Calibration in acoustics

Extended service portfolio for acoustic measuring equipment

In addition to important upgrades in the accredited calibration laboratory for acoustic measuring equipment, SPEKTRA received a new certification in October 2022: as a recognized certification laboratory - to take over the initial calibration of sound level meters and sound calibrators. This brings a new added value for our customers with sound level meters, calibrators and measuring microphones.

Listening to our customers

The latest extension in our acoustics laboratory resulted from an exchange with one of our customers in the railroad industry. In addition to the usual calibration, this customer also required the verification of sound level meters for the excess level as well as the maximum cycle level according to DIN 45657:2014 at DAkkS level.

Since October, SPEKTRA has been one of only three calibration laboratories that can offer this service in its well-known high quality and reliability.

DAkkS certificates can now also be issued for the calibration of the sound pressure level of measurement microphones, sound level calibrators and sound level meters at the reference point 250 Hz / 94 dB and 114 dB. These and all other accredited measurement quantities can be found in our current certificate.
