Abstract
A new Fire Sound Simulator for simulating the hissing, popping and crackling sound of a fire includes a white noise generator for generating a white noise signal representative of a hissing sound, a ROM-based sound generator for generating a popping signal representative of a popping sound, a ROM-based sound generator for generating a crackling signal representative of a crackling sound, a microcontroller operably coupled to the ROM-based sound generator for generating the popping signal and the ROM-based sound generator for generating the crackling signal, the microcontroller generating a first start signal for activating the ROM-based sound generator for generating the popping signal and a second start signal for activating the ROM-based sound generator for generating the crackling signal, a mixer for mixing the white noise signal, the popping signal and the crackling signal, and for generating an amplifier input signal, the mixer being operably coupled to the microcontroller, an audio amplifier for amplifying the amplifier input signal and for generating an amplifier output signal and a sound speaker connected to receive the amplifier output signal.
