Answer:
We know where a sound is coming from based off of how loud the sound is and which ear we hear the sound in first
Step-by-step explanation:
The vibration of a noise loses energy as it travels through the air. As it loses energy, it becomes quieter. This allows us to know how far away a noise is.
Our brains can tell where a sound is coming from based off of which ear it reaches first. If it reaches our left ear first, the noise is coming from our left. If it reaches our right ear first, it’s coming from the right.
