Sound modeling

Chinyorwa ichi chakanangana nenyaya yemagudzanzwi. Isu tichaedza kubvisa ngano zhinji pamusoro padzo uye totsanangura kuti zvitaurisa zvipi chaizvo, zvechinyakare uye izvo zvine mukana weacoustic beam modelling.

Chekutanga, ngatitangei mamwe ekutanga electroacoustics tsananguro dzatichashanda pazviri muchinyorwa chino. Loudspeaker imwe chete electro-acoustic transducer iyo yakaiswa mudzimba. Mubatanidzwa wemagudzanzwi akati wandei mune imwe imba unogadzira seti yegudzanzwi. Rudzi rwakakosha rwegudzanzwi magudzanzwi.

Chii chinonzi gudzanzwi?

Gudzanzwi nderevanhu vazhinji chero mutauri anoiswa mudzimba, asi hachisi chokwadi zvachose. Koramu yegudzanzwi chinhu chakananga chegudzanzwi, icho mudzimba mayo chine akati wandei kusvika gumi nemaviri kana kuti mamwe emagetsi-acoustic transducer (matauri) akarongwa akatwasuka. Nekuda kwechimiro ichi, zvinokwanisika kugadzira sosi ine zvivakwa zvakafanana kune mutsara sosi, hongu kune imwe frequency renji. Iyo acoustic parameters yechitubu chakadaro inoenderana zvakananga nekukwirira kwayo, nhamba yevatauri vakaiswa mairi uye kureba pakati pevashanduri. Tichaedza kutsanangura musimboti wekushanda kwechigadzirwa ichi, pamwe nekutsanangura musimboti wekushanda kwemakoramu ari kuwedzera kufarirwa ane digitally controlled acoustic beam.

Ndezvipi zvitauriri zvinonzwika zvekuenzanisira?

Magudzanzwi achangobva kuwanikwa pamusika wedu ane sarudzo yekuenzanisa iyo acoustic beam. Hurukuro uye chitarisiko chakafanana chaizvo neyechinyakare masipika, anozivikanwa uye akashandiswa kubva kumaXNUMXs. Magudzanzwi anodzorwa nedhijitari anoshandiswa mukumisikidzwa kwakafanana sevanotangira analog. Rudzi urwu rwemichina yegudzanzwi inogona kuwanikwa, pakati pezvimwe, mumachechi, panokwirirwa vafambi pazviteshi zvechitima kana nhandare dzendege, nzvimbo dzeveruzhinji, matare uye mahoro emitambo. Nekudaro, kune akawanda maficha ayo anodzorwa nedhijitari acoustic danda makoramu anopfuura echinyakare mhinduro.

Nokushandisa magudzanzwi nenzira iyi, tinogona kuswedera pedyo ne "shower" effect, apo, kuenda mberi kwehuwandu hwegudzanzwi rakadaro (nzvimbo yekuparadzira ndiyo imba yekoromo), inzwi rezwi rinodonha zvakanyanya. Neiyi nzira, iyo inoratidzirwa nhanho yenzwi inogona kudzikiswa, ichiwana kuvandudzwa kukuru mukunzwisisa kwekutaura.

Mumazuva iwayo emagetsi akagadzirwa zvikuru, tinosangana nemhinduro dzakawanda uye dzinowanzogadziriswa, izvo, zvisinei, zvinoshandisa fizikisi imwechete iyo yakawanikwa uye yakatsanangurwa kare kare. Digitally modeled ruzha runotipa zvinoshamisa mikana yekujaira kumakamuri akaomarara.

Vagadziri vari kutozivisa budiriro mukutonga kwenzwi uye manejimendi, imwe yemazwi akadaro kutaridzika kwezvitaurisa zvitsva zvizere (modular IC2 naRenkus-Heinz), iyo inogona kuiswa pamwechete munzira chero ipi zvayo kuwana yemhando yepamusoro ruzha sosi, inokwenenzverwa zvakazara uku iri mutsara sosi uye poindi.
