Kuma-acoustics, kukhona:

1) okuqhubekayo phezu kwe-spectrum, ehlanganisa lonke uhla oluzwakalayo, okuthiwa. umhlophe sh.;

2) umsakazo we-broadband - i-low-frequency, medium-frequency, high-frequency;

3) ibhande elincane, okuthiwa. umbala, Sh. Izibhakela eziningi. izinsimbi zikhipha i-broadband SH: isib. isigubhu esikhulu – imvamisa ephansi, isigubhu esiwugibe – i-mid-frequency, unxantathu – imvamisa ephezulu; emsindweni we-timpani, izigaba zomsindo webhande elincane zihlukaniswa nokugqama kwe-c.-l. iphimbo elilodwa. Sh. kulezi zinsimbi kuphakama mayelana yinkimbinkimbi yokucushwa komzimba oscillating, i-heterogeneity yokwenziwa kwayo. I-Sh., njengomthetho, iyingxenye ebalulekile (kanye namathoni ayingxenye) yomsindo we-muses. amathuluzi anephimbo elichaziwe: isib. kwe fp. Sh. kubangelwa ukundindizela kwenduku nekhanda lesando, futhi kunqunywa ukuqina kwezintambo. ikakhulukazi kurejista ephansi; ku-violin - ukuklebhuka, ukugedla komnsalo, ukudlidliza kwe-torsional. ukunyakaza kwentambo; emtshingoni, emapayipini e-labial esitho - ngokudlidliza okufana ne-vortex yomfudlana womoya onqanyulwe yi-labium. Ekhulwini lama-20 isifiso sokuhlukanisa umsindo womculo wezinsimbi ngokwethula izinsimbi ezintsha, kuhlanganise nomculo okhethekile womculo kagesi, sakhula. amadivaysi; ubuhlakani bokuhlola buvele. izinkomba ezisebenzisa kabanzi i-Sh., isibonelo. ukuhlukumeza, umculo okhonkolo, umculo we-elekthronikhi, umculo we-timbre, i-sonoristics (bona i-Sonorist), njll.
