I have to admit I hadn't thought about this, but an audio-based alarm is of no use to a deaf homeowner. There may be some that flash lights, as is done to replace ringing phones. But this alarm will awaken a sleeping deaf person - it sprays wasabi into the air. It's still in the development stage, but the inventors claim "...Prototypes of a new silent smoke alarm that sprayed canned wasabi extract into a room succeeded in waking 13 out of 14 test subjects within 2 minutes. One subject who is actually deaf awoke a mere 10 seconds after the wasabi essence was sprayed..." Credit to Neatorama.

A smoke alarm for deaf people
