  3. Pure tone - Wikipedia

    en.wikipedia.org/wiki/Pure_tone

    [4] [5] In Ohm's acoustic law, later further elaborated by Helmholtz, musical tones are perceived as a set of pure tones. The percept of pitch depends on the frequency of the most prominent tone, and the phases of the individual components is discarded. This theory has often been blamed for creating a confusion between pitch, frequency and pure ...

    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 ]

  6. Acoustic wave - Wikipedia

    en.wikipedia.org/wiki/Acoustic_wave

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

    en.wikipedia.org/wiki/Acoustic_wave_equation

    In physics, the acoustic wave equation is a second-order partial differential equation that governs the propagation of acoustic waves through a material medium resp. a standing wavefield. The equation describes the evolution of acoustic pressure p or particle velocity u as a function of position x and time t. A simplified (scalar) form of the ...

    en.wikipedia.org/wiki/Acoustical_measurements...

    Analysis of sound and acoustics plays a role in such engineering tasks as product design, production test, machine performance, and process control. For instance, product design can require modification of sound level or noise for compliance with standards from ANSI, IEC, and ISO. The work might also involve design fine-tuning to meet market ...
