Acoustic impedance is a measurement of the speed of sound as it travels through a medium. It is very important in the study of acoustics because it can be used to determine the speed of sound as it travels through different objects and materials, such as rocks, walls, air, and water. By changing the experiment’s conditions, a user can measure a sound wave’s acoustic impedance and modify the wave to produce an ideal sound, a technique that is often used in music, construction, and even industrial environments. How Acoustic Impedance Read More

The DirecTV Single Wire Multiswitch (SWM) is a specially designed piece of hardware that allows a DirecTV satellite dish signal to be split and used with many different tuners/receivers.
