Okay kiddo, listen carefully, I'll explain what ghost-canceling reference means. When we hear a sound, it's because it travels through the air and hits our ears. But sometimes, there might be more than one sound hitting our ears at the same time, and that can make it hard to understand what's being said or heard.
Now imagine that you're trying to listen to a recording of someone talking, but there's also a lot of background noise. This background noise can be like a ghost, sneaking into your ears and messing up the sound you really want to hear. This is where ghost-canceling reference comes in to help.
Ghost-canceling reference is like a special tool that can help us get rid of the ghost sounds. It does this by listening to the sound waves that are coming from different directions and at different times, then finding the ones that are causing problems and canceling them out.
It's kind of like if you were playing with building blocks, but some of them were wobbly and didn't quite fit with the others. Your ghost-canceling reference would help you find those wobbly blocks and remove them so that you can make a nice, neat tower.
So, in short, ghost-canceling reference is a way to get rid of unwanted sounds that might be interfering with the sounds we really want to hear. It's like a special tool that helps us listen better!
