How speakers can make so many different sounds at once when they only have one membrane
In: Physics
Because that’s what sound is. Sound is just the propagation of a pressure wave.
As a wave travels through the air it creates areas of high pressure and low pressure. The each part of the air can only be at a single pressure at any given time. So you can see that two waves don’t travel separately (which would create two different pressures at any given point) but instead travel together as a single wave and produce a pressure that is the sum of each ‘part’ of the wave.
This single wave hits our ear and resonates parts of it in different ways. Our brain has developed ways to ‘decode’ this single sound wave into its parts and give you the experience of multiple different sounds
