Anyway, you recommend listening to these subs over headphones. I do remember before that you don't recommend listening to ultrasonic subs using headphones as they might damage your hearing. Is this not applicable anymore?

Reposting this because Shannon might have missed my question here.

It is more effective and efficient to use them with headphones, because that gives you the full stereophonic experience, which has a big impact on the effectiveness and speed of the programs. But using headphones or earbuds with ultrasonics has two distinct drawbacks.

First, if you turn the audio down too far (or to zero), you won't necessarily know it. I've had testers tell me frustratedly that weeks have sometimes been wasted because they disconnected a cord or turned the volume too low and didn't realize it.

And secondly, ultrasonic audio is audio, just as normal audio. Too high a volume and it can have the same effects as high volume audio in other formats. This becomes a problem because a lot of people tend to want to play it too loudly because they can't hear it and they want to make sure it's actually working.

I recommend using headphones for maximum effectiveness, and not using ultrasonics if you do use headphones. If you choose to use ultrasonics with headphones regardless, you must be extremely vigilant about volume and safety. Since most people are not going to be able to do that - I advise against doing it at all. Use a masked track with headphones.
