This wind sound effect generator circuit perfectly imitate the noise of the wind. Transistor T1 is connected as a Zener diode and will provide a noise signal to T2. The amplified signal by T2 is led ...

Many species of owl are able to hunt in effective silence by suppressing their noise at sound frequencies above 1.6 kilohertz (kHz) - over the range that can be heard by humans. A team of researchers ...

Discover the main disadvantages and engineering challenges associated with wind generators in this detailed video. We start ...
