Tailored solutions for every testing need
Custom-made measurement cells and acoustic test facilities
Every application has its own acoustic and functional requirements. Merford designs and builds test rooms based on the client’s specifications, ranging from compact test spaces and audiometric cabins to advanced test laboratories and (semi-)anechoic chambers.
Our solutions achieve sound insulation values (Rw) of up to 50 dB and absorption coefficients of up to 1.0.
Solution highlights
Engineered for interference-free sound measurements
Composition
Each test room is built from self-supporting, modular panels with high sound insulation. The panels are available in corrosion-resistant steel, aluminium or stainless steel for added durability.
Custom options
Choose from various RAL colours, surface coatings and acoustic fillings to match performance and appearance. Each room can include doors, windows, silencers, dampers, fans and floating floors.
Modular and adaptable design
The modular construction offers full flexibility in materials, dimensions and layout. Cut-outs and component integration can be fully customised to meet the requirements of your project.
Proven acoustic performance
Every solution is engineered and tested according to strict acoustic standards, ensuring reliable noise reduction and compliance with industry norms.

Monday to Friday — between 09:00 and 17:00
Can doors, windows, and ventilation systems be integrated without compromising performance?
Yes. All components, including doors, windows, fans and dampers, are designed to minimise sound transmission while maintaining optimal performance.
What is the lead time for the realisation of a measurement cell?
The lead time depends heavily on the complexity and specifications of the project and whether it involves a new measurement cell or the modification of an existing one.
Does Merford upgrade or renovate existing measurement cells?
Merford both constructs new and upgrades existing measurement cells.
