There will be a spike up to the right, and that is the volume of the ultrasonic (high pitch) that is playing. Once you know what that volume is, turn off the ultrasonic on your smart phone and turn it on on your old phone. Adjust the volume until the spike to the right registers the same volume when you have the microphone of the smart phone exactly as far away from the speaker of the other phone as it is to the speaker on the smart phone.
That will be the correct volume.
Better yet, just play it on your smart phone.
Hey. Just did some tests here. With my smarthphone with 13/15 volume clicks, it can reach -45 db in the app.
And with the cellphone (nokia c3) I can reach -55 at max volume. So using it all max volume would be the ideal?
