Sound Waves and Beats. Sound waves consist of a series of air pressure variations. A Microphone diaphragm records these variations by moving in response to the pressure changes. The diaphragm motion is then converted to an electrical signal.Using a Microphone and a computer interface, you can explore the properties of common sounds.ound waves consist of a series of air pressure variations.

Google Fiber Speed: By the numbers. The average Internet speed in the U.S. is 7.4 megabits per second (Mbps), according to a âState of the Internet Reportâ released by Akamai Technologies. It seems that the U.S. has some catching up to do in this department.
The projected capacity of a single fiber communication channel of 10 12 bits per second (1 Terabit/s), which the figure above suggests will happen around 2,005, is already here. Worldwide Internet traffic is about 1 Terabit per second, and could therefore, in principle, be carried on a single optical fiber.
