To be able to carry out error-free and reproducible measurements, it is recommended that you have your HEAD acoustics measurement systems calibrated once per year. To live up to your quality standards and those of your customers, you should use our service and have calibrations performed either in Herzogenrath or, upon request, at your location. Our subsidiaries in China, Japan and the USA have their own service departments. You are welcome to contact our colleagues in your area directly.
