In February 2014 SPEKTRA has been successfully accredited to calibrate artificial mastoids. Those mastoids are usually used in the field of audiometry. Consequently, SPEKTRA is the first calibration laboratory to recieve this accreditation in Germany and can now offer this sort of calibration.
New sensor technologies based on micro-mechanical structures (MEMS) increasingly require mechanical tests in the frequency range beyond 20 kHz. In this high frequency range, the trick is to stimulate the DUT with well-defined oscillations without causing uncontrolled vibration and transverse movements by resonance of the exciter. The new SE-11 vibration exciter provides the ability to excite the DUT with very low lateral accelerations to the main axis of motion in the frequency range of 1 kHz - 50 kHz.
The SPEKTRA Schwingungstechnik und Akustik GmbH Dresden was founded in 1994 and has since developed into one of the leading suppliers of calibration, measurement and test systems and services in the fields of vibration and acoustics.
