Acoustic Vinyl Soundproof Layer. The acoustic vinyl layer reduces sound transmission by 60 more than traditional windshields. Add mass loaded vinyl mass loaded vinyl mlv is a soundproofing material that comes in thin rolled sheets. Mlv soundproofing offers an alternative to lead at a lower price point.
Most of the noise reduction is in the mid to upper noise range especially in the 1 500 to 5 000 hz range of frequency. Acoustic vinyl windshields meet all of the same federal safety specs as regular vinyl windshields.
It reduces overall noise transmission by 2 to 3 db but some frequencies by over 6.
Use this acoustic underlayment for carpet and other floor materials. Mass loaded vinyl is typically hung inside a wall cavity as an extra barrier against sound. The increased density provided by mlv also increases middle and high frequency sound control. Designed for floors and walls and vehicles.
