Acoustic Ntoo Diffuser

Txhawm rau ua kom lub tsev hais plaub thiab ua yeeb yaj kiab, TV thiab xov tooj cua lub tsev kaw suab studio thiab studio hauv tsev suab paj nruag cov yam ntxwv ntawm cov yam ntxwv, nws cov phab ntsa sab hauv feem ntau tau nruab ib co suab-absorbing phaj, acoustic ntoo diffuser, cov acoustic ntoo diffuser cov khoom thiab cov duab yog ntau yam. ntawm, uas yog feem ntau siv nyob rau hauv daim ntawv ntawm ncig arc kem acoustic ntoo diffuser. Raws li peb plywood yooj yim khoov, nws yuav raug kho nyob rau hauv lub sab hauv phab ntsa ntawm lub voj voog keel, nws tsim ib tug diffusion lub cev, tsis tsuas yog yuav ua rau lub suab nrov diffusion, tab sis kuj muaj peev xwm ua si ib tug tej yam lub luag hauj lwm nyob rau hauv lub suab haum, kuj yog ib tug zoo. ntawm lub cev nqus suab.

Thaum ntsuas cov khoom siv hauv tsev nrog cov coefficient siab nqus, xws li kev nqus dej tshwj xeeb hauv pem teb ntawm li 10m2, qhov sib txawv ntawm lub suab sab hauv tsev tuaj yeem ua rau tsis zoo. Lwm qhov piv txwv yog qhov kev sim ntawm cov suab nrov ntshiab lossis nqaim lub suab nrov lub zog, qhov twg diffusion tsis ua tiav nyob rau hauv qis zaus band vim tias ob peb yam yooj yim zoo vibration hom zoo siab heev. Qhov no yog qhov sib ntxiv ntawm lwm qhov diffuser rau chav tsev yuav tsum xav txog. Feem ntau, lub convex ib nrab-lub tog raj kheej, hemisphere lossis lwm cov duab ntawm diffuser yog tsim rau ntawm phab ntsa lossis qab nthab ntawm chav tsev (tsis tas txhua phab ntsa, tsuas yog ib sab tuaj yeem ua rau ntawm ob sab), thaum lub wavelength ntawm lub suab tsis thiab diffuser loj. zoo sib xws los yog me dua nws, lub diffuser tuaj yeem ua lub luag haujlwm diffusion. Nyob rau tib lub sijhawm, tseem tuaj yeem zam lub suab nrov nrov thiab lwm yam tshwm sim, lub luag haujlwm tseem ceeb ntawm no acoustic ntoo diffuser tsuas yog hloov qhov yooj yim zoo vibration hom ntawm spatial qauv. Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj teeb meem ntxiv rau kev nqus los ntawm resonance ntawm acoustic ntoo diffuser nws tus kheej.
