            Test Cells and Measurement Cells

            Optimal sound analysis using Merford’s test and measurement cells

            Test and measurement cells provide an important added value in various applications. There is a distinction between test cells and measurement cells. Test cells are chambers where power output tests are conducted with vehicles such as motorcycles and cars. Here it is important that the associated noise pollution stays within the chamber, so that personnel does not run the risk of incurring hearing damage. Measuring cells are used to conduct measurements that may not be influenced by sound from the external surroundings, such as acoustic transmission and reception rooms and rooms for conducting audiometric (hearing) tests.

            Comprehensive solution for test cells
            Applications of this nature require an elaborate approach. In many cases, the chamber must be equipped with specific test or measuring equipment, a gas exhaust system and ventilation facilities. The test cells are always equipped with (forced) ventilation to remove the heat created within the test cell. The necessary air flow is determined by Merford in conjunction with the customer based on the capacity of the test object. The ventilation has heavy acoustic dampers that have the same insulation values as the panels used. These sound dampers are of a high quality and are cleanable. The acoustic ventilation system can also be used to simulate driving winds at high speeds. Ventilation flows of up to approx. 200,000 m3/hour are possible.

            Measurement cells for pure results
            Our measurement cells can be fitted with a silent ventilation system, optionally in combination with filters and (fire) valves. Merford’s measurement and test cells can be constructed using individual panels. This makes it possible to disassemble the cells fully or in part to be rebuilt in another location. Furthermore, hatches, doors, or roofs and walls that slide fully open can be installed.

            Relevant cases

            • Ghent University
              Effective acoustic research in the hemi-anechoic chamber of Ghent University

              During the first months of 2016 Merford Noise Control realized a hemi-anechoic room for Ghent University, Belgium. Chambers like these get used for acoustic research where reverberations must be avoided. The room for Ghent University features a cut-off frequency of 63 Hz. Merford took care of the full solution, from engineering to installation.

            • Emerson
              Acoustic test cell adjacent to noisy Emerson production facility

              A subsidiary of Emerson Climate Technologies is located at the foot of the High Fens in the municipality of Welkenraedt in Belgium. Emerson asked Merford to create an acoustic test cell that would enable the company to measure the acoustic power of its compressors in spite of the noise produced by the production hall. The acoustic test cell supplied by Merford consists of two superimposed SKS enclosures and meets this requirement.

            • Anglo Belgian Corporation
              Large Test Cells for ABC Engines

              Merford has supplied the largest test cells it has ever built in the Benelux countries for the huge diesel engines manufactured by ABC (Anglo Belgian Corporation) in the Belgian city of Ghent. The test cells consist mostly of concrete, and have removable acoustic wall and roof components. The concrete walls have SKA absorption panels. The test cells also have a ventilation system with silencers and rain hoods. A third test cell will be delivered at the end of 2014.
