Diminutive “Super-Ear” for Deaf (Jul, 1930)

Diminutive “Super-Ear” for Deaf

A HIGHLY sensitive detector of sound known as the “Super-ear,” a device which operates on a new and unique principle, has recently been put on the market for the relief of deafness. The “Super-ear,” one method of the use of which is shown in the photo at the left, is adaptable for use in any position. It can even be concealed in the palm of the hand, and attracts little attention. It operates by compressing the received vibrations of sound into a series of successively smaller chambers, thus securing greater intensity.

    It’s just a matter of time before someone puts this on and tells us the advantages of either Shamwow or the Slap Chop

    That block of metal Uhura had jammed in her ear in “Star Trek” was smaller than that. Of course we have smaller hearing devices now than that thing Uhura used.
