Sound­proo ng has a re­mark­able ef­fect on any space, whether it’s your home theatre, record­ing stu­dio or jam room. The chal­lenge is not just to re­tain more of the de­sired sound, but also to block out ex­te­rior noises and en­hance your sound ex­pe­ri­ence.

Ev­ery­one is be­com­ing aware of the need for noise iso­la­tion and sonic pri­vacy. Whether you’re build­ing a home theatre from scratch or ren­o­vat­ing and con­vert­ing one of your ex­ist­ing rooms. a thump­ing home theatre may pro­duce up to 100dB+ of sound level — that’s some­where in be­tween a school disco and a rock con­cert!

A stan­dard stud con­struc­tion in­te­rior wall with plas­ter­board on both sides will cut lev­els by only 30-35dB, leav­ing your neigh­bours and loved ones with noise lev­els akin to liv­ing next to a free­way. Adding an ex­tra layer of plas­ter­board is re­mark­ably in­ef­fec­tive — per­haps only an­other cou­ple of dB saved.

Dynil & Dy­na­pad

En­ter the rst two se­crets: Dynil and Dy­na­pad. Th­ese so­lu­tions are from Dy­na­mat, which has a US­man­u­fac­tured range of so­lu­tions used glob­ally for its sound, heat and vi­bra­tion damp­ing ef ciency, and dis­trib­uted in Aus­tralia by Au­diox­tra.

At only 2.5mm thick, Dynil is a wa­ter and oil re­sis­tant ma­te­rial which is eas­ily xed to stud walls, oor­ing sub­strates and var­i­ous ceil­ing struc­tures. For use on wall skins. the prod­uct is sim­ply xed to the stud frame prior to stan­dard plas­ter­board ap­pli­ca­tion and you’re left with a layer that can block up to 40dB. This can be ap­plied to new con­struc­tions or re­stricted to a sin­gle wall face of re­fur­bished spa­ces. Dynil com­plies with re rat­ing stan­dards BELOW: four se­cret weapons to bring noise un­der con­trol and cre­ate a more silent noise oor for your sys­tem to do its stuff... and is re­sis­tant to tem­per­a­ture ex­tremes (-40° to 105°C). In oor or ceil­ing pro les. it can be spanned be­tween rafters/joists and di­rectly on top of or un­der par­ti­cle­board or tim­ber oor­ing.

Dy­na­pad is equally ef cient as a oor sound bar­rier and can also be in­stalled above or below any sound or noise source. With the ad­di­tional oil and wa­ter re­sis­tant thermo-acoustic foam lay­ers, it is speci cally de­signed for use un­der car­pet with­out the need for un­der­lay.

Dy­nabox and En-Wall

But how about the speak­ers you’re us­ing? If th­ese are po­si­tioned within the wall or ceil­ing with­out a suit­able en­clo­sure, they will send al­most half of their en­ergy out­put back­wards, and un­wanted vi­bra­tions will run ev­ery­where, with noise leak­age into ad­ja­cent rooms.

Hav­ing your speak­ers prop­erly boxed will not only x this, it gives your speak­ers a rigid en­clo­sure from which to re, de­liv­er­ing bet­ter per­for­mance. Ask­ing for the best from an un­boxed speaker is like nail­ing the driv­ers from your nest hi- loudspeakers to a fence pal­ing and hop­ing they’ll per­form to their best!

So the sec­ond two se­crets are Dy­nabox and En-Wall. The Dy­nabox is a ver­sa­tile box en­clo­sure, while the En-Wall uses the en­closed cav­ity of two fac­ing walls to cre­ate the en­clo­sure in which var­i­ous other acoustic com­po­nents sur­round the speaker.

The in-ceil­ing Dy­nabox not only boxes your speaker, it can be tted ret­ro­spec­tively, be­ing made of a black ex­i­ble vinyl which can be ‘scrunched up’ to t through an ex­ist­ing hole and around an al­ready in­stalled speaker. It pro­vides an acoustic en­clo­sure, while also min­imis­ing both ra­di­ated noise trans­mis­sion in un­wanted di­rec­tions, and pro­tect­ing your speak­ers against dust mois­ture and ver­min.

Au­dioX­tra is bring­ing the Dy­na­mat range of so­lu­tions to the Aus­tralian Hi-Fi & AV Show in Syd­ney, so take the chance to ask nd out the silent treat­ment can im­prove your au­dio per­for­mance — even in ex­ist­ing in­stal­la­tions.
