Isolator - 1925 Invented by science fiction pioneer Hugi Gernsbeck, the
“Isolator” was designed to help focus the mind when reading or writing,
by rendering the wearer deaf, piping them full of oxygen, not only by
eliminating all outside noise, but also by allowing just one line of
text to be seen at a time through a horizontal slit.
i think it would do the opposite in my opinion.. i like to have some background noise while reading.. like music or something lol.. plus can you imagine how distracting that must be on your neck? that looks heavy! and scary.. and kind of like a giant dildo... lol.. sorry couldnt resist!!! :))
