Problems solved by technology

The disadvantage of this approach is therefore that good sound insulation pads add significant weight to the vehicle which negatively impacts the performance of the vehicle and the economics of using fuel
Another disadvantage of this approach is that highly sound absorbing materials also typically have low transmission losses

Abstract

The disclosed acoustic insulator mat includes a first absorber layer made of a non-woven fibrous material. The non-woven fibrous material comprises a mesh of intertwined fibers that defines a plurality of cavities. The first absorber layer has a first side and a second side. Peripheral cavities are arranged along the second side of the first absorber layer between peripheral fibers. A coating is disposed on the second side of the first absorber layer. The coating is adhered to the peripheral fibers and thus includes a plurality of discontinuities at the peripheral cavities such that the coating provides a partial barrier to noise at the second side of the first absorber layer. The acoustic insulator mat may optionally include a second absorber layer that is retained on the first absorber layer by the coating. A method of manufacturing the acoustic insulator mat is also disclosed.

Description

[0001] Cross-references to related applications [0002] This application claims priority to US Patent Application No. 15 / 096,332, filed April 12, 2016, and US Provisional Application No. 62 / 147,066, filed April 14, 2015. The entire disclosure of the above application is incorporated herein by reference. technical field [0003] The present disclosure generally relates to soundproofing mats and methods of making the same. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Acoustic insulators of the type described herein are commonly used in automobiles and other vehicles to reduce the amount of noise experienced by passengers. Also known as a noise attenuation system, such sound-insulating pads are usually made of foam and / or "trash" materials that are stacked into a lightweight structure. Trash materials are typically made of a two-component cotton or other noise-absor...
