What ringtone is the loudest?

The loudness is only going to be determined by the volume control.

I mean, does anyone have a suggestion as to what ringtone (or song) is particularly louder than another. Usually, a ringtone in a higher register is easier to hear. Or, a song like James Brown’s “Shout” may be louder than a violin piece. I’ve already got my volume as loud as it will go. Any other ideas?

I made a custom ringtone for by wife – an old Belgian phone ringing – and edited the file in an audio-editing program to boost its volume.

I’ve found the “Old Phone” ringtone can really “cut through” when the ringer volume is turned up all the way.
