Science: For Eavesdroppers

The Aurex Corp. of Chicago last week announced a new gadget for increasing the hearing range of people with normal hearing. It might also do for eavesdroppers what binoculars have done for Peeping Toms. The “Opeara Glass” was invented by Aurex’ Walter H. Huth. The little whisper-catcher is an inconspicuous cylinder which can be concealed in a pocket and raised to the ear at interesting moments. Inside is a complete battery-powered amplifying system capable of boosting a lovers’-lane murmur into clear-voiced dialogue. Inventor Huth primly suggests that his little tattler will be useful for, among other things, 1) listening to sermons, and 2) helping foxhunters catch the bay of distant hounds.
