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.

Hi Shannon,
I have downloaded the experimental pack and chosen one to experiment with. It is ultrasonic and there is no other option of choosing a masked one so I have to use ultrasonic only and that too using earbuds.

I have taken every precaution to calibrate the volume using the previously downloaded ASC 4G masked file for using this experimental ultrasonic. Using day and night what should be the optimum total time to play this sub?

One more important question regarding the ultrasonic subs, teenagers are able to detect these ultrasonic, can it be considered as an evidence to know whether the speakers/earbuds/headphones are compatible to play these files? beside the audio test file.

You don't need any evidence besides the speaker test. But if you have a teenager who can hear them, without any static, obviously they're playing.

I suggest getting as much exposure every day as you can.
