It's almost sound proof inside a car : apply similar idea to sound proof a room?
Posted on 2015-01-01
I noticed that even if my autist son shouts at his loudest while inside the car (with the car windows
closed), we can't hear him.
As he makes a lot of noise inside his bedroom or when he's in the living room, it affects/disturbs
his NT sister who is in another bedroom & are often 'super-annoyed' by his wailings/noises
In another EE thread, someone has suggested using styrofoam with bubble wraps but I wud say
this cuts out only about 50% of the noise.
What makes the car soundproof? Thought of applying the same on the bedroom's doors as I'm
certain the noises travel thru the wooden doors (not via the thick walls & glass windows) : I can
even feel the vibrations of the noises when I put my ears on the wooden doors.
I can certainly engage professional anti-acoustic contractors to soundproof but I want to DIY
currently as I may not stay long at this house.
I did buy ear plugs for my girl but she doesn't feel comfortable wearing it most of the times
