I detta avsnitt beskriver och f\u00f6rklara vi fem olika typer av ljudabsorbenter, hur ljudabsorbenter fungerar, deras unika egenskaper och hur de relaterar till Gustafs produktsortiment.

A. Mid-resonansabsorbenter, paneler (Helmholtz)<\/h5>\n

Helmholtz-absorbenter anv\u00e4nds f\u00f6r att reducera mellan-frekvenser. Helmholtz-konstruktionen best\u00e5r av en \u201dkammare\u201d (1) (luftrummet) som st\u00e5r i f\u00f6rbindelse med rummet genom en \u201dnacke\u201d (2) (perforeringsh\u00e5l). Luften i nacken p\u00e5verkas av ljud och s\u00e4tter luften i kammaren i resonans, vilket omvandlar ljudenergin till v\u00e4rmeenergi. Ljudabsorptionen \u00f6kar om avst\u00e5ndet till v\u00e4ggen, och d\u00e4rmed kammaren\/luftspalten, \u00f6kar. Helmholz-absorbenter fungerar \u00f6ver ett kort spann av frekvenser, men det kan ut\u00f6kas genom att fylla luftrummet med ett por\u00f6st mineral-ull (1) och genom att s\u00e4tta en filt med luftgenomsl\u00e4pp (3) direkt bakom \u201dnacken\u201d.<\/p>\n<\/div>\n <\/div>\n <\/div>\n

Helmholtz-absorbenter anv\u00e4nds f\u00f6r att reducera mellan-frekvenser. Helmholtz-konstruktionen best\u00e5r av en \u201dkammare\u201d (1) (luftrummet) som st\u00e5r i f\u00f6rbindelse med rummet genom en \u201dnacke\u201d (2) (mellanrummet mellan ribborna). Luften i nacken p\u00e5verkas av ljud och s\u00e4tter luften i kammaren i resonans, vilket omvandlar ljudenergin till v\u00e4rmeenergi. Ljudabsorptionen \u00f6kar om avst\u00e5ndet till v\u00e4ggen, och d\u00e4rmed kammaren\/luftspalten, \u00f6kar.

C. Nano-absorbenter (Nano + Helmholtz)<\/h5>\n

Nano-absorbenter anv\u00e4nds f\u00f6r att reducera mellan och mellanh\u00f6ga frekvenser. Nano absorbenter fungerar enligt Helmholtz-mekanismen, men utan behov av den traditionella \u201dkammaren\u201d f\u00f6r att absorbera ljudet. Ljudenergin transformeras ist\u00e4llet till v\u00e4rmeenergi n\u00e4r ljudet tr\u00e4nger igenom den extremt tr\u00e5nga \u201dnacken\u201d (2) h\u00e4r i form av Nano-perforeringsh\u00e5l (300.000\/m\u00b2) med en diameter p\u00e5 endast 0,5 mm. Ljudabsorptionen kommer d\u00e4remot att f\u00f6rb\u00e4ttras n\u00e4r en \u201dkammare\u201d (5) l\u00e4ggs till p\u00e5 panelen, bakom Nano-perforeringslagret och n\u00e4r en filt med luftgenomsl\u00e4pp (3) appliceras bakom panelen. N\u00e4r panelen installeras med ett avst\u00e5nd till mellan v\u00e4ggen eller taket, f\u00f6rslagsvis fyllt med mineral-ull (1), kommer ljudabsorptionen att \u00f6ka ytterligare. N\u00e4r en Nano-panel har installerats enligt ovan kombinerar produkten flertalet akustikmekanismer som ger dig den sv\u00e5rslagna absorptionsklassen B.<\/p>\n<\/div>\n <\/div>\n <\/div>\n

D. Por\u00f6sa absorbenter<\/h5>\n

Por\u00f6sa absorbenter (2) \u00e4r normalt tillverkade av mineral- eller polyester-ull. Por\u00f6sa absorbenter \u00e4r bra p\u00e5 att reducera h\u00f6ga frekvenser. Ljudenergin transformeras till v\u00e4rmeenergi n\u00e4r den tr\u00e4nger igenom ullen tv\u00e5 g\u00e5nger, in och ut. Ljudabsorberingen \u00f6kar om avst\u00e5ndet till v\u00e4ggen, och d\u00e4rmed luftrummet, \u00f6kar. Fylls luftrummet (1) med ull \u00f6kar absorptionen ytterligare.<\/p>\n<\/div>\n <\/div>\n <\/div>\n
