Igishushanyo cya Acoustic kireka abakinnyi bambara“na terefone”

Ku ya 6 Kanama 2024 # Imikino Olempike ya Paris # metero 10 yo kwibira kurangira, abatsindiye umudari wa zahabu Quan Hong chan na Chen Yunxi bicaye hamwe, umubiri wabo, usa nkibisanzwe, werekana "umuntu munini wicaye", umutwe mubyukuri uracyambaye na terefone. Abantu benshi bagize icyo bavuga ko aribwo kuruhura imbaraga zo hejuru. Abantu bamwe bibaza: kuki kwambara na terefone mugihe utegereje kuruhuka? Abakunzi benshi batanze igisubizo gikwiye, abakinnyi bategereje kuruhuka kugirango batandukane ikirere cyikibuga, bakomeze kwibanda, kuruhuka, kugabanya impagarara. None, ukurikije imyubakire yububiko bwa acoustique, nkuwashushanyije acoustic, ni ubuhe bwoko bwa acoustique bwibibuga biberamo abantu benshi nka stade nabyo bishobora gufasha abakinnyi?

Dukurikije ibiranga umubiri wa siporo, dushobora gukemura ibibazo bya acoustique duhagarika ibyuma bifata amajwi ahantu hahanamye kandi tugashushanya urukuta rwijwi rwibiti.

Imiterere yimbaho ​​yimbaho ​​ikurura amajwi yujuje ibyangombwa bisabwa hagati yikigereranyo giciriritse kandi gike cyunvikana amajwi, ibyo bigerwaho na acoustic impedance ihuza hamwe nibitekerezo byinshi, kuvunika no kwiyegereza imiraba yijwi. Iyo ijwi ryijwi ryanyuze hejuru yikibaho gikurura amajwi, igice cyijwi ryijwi kizagaragazwa, kandi igice cyijwi ryijwi kizinjira mubutaka, hanyuma kijugunywa nibikoresho byubatswe byubaka. mu kibaho gikurura amajwi, amaherezo uhindure ingufu imbaraga nkeya. Byongeye kandi, substrate yisahani isobekeranye yimbaho ​​irashobora kandi guhitamo MDF ifite imikorere idahumanya neza, cyangwa isahani ya magnesium ikirahure ifite imikorere ihamye yo kutagira amazi, ifite imbaraga zikomeye zidafite amazi, ntabwo byoroshye kubora, no kwinjiza amajwi yayo imikorere irahamye.

Igisenge cya siporo nurufunguzo rwo kunoza amajwi neza. Ijwi ryimyanya yumwanya ryerekana rwose ibice byaryo byose mumajwi yimbere murugo umanitse, kuburyo rifite amajwi menshi yakurura. Umuyoboro wijwi uhuza uhuza imiterere yimbere yijwi ryimbere yinjizamo ipamba hamwe na resonance yimiterere kugirango yinjize amajwi kandi igabanye urusaku, rushobora kugabanya igihe cyo kwisubiraho, kunoza neza amajwi, no gukemura ikibazo cyinenge zijwi. nk'amajwi yibanze hamwe na echo.

Igishushanyo cya acoustic cyahujwe n'ikibaho gikurura amajwi hamwe n'umwanya ukurura amajwi yumubiri bikomeza igihe giciriritse cyo kugaruka kwa natatorium kuri 2.0s-3.5s, ibyo bikaba byerekana ijwi ryumvikana kandi ryumvikana ryamajwi yimyitozo ngororamubiri nibikorwa bya siporo kurwego runini , kandi itezimbere amajwi yuzuye hamwe no kumva umwanya wabasifuzi nabasemuzi.
