Ivolumu |

Umsindo ungenye yezimpawu zomsindo; umqondo ophakamayo engqondweni yomuntu mayelana nokuqina noma amandla omsindo lapho ezwa umsindo, ukundindizela kwesitho sokuzwa. I-G. incike ku-amplitude (noma ububanzi bokunyakaza kwe-oscillatory), ebangeni eliya emthonjeni womsindo, emvamisa yomsindo (imisindo yokuqina efanayo, kodwa amafrikhwensi ahlukene abonwa njengehlukile ngokusho kuka-G., ngokufanayo ukuqina, imisindo yerejista ephakathi ibonakala inomsindo kakhulu); ngokuvamile, umbono wamandla omsindo ungaphansi kwe-psychophysiological jikelele. umthetho we-Weber-Fechner (izinzwa ziyashintsha ngokulingana ne-logarithm yokucasuka). Kuma-acoustics omculo ukukala izinga levolumu, kuyisiko ukusebenzisa amayunithi "decibel" kanye "nocingo"; ekuqambeni nasekwenzeni. Umkhuba wase-Italy. amagama athi fortissimo, forte, mezzo-forte, upiyano, pianissimo, njll. asho ngokujwayelekile izilinganiso zamaleveli we-G., kodwa hhayi inani eliphelele lalawa maleveli (i-forte ku-violin, isibonelo, ithule kakhulu kune-forte ye-symphonic orchestra). Bheka futhi i-dynamics.
