Browse Forums General Discussion 1 Feb 01, 2023 4:06 pm I'm considering a new build and want excellent acoustic insulation throughout the house.
Unfortunately excellent soundproofing (for air transmitted sound, not sound transmitted through solid structures) means no air gaps. How does one get excellent soundproofing in a bedroom, for example, and yet still have enough fresh air to breath? There will be no ducted air conditioning - only a split system aircon in the bedroom. Any links to "soundproof" air vents that can be purchased in Australia would be appreciated. Hopefully we have an acoustic engineer as a reader of this thread who is willing to provide some guidance. Re: Soundproofing rooms and air circulation 2Feb 01, 2023 4:18 pm Not sure what you mean under fresh air. You open the window to ventilate and get your air in. Alternatively, you install mechanical ventilation system. No matter how you soundproof the walls, the windows and doors will still be the weakest link. Re: Soundproofing rooms and air circulation 3Feb 01, 2023 4:24 pm Fresh air just means new air coming into the room to replace old stale air. I'd prefer not to have a mechanical ventilation system. (I wouldn't want my guests to suffocate in a bedroom overnight my shutting out the noise and then not getting enough nice air to beathe.) Re: Soundproofing rooms and air circulation 4Feb 01, 2023 4:28 pm Well, there is really no other way around to get the air in - either to open the windows, or to install ventilation. You can also consider something decentralised like Lanos: Decentralised Energy Recovery Ventilation - LAROS https://www.laros.com.au/products-services/energy-recovery-ventilation/decentralised-ventilation/https://www.laros.com.au › products-services › decentra... https://www.laros.com.au/products-services/energy-recovery-ventilation/decentralised-ventilation/ Re: Soundproofing rooms and air circulation 5Feb 01, 2023 4:32 pm you might want to define "excellent acoustic insulation" a bit better, by providing examples of noise sources you are trying to insulate from. there are different solutions available depending on what it is, with some of them not necessarily being within your house. an example would be the sound deflecting fences they put next to the highways where there are houses there. Re: Soundproofing rooms and air circulation 6Feb 01, 2023 4:49 pm Okay, excellent acoustic insulation means the bedroom occupant cannot hear the following noise: - high pitched sirens (police, etc) 100m away - low frequency rhythmic thumping base "music" from suburban neighbours - gunshots or explosions from neighbours - screaming, yelling domestic disputes from neighbours - constant barking from suburban neighbour dogs Re: Soundproofing rooms and air circulation 7Feb 01, 2023 5:00 pm gommeqld Okay, excellent acoustic insulation means the bedroom occupant cannot hear the following noise: - high pitched sirens (police, etc) 100m away - low frequency rhythmic thumping base "music" from suburban neighbours - gunshots or explosions from neighbours - screaming, yelling domestic disputes from neighbours - constant barking from suburban neighbour dogs for low frequency noise, have a look at this page: https://quietliving.co.uk/block-low-frequency-noise/ for gunshots or explosions - install tall deflecting fences around your block, or move to a different neighborhood. everything else - double or triple glazed windows, pack insulation into external and internal walls and ceiling, seal the gaps, use acoustic gyprock panels, glue etc. for ventilation - keep in mind that the sound is not carried by air. it's a wave that travels within the channels, bouncing off the walls. so if you design the channels in such a way that the sound waves bounce back and cancel each other out, they will not transmit the noise. If you don't want to annoy the neighbours then simply get yourself some good head phones. For me the sound is much better using headphones.
