> Humans in general are very sensitive to sounds within 2kHZ-5kHz range. If the frequency of a virtual sound doesn’t match up to what we expect it to be in reality, then we are more likely to identify the sound as “not real”. This is particularly true if you compare how easy it is to tell if someone’s voice is broadcast through a speaker vs. someone is talking beside you.

I never thought about that in regards to gaming or even conference room voice chat, it is extremely easy to tell the difference. Must be a challenging problem set to solve, sounds fun!
