Ultrasonics. Hydrophones - Measurement and characterization of medical ultrasonic fields up to 40 MHz Ingestion-build-266356 These devices can be used1 Scope and object This part of IEC 62127 specifies methods of use of calibrated hydrophones for the measurement in liquids of acoustic fields generated by ultrasonic medical equipment operating in the frequency range up to 40 MHz. The objectives of this standard are: to define a group of acoustic parameters that can be measured on a physically sound basis; to define a second group of parameters that can be derived under certain assumptions from these
