HOW TO GIVE YOUR AUDIO SYSTEM THE SILENT TREATMENT
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.
