We perform constancy tests to validate hydrophone sensitivity. This includes adjustment of the test probe and hydrophone, measurement of hydrophone sensitivity using a validated test pulse, and comparison of the resulting signal waveform with the calibration data.

We perform sound field measurements to determine acoustic parameters of sound sensors. This includes quantitative testing of ultrasonic transducers and devices as well as the planning and execution of two- and three-dimensional sound field investigations. Our laboratory is equipped with positioning system, water tank, pulser, frequency generator, power amplifier, and oscilloscope. For precise results, we use a calibrated membrane hydrophone. All measurements are carried out by experienced personnel.

- Acoustic impedance
- Absorption coefficient
(incl. data file and protocol)
We offer testing services for the controlled exposure of active implantable medical devices (AIMD) to diagnostic ultrasound. The procedure is carried out in accordance with DIN EN 45502-1 / IEC 45502-1 (“Active implantable medical devices – General requirements for safety, marking and information”). The scope of services includes the exposure of the implant to diagnostic ultrasound fields, stepwise positioning of the device to ensure complete area coverage, and measurement of the ultrasound source intensity. A final test report is provided, including the procedure, exposure protocol, and measurement data.
Please note: This service covers only the ultrasound exposure of the device; the assessment of device performance after exposure remains the responsibility of the client.
