Summasound waves!

In this image, Summasounds is playing a concert! This image is great to show how sound is produced. If it is possible to see, behind Pablo, there are two amps on top of each other. Also, there is an amp behind Vlad, infront of the drums. These amps are the reason sound is possible to hear throughout a venue like Pipeline Cafe. When a string is plucked, the vibration causes sound waves which we hear through the amp. The cables which connect the guitars to the amps make the sound waves travel to the amps which cause a louder sound than we would hear without the amps. In a concert like ours, there are mics for different instruments, that connect to amps all over the concert hall. For instance, there are mics by the drums I am playing on, in order to produce the volume of sound similar to the guitars, the base, and the piano. Without amps, the sound we would hear at concerts would not be very loud and equal for each instrument.
