Ping360 – Worst-case acoustic output or power density estimate

Hello everyone!

We are integrating a Ping360 scanning sonar into our system and are performing a system-level energy and safety evaluation.

We have reviewed the publicly available documentation and Ping Viewer materials, but we could not find explicit information regarding the acoustic output expressed as sound pressure or power density.

For engineering purposes, we are specifically interested in establishing a conservative upper bound. With that in mind, we would like to ask if is possible to estimate a worst-case acoustic output or power density (e.g. W/cm² or W/m²) for the Ping360, assuming the most aggressive configuration available in software (maximum transmit duration, shortest range, highest ping rate, etc.)?

We are not looking for exact or guaranteed values, only a reasonable worst-case estimate or guidance that can be used for conservative engineering analysis.

Any insight, references, or experience would be greatly appreciated.

Thank you!

Hi @olsfraga
Welcome to the forums!
Unfortunately, we don’t have a value for sound power levels associated with the Ping360 - see this thread.

Since the unit uses about 5 watts, and at least 1-2 watts of that are used by the electronics / converted to heat, that leaves a few watts at most of sound power entering the water. I’ve never been able to hear the unit underwater, even with my ear up against it, due to the high frequency being well outside the range of human hearing…

In short, not a safety concern as far as I can imagine!

Thanks for the quick reply!
That answers our question well, I think this is enough for us to move forward with the Ping360.
