Problem: I’m being driven mad by voices speaking to me thru white noise. Need white noise to sleep

Psychiatrist today suggested:

1. normal human speech has typical rhythm, cadence
2. fans, white noise audio files are always looped, rhythms in it
3. brain is hearing those patterns as human voices
4. I need to introduce staggered rhythms to disrupt

Possibilities:

1. Willie Nelson, William Shatner speak with atypical cadence. Play at same time as white noise
2. phone app that vibrates atypically
3. machine in room that generates atypical rhythms, vibrations

Options, ideas? I’d like not to go further insane
