In telecommunications, the term channel noise level has the following meanings: 1. * The ratio of the noise in the communication channel at any point in a transmission system to an arbitrary level chosen as a reference. 2. * The noise power spectral density in the frequency range of interest. 3. * The average noise power in the frequency range of interest. (Wikipedia).
In this video i demonstrate sound waves interference and standing waves from loudspeaker used sound sensor. The frequency on loudspeaker is about 5500Hz. Enjoy!!!

Show Me Some Science! Speed Of Sound
Sound is a wave which travels through the air at about 330 m/s. The Little Shop of Physics Crew dances to the music together. When spread out along the track, it takes about a third of a second for the sound to travel from the first person to the last. The crew is blindfolded, so there are
