Pacemakers?

[BoneOctopus]

Hey!
First off, super cool project. I just wanted to ask if there was any known issues with this product and pacemakers, as ultrasonic sound can mess with specific kinds.

I doubt that any pacemakers would be affected by any kind of ultrasonic noise at < 100 decibels.
I mean we are surrounded by ultrasonic noise every day. I mean just think about all the electronic devices in your house: https://en.wikipedia.org/wiki/Electromagnetically_induced_acoustic_noise
Or what about dog whistles? Do you think a pacemaker would be approved if it would be affected by stuff like that? Seems unlikely to me.
