. The energy transformed into heat is said to have been ' lost '.
