Web27 Apr 2024 · Speaker sensitivity is a measure of how loud a speaker will play at a given input power or at a given input voltage. Sensitivity is normally measured with a 1 watt power input or a 2.83 Vrms voltage input. The acoustic output is normally measured in an anechoic space at a distance of 1 meter from the speaker. http://resource.npl.co.uk/acoustics/techguides/concepts/siunits.html WebSPL is proportional to the average squared pressure amplitude. ``Threshold of audibility'': 0 dB SPL; ``Threshold of Pain'': 120 dB SPL In a free field, pressure varies as for an omni-directional source. This corresponds to a 6 dB decrease in SPL for each doubling of distance from the source. Sound Power pharm allait

Sound pressure or acoustic pressure is the local pressure deviation from the ambient (average or equilibrium) atmospheric pressure, caused by a sound wave. In air, sound pressure can be measured using a microphone, and in water with a hydrophone. The SI unit of sound pressure is the pascal (Pa). See more A sound wave in a transmission medium causes a deviation (sound pressure, a dynamic pressure) in the local ambient pressure, a static pressure. Sound pressure, denoted p, is defined by • ptotal … See more When measuring the sound pressure created by a sound source, it is important to measure the distance from the object as well, since the sound pressure of a spherical sound wave decreases as 1/r from the centre of the sphere (and not as 1/r , like the sound … See more • Acoustics • Phon (unit) • Loudness • Sone (unit) See more Sound intensity In a sound wave, the complementary variable to sound pressure is the particle velocity. Together, they determine the sound intensity of the wave. Sound intensity, denoted I and measured in See more Sound pressure level (SPL) or acoustic pressure level is a logarithmic measure of the effective pressure of a sound relative to a reference value. Sound pressure level, denoted Lp and measured in dB, is defined by: • p … See more • Media related to Sound pressure at Wikimedia Commons • Sound Pressure and Sound Power, Effect and Cause See more WebSound Power (W) Sound power is the energy rate, or energy of sound per unit of time ( J/s or W in SI-units) - emitted by a source. When sound propagates through a medium acoustic sound power is transferred. The sound intensity is the sound power transmission through a surface (W/m2) - a vector quantity with direction through a surface.
