I can just barely hear it with my laptop speakers turned all the way up and only in my left ear. Even then, its some annoying sh!t. I've heard about malls and shopping plazas using them to thwart teenage loiterers and always wondered what it sounded like.
I actually thought it was some fake sh1t ,till my son came in the room, i played it ,
He made a really weird face and started ow! ow! turn that off ,what are you doin,ah! ah!
