What is Sound? - Quickly Discover What Sound Really Is
What is Sound? This simple demonstration visually shows how sound waves are produced from a vibrating surface. A frequency generator is hooked up to a power amplifier, and the resultant signal is used to drive a loudspeaker. The signal is also sent to an oscilloscope. After listen

How electrostatic speakers work
Here's how electrostatic speakers work. Unless your an audiophile, you've probably never heard of the electrostatic loudspeaker. Electrostatic loudspeakers are pretty hip in the audiophile World because they exhibit levels of distortion one to two orders of magnitude lower than conventi
