Hi Hannah...
About your question..
This Sound Shirt can pick up different sound.
one of it is  deeper,heavier bass notes.
* bass : The lowest part of the musical range, lowest voice
When the Sound Shirt pick up this kind of sound, it will activate the circuit in the shirt located in the lower part of the torso.
