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.
When I said that Googleâs plan was audacious, I said so because of the cost. For starters, Google wants to offer 1 gigabit-per-second speeds to some 50,000 to 500,000 people. At 2.6 people per household, that roughly translates to between 20,000 and 200,000 homes.
