Universal Sound Signaler No more missed phone calls. No more missed kitchen timers. No more missed knocks at your front door. With its endless number of possible uses and its ability to be used anywhere there is an outlet, the Universal Sound Signaler is a valuable visual tool for the hearing impaired. Designed to pick up even the faintest sound, the Universal Sound Signaler can be placed next to almost anything that emits sound: an alarm clock, a kitchen timer, a telephone, or anything else you can think of. Simply plug the cord into any standard outlet and place the Universal Sound Signaler close to the sound it will be monitoring. Then plug any lamp into the outlet on the back of the plug and it will flash when triggered by the sound. You can adjust the sensitivity of the Universal Sound Signaler by turning the knob on it and the lamp can still be used for regular lighting by using the integrated on/off switch.
