Four high-intensity LED's light up and react simultaneously to every sound. For different funny and practical applications e.g. sound indicator, simple sound-to-light unit for music. The unit can also be used to indicate when the doorbell or the telephone is ringing, which is particularly interesting for the hearing-impaired. Adjustable sensitivity with potentiometer. Built-in microphone.
