The Hydroacoustics Testing Laboratory specializes in testing underwater acoustics devices and systems, in particular:

  • hydroacoustic transducers,
  • passive and active sonar systems,
  • underwater telemetry systems,
  • underwater monitoring systems for harbors, shipyards, river dams and other hydrotechnical structures,
  • underwater communication systems.

Tests of hydroacoustic transducers consisting of measuring:
 - pressure response to voltage excitation (Transmitting Voltage Response - TVR)
 - voltage response to acoustic stimulation (Pressure Sensitivity - PS)
are made in accordance with the PN-EN ISO/IEC 17025:2018-02 standard. The laboratory performs the above tests according to its own research procedures developed based on the PN-EN IEC 60565-1:2021-02 standard. Detailed measurement ranges are specified in the table below.

The Laboratory is equipped with specialized equipment enabling it to conduct statutory activities and conduct scientific research. The laboratory conducts research both in its own anechoic measurement pool and in the open inland waters on Wdzydze Lake, as well as directly on vessels moored in port basins or during sea trials.

Institutions or individuals (including graduates of metrology-related fields) interested in cooperation in conducting scientific research are welcome to contact the Laboratory Manager.

The laboratory also offers training for institutions and individuals on the above-mentioned topics.

The price and scope of services provided are determined individually.
