So my dad is deaf in one ear will subs work?

My dad is deaf in one ear will subs still be effective for him?

[Guero]

I asked about using one ear bud before and Shannon said it'd be about 45% effective

Yes, it can work, but the final effectiveness will depend on how it's used, the type and degree of deafness and which format he uses.

Ultrasonic is best for persons with deafness issues because it is both the highest in volume for the actual subliminal audio, and because ultrasonic audio can bypass some types and degrees of deafness.

Regardless, it should still work with one ear, but any stereo effect will be lost, which will make it somewhat less effective. But it will still work.
