PACS is an easy-to-use system allowing the user to perform a variety of tests for sound source calibration. Due to its portability, PACS can be used from vessels of opportunity in various size bodies of water, or in-house test tank setups.

  • Transmitting Voltage Response (TVR) of sound sources
  • Transmitting Current Response (TIR) of sound sources
  • Receive sensitivity of hydrophones
  • Source level measurements
  • Complex impedance/admittance curves
