Beasely's Phonetic Harmonizer
"Developed by Dr. Hugo Beasely in 1906, the Phonetic Harmonizer amplifies ambient background sounds, allowing the wearer to overhear conversations over greater distances than is normal for the human ear. The apparently clumsy looking device is actually a miracle of micro electronic circuits, chemically treated sound amplification baffles, and gyro stabilization. Consisting of a large black box attached to either the right or left sides of the head, centered on the ear, and secured with several straps, the Beasely Phonetic Harmonizer is then modified by the wearer for current operating conditions. Attached to the opposite side of the head from the Harmonizer is a smaller box containing a ether gyro resting in artificial inner ear fluids and light weight lubricants. The harmonizer itself has an attached external sound collector resembling an old gramophone horn (built under license by HMV in the UK and RCA/Victor in the US), which transmits sound into the harmonizer itself. Inside the harmonizer, sounds are reflected off chemically treated baffles amplifying the sound to levels understandable to the wearer. If the sound is still too indistinct, more baffles are inserted or a larger external sound collector is attached. The ear has a range of approximately one kilometer on clear days, about half that in rainy or snowy weather. Special baffle inserts to filter out weather noises or the sound of the wind are available directly from the manufacturer for a small additional fee".
