So , Sound travels by vibration , but vibration is only a one dimensional motion. Left and right. So the air molecules only move towards the left or right. So the sound wave only propagates left or right. But what if we are perpendicular to the oscillation. How do we hear sound?

vibration is only a one dimensional motion

This is not generally true. As a trivial example, one could the movements of water in a pond where a few small rocks have been tossed. The motion is definitely a wave behavior, and could even be called vibration, but it is most definitely not one dimensional.

Another potential example would be the vibrator on your phone, which vibrates in a circular manner.

But in the end, the key is that atoms in a sound wave don't vibrate "left and right." They are a longitudinal wave, in which particles move in the direction of the wave's motion and back.

So when something causes a sound, the waves propagate outward from the object creating the sound, as molecules of gas move away from the source and towards the source. This is typically a 3 dimensional pattern

Sound wave is not a transverse wave, as you thought. That means the vibration and the direction of propagation for sound wave are parallel. And the vibration is caused by difference in air pressure at different places. To the question "how I can listen to it" thats because the pressure difference propagates toward your ear and force your eardrum to vibrate.
