Without laminated glass or an acoustic grade glass there won t be a huge acoustic difference.
Acrylic sheet noise reduction.
1 4 laminated glass is much better at killing sound than 1 4 acrylic higher density plus it has a layer of pvb plastic in the middle that helps break the vibration.
This material is sound insulating impact resistant and highly transparent.
Plexiglass noise reduction sound barrier plexiglas sheet offers sound loss characteristics that are equal to or better than those of glass.
Using two sheets of window grade plexiglass leaves a void in the middle which gives you dead air.
This method is pretty effective when it comes to diy ways of soundproofing windows.
All sheets can be provided with various functional surfaces for specific applications such as bird protection and embedded polyamide filaments for fragment retention used with structure mounted noise barriers.
As always thicker is better so use two sheets of plexiglass around inch thick.
In order to reduce the noise levels coming from the outside we can attach a piece of acrylic or glass over the inside of the window.
Thankfully i have brick exterior so hoping window is main source of noise.
A 2 inch 50mm airspace between glass panes will provide better noise reduction.
What may be considered as music to one person may be noise to another.
But be careful though.
Acoustical windows are made from two panes of thick specialty glass.
Oddly enough the manual doesn t talk about acrylic windows something that should have been widely available in 1985.
Good sound insulation n oise reduction mechanism of acoustic panel is reflected rather than absorbed.
Noise is undesirable and unwanted sound.
But as you ve said it s not availiable so go with acrylic but go thicker 3 8 to 1 2 as much as you can afford.
The thicker the mass of the soundproofing barrier the greater the noise reduction it provides.
Has anyone compared the acrylic sheet to soundproof windows.
Since plexiglas sheet is also more resistant to breakage it can be used as a transparent sound barrier to reduce noise levels and increase safety at the same time.
Not all sound is noise.
I have heavy road noise and large window opening 63 x70.
Build your window with two panels of plexiglass that are at least 3 8 to 1 2 inch in thickness.
After testing 15 and 20 mm acrylic sheet respectively 32 and 35 db noise reduction if the top of the acoustic panel made inwardly curved shape sound effects will be better.
Noise pollution noise may not seem as harmful as the contamination of air or water but it is a pollution problem that affects human health and can contribute to a general deterioration of environmental quality.
Tables 1 2 and 3 show noise reduction values and stc ratings for plexiglas sheet.
Providing you seal the edges properly plexiglass will do a good job of eliminating outside noise.
