　　Welcome to 'Inventors' Corner'. This week we take a look at an invention that may well change the way in which you listen to your television set. Four years and twenty thousand pounds later, Susan Schofield of Cardiff, Wales,believes she has the answer to that nagging¹ problem of listening to advertisements at twice the volume of theprogram you are watching. Annoyed at having to reach for the remote control every time an advertisement comeson the screen simply to avoid being deafened², she came up with the idea of a small device that detects when anadvert is being shown, and automatically reduces the volume to a preset level. Why not cut out the soundcompletely? Well, that's possible if you wish, but too often, of course, the viewer misses the first few secondsof the show returning to the screen. Now, the volume is totally at your control.
Just how the device works is a patented secret, but together with her husband, a television repairman by trade,she was able to create an electronic box no bigger than your thumb that attaches to the back of the remote controlitself. The only drawback is the remote must always be pointed³ directly at the TV set. However, Susan doesn'tthink this will detract from its selling power, and Susan ought to know. It was she who invented that other best-selling gadget⁴ we featured on the show two years ago. I refer, of course, to the telephone answering machine thatautomatically answers with a message that changes depending on the voice of the caller. Looks like Susan's doneit again, with what she calls the 'Ad Subtractor'.
