I-Resonance |

I-French resonance, kusukela ku-lat. resono - ngizwakala ngiphendula, ngiyaphendula

Isenzakalo se-acoustic lapho, ngenxa yethonya lokudlidliza komzimba owodwa, okubizwa ngokuthi i-vibrator, komunye umzimba, okubizwa ngokuthi i-resonator, ukudlidliza okufana nemvamisa nokuvala kwe-amplitude kwenzeka. I-R. ibonakala ngokugcwele ngaphansi kwezimo zokucushwa okunembayo kwe-resonator ukuya kufrikhwensi yokudlidliza yesidlidlizi kanye nokuhle (ngokulahlekelwa amandla aphansi) ukudluliswa kokudlidliza. Lapho ucula futhi wenza emculweni. I-R. isetshenziselwa izinsimbi zokukhulisa umsindo (ngokufaka indawo enkulu yomzimba we-resonator ekudlidlizeni), ukushintsha i-timbre, futhi ngokuvamile ukwandisa ubude besikhathi somsindo (njengoba i-resonator ku-vibrator-resonator. Uhlelo alusebenzi nje kuphela njengomzimba oncike kusidlidlizi, kodwa futhi njengomzimba ozimele oscillating, one-timbre yawo nezinye izici). Noma iyiphi i-vibrator ingasebenza njenge-resonator, noma kunjalo, ekusebenzeni, okukhethekile kuklanyelwe. ama-resonators, alungile ezicini zawo futhi ahambisana nezidingo zomculo. izidingo zensimbi (ngokwephimbo, ivolumu, i-timbre, ubude besikhathi somsindo). Kukhona ama-resonator angawodwa aphendula imvamisa eyodwa (indawo yokumisa yemfoloko ezwakalayo, i-celesta, amaresonatha e-vibraphone, njll.), namaresonatha amaningi (amadekhi e-fp, amavayolini, njll.). G. Helmholtz usebenzise isenzakalo sika-R. ukuze ahlaziye i-timbre yemisindo. Wachaza ngosizo lukaR. ukusebenza kwesitho somuntu sokuzwa; ngokuvumelana ne-hypothesis yakhe, ebonwa ukushintshashintsha kwendlebe. ukunyakaza kujabulisa kakhulu lawo makhothamo e-Corti (atholakala endlebeni engaphakathi), i-to-rye icushwa imvamisa yomsindo onikeziwe; ngakho, ngokombono kaHelmholtz, umehluko phakathi kwemisindo yephimbo ne-timbre usekelwe ku-R. Igama elithi “R.” evame ukusetshenziswa ngephutha ukukhombisa izici ze-acoustical zezakhiwo (esikhundleni samagama athi “reflection”, “absorption”, “reverberation”, “dispersion”, njll. asetshenziswa kuma-acoustics ezakhiwo).
