ELI5: How are we able to hear more than 1 sound at the same time?

How can I hear two sounds at the same time when my eardrum can vibrate at only 1 frequency at a time? How can my brain decipher that 1 frequency into its component sounds?

Because we aren't just able to pick up one frequency at a time as such. All the frequencies mix together ( as it's all moving air) and it produces sort of a frequency that keeps changing rapidly and that's what makes up the sound we hear.
