These sound active EL T-shirts have strong sensibility to the sound. When there is any sound, such as music, or even the sound comes from people talking, the panel on the T-shirt will flash to the beat of the sound. Its sensibility to the sound can be adjustable by turning the knob on the sound inverter.
