Guidelines and Applications

Blachford noise control and sound quality materials can be used in a broad range of applications such as heavy trucks, buses, utility vehicles and off-highway equipment. All materials are custom engineered to ensure the best performance at the lowest possible weight and cost. Performance validation is conducted by the Blachford Acoustics Laboratory.

Please refer to the following charts and case studies for additional information.
