Wind Sound Generator circuit diagram:
Using this simple circuit, one can generate the sound of wind. The
circuit is basically an astable multivibrator build around two NPN
transistors.
By adjusting the 1M potentiometer (VR1), the sound can be changed from
that of wind to storm, sound of sea, hiss of escaping gas from a
container through a small hole etc. A 9-Volt or 6-volt unregulated power
supply is enough. How-ever, a battery may be used instead. The output
sound will be slightly changed. The prototype has been successful tested
with the given power supply. Also and 8-ohm, 5cm, low wattage speaker
is recommended.
