2021年3月5日 — The equation that gives an approximation of sound power from the sound pressure of a noise source is: Lw = Lp + 10*LOG(A/A 0 ) https://www.wkcgroup.com Sound and Acoustics: Sound Power Level
Sound and Acoustics: Sound Power Level. Sound power level is a measure of the rate at which acoustic energy is radiated from a sound source. https://engcourses-uofa.ca Sound power measurement
When the sound source is placed over two acoustically reflective planes, the measurement surface is expressed as S=2(2ab+bc+2ac) S = 2 ( 2 a b + b c + 2 a c ) . https://training.dewesoft.com |
