Can young teens use ASC?

Jones, please watch the volume levels with your son too!

Funny you should say that!

I've been casting about for a way to play subs for him in the background. Ultrasonic will simply not do, it bothers his ears (kids have much more sensitive hearing that us old folks).

I'm going to have to EITHER experiment with the volume of the ultrasonic on the mp3 player/Oontz angle 3 speaker combo I got him... OR stick with the babbling brook (his preference) in the background on a shelf.

I understand that's not ideal, but a kid needs to be busy playing during the summer, not being conscientious about keeping the ear buds in.
