Testing Services

We have extensive capability for measuring acoustic properties of materials and the acoustic fields generated by devices. These testing services are available under strict confidentiality.

Our test facilities include our in-house OptiSon® Analyzer, a 3-axis scanning system, calibrated hydrophones, and a full compliment of all necessary electronic equipment.

Hydrophone Calibrations[pdf]
Onda's acoustic measurement lab is well equipped for providing precision hydrophone calibrations over the 20 kHz through 60 MHz range.

Regulatory Measurements
Measurements to verify compliance with FDA or IEC requirements related to ultrasound are performed by members of our senior technical staff. Since accuracy and repeatability are crucial for these measurements we provide a comprehensive test report that includes a description of test methodology, error analysis, calibration procedures, and all acoustic output tables, graphs and images.

Sample Reports

Implantable Devices
Onda also provides exposure testing of implantable medical devices for compliance with section 22.1 of EN 45502-1.
