Acoustic Testing
Marport C-Tech offers comprehensive acoustic testing services at its underwater acoustic test facility (UWTF).
The Company's underwater acoustic test facility is located in an area remote from environmental noise, providing an acoustically quiet and stable environment. The site measures 140 metres long, 100 metres wide and 13.5 metres deep.
On site, Marport C-Tech has a fully instrumented floating, moored barge. This facility allows us to measure, record and calibrate sensitivity characteristics of projector and hydrophone arrays at frequencies from 50 Hz to 200 kHz.
The barge can accommodate transducer array sizes ranging up to 5000 kg in weight and operates year round.
Acoustic Tests
- Beam Patterns (horizontal and vertical)
- Polar and rectilinear directivity patterns
- Source level test (transmit)
- Recieve Sensitivity
- Hydrophone calibration
- Deep submergence acoustic testing, .05-10 kHz at 0-500 psig
Underwater Acoustic Test Tank, UWTT
The UWTT is a cylindrical redwood tank 6.4m in diameter and 3.6m deep. It is located at Marport C-Tech's main facility and is used for near-field acoustic transducer measurements ranging from 3 kHz - 200 kHz. Typical acoustic tests performed using the UWTT are:
- X-Y Admittance Plots
- X-Y Impedance Plots
- Resonance
- Source Level
Hydrostatic Pressure Testing
A pressure vessel provides automated programmable pressure cycle sequencing to a maximum pressure of 1210 psig. The vessel chamber measures 24 inches in diameter and 84 inches high.
