Abstract
A fire sound simulator includes a random sequencer which produces random signals. The sequencer is connected to a sound synthesizer which transforms the sequencer's signals into random sounds. The synthesizer is in turn connected to a speaker which receives the sounds from the synthesizer for outputting the sounds. The simulator alternatively includes a recording stored on a ROM chip. The simulator may be activated by a light sensitive switch.
