#soundinsulation #db #autoinsulation
Hello all and welcome to my channel.
In this video, I will share with you how I made sound insulation between the engine compartment and the driver's cabin of my vehicle.
I took sound level measurements before and after insulating. However, as I mentioned in the informational text at the beginning of the video, unfortunately, I could not find the measurement photos and videos of this insulation application I made 5 years ago. That's why I won't be able to share these images in this video. If I remember correctly, I detected a 3-4 db reduction in sound level. This value is successful because the noise level measurement increases and decreases logarithmically.
I cleaned the area I was going to coat and wiped it with isopropyl alcohol. To ensure the adhesion of the butyl rubber at the bottom of the insulation material, I created small scratches by pressing the socket wrench extension arm from the top of the insulation material.
While applying, I made sure that the surface and air temperature were above degrees Celsius in order to ensure good adhesion of the insulation material. I did the application in the summer.
You can find other explanations in the video.
Enjoy watching.
