Digital bra makes sounds for feedback

Does a digital bra sound weird? And does a digital bra making noises sound weirder? I wonder just where Sarah Layne got the idea for a Digital Bra. I mean besides being a barrel (or rather cup) of laughs, what is its purpose? Apparently the sounds are for feedback, but what sort of feedback exactly. Anyway these noises can only be heard by the touch of piezo discs which are microphones and need to be on your fingers. The digital bra has 2 amplifiers, 6 speakers, 2 piezo disks, netting, cloth material, plastic, cardboard and Velcro. Sarah Layne plans to upgrade the bra. I wonder if this time she wants it to say actual words rather than just electronic sounds. Also, she intends on more digital underwear.
