I am working on acoustic characterization of microbubbles using two transducers arranged at 90 degrees. During calibration, I am receiving response in dBm or mV. How I can know the PNP of my acoustic pulse through it??
Dear,
You need to go through the datasheet of transducers being used. Generally there should be relation between input and electrical output. Also, you need to consider the dynamic behaviour of the transducer. If you share the details of transducer probably it would be easy to comment.
P. K. Dubey Its Technisonic ISL-0302GP transducer. at 3.5MHz frequency. Attached is catalo, which didn't provide any other information except for frequency and element size
Dr Riaz ---Have a look at the following useful link:
https://www.translatorscafe.com/unit-converter/EN/microphone-sensitivity/6-1/
and voltage to pressure conversion , please see:

Ijaz Durrani Thanks but for all that, I need needle hydrophone as it can only give sensitivity in V/kPas.
Is there any way to calibrate transducer without needle hydrophone?
And are they available in Pakistan? As import takes time and I need it urgent.
