We provide expert calibration for 1/1-octave and 1/3-octave filters used in noise analysis. These filters are calibrated to the requirements of IEC 61260, the international standard for electroacoustics that specifies the performance of octave-band and fractional-octave-band filters.

With this service, we verify the accuracy and performance of the filters in your SLM or standalone analyzer, ensuring that your instrument delivers precise frequency analysis for environmental noise, industrial hygiene, or any other application requiring detailed acoustic measurements.
