Abstract
There is disclosed an alarm clock in which the alarm sound is changed automatically at periodic intervals. In the illustrative embodiment of the invention, the clock emits eight different alarm sounds, and the alarm sound is changed automatically every 24 hours. By so changing the alarm sound, a sleeper cannot become accustomed to one particular alarm signal, thereby becoming "immune" to it.
