The Underwater Acoustics Laboratory (SAL) was established as a work package of the "National Sonar Naval Units Production and Integration" project initiated within the scope of the MİLGEM project, with the aim of indigenizing critical technologies in the field of underwater acoustics. The Underwater Acoustics Laboratory was accredited by the Turkish Accreditation Agency (TÜRKAK) on September 23, 2014 and announced by BIPM (International Bureau of Weights and Measures) as the Designated Institute responsible for National Standards in the field of Underwater Acoustics in July 2012. Furthermore, in June 2013, TUBITAK became an associate member of EURAMET (European Association of National Metrology Institutes) with the decision of the Scientific Council.

The Underwater Acoustics Laboratory has a 15m x 10m x 7.5m acoustically insulated test pool as the basic infrastructure. In addition, there is a 100 kg and 3000 kg capacity Precision Positioning System basic infrastructure for positioning various sensors and sensor arrays in the test pool. The Hydrophone Test and Calibration System (HTKS) is used for Transmission Voltage Response and Free Field Voltage Sensitivity measurements of transducers in the frequency range of 2 kHz - 120 kHz. There is also a technical infrastructure to perform tests such as Sound Pressure Level (SPL), Directionality Patterns (DI), Linearity, Harmonic Distortion, Hydrostatic Pressure Test, Insulation Resistance Measurements, Impedance Measurements, Mechanical Resonance Frequency Measurements, Mechanical Q Factor Measurements.

The Underwater Acoustics Laboratory has calibration infrastructures for the calibration of electro-acoustic transducers used in the field of underwater acoustics from DC to 500 kHz. In addition, there is a device infrastructure for continuous or instantaneous measurement of human-induced underwater noise and background noise in our seas, and it performs measurement and reporting activities in a wide frequency band (from 6.3 Hz), especially in the frequency band of 1 kHz and below, where marine life is most affected.
