Smoke Alarm For Deaf People


Next to not being able to listen to music, one can imagine that one of the worst aspects of being deaf is the inability to hear warning signs. Thankfully, Air Water Safety Service, a fire extinguisher company based out of Kobe, Japan, and Seems, a bioventure in Tokyo, have developed a device that warns the deaf of impending fire that isn't dependent on a shrill noise.

The alarm device emits the pungent aroma of allyl isothiocyanate, the chemical compound responsible for giving foods such as wasabi and mustard that pleasant kick guaranteed to clear the sinuses.

The device spreads a smell that WILL wake you up. It was tested on subjects that were completely deaf, as well as those with normal hearing.

In each case, every subject, regardless of hearing, woke up within approximately two and a half minutes.
