About

Cambridge Acoustic Laboratory Limited (CALL) is a purpose built sound transmission suite offering laboratory sound insulation testing in accordance with the BS EN ISO 10140 series of standards.

Through the use of an innovative design of modular steel panels forming spaces in the partition wall, a wide range of products of varying sizes can be tested without the need for resorting to more traditional time-consuming and messy wet trades.

Our facility features cutting-edge measurement equipment and is run by staff with years of sound insulation testing experience.

Recently established alongside parent company Cambridge Fire Research, our Pampisford site is able to offer the convenience of sound insulation performance testing and fire performance testing in one place.
