I'm working on a DPS software and I was looking at the entire time that my sound sample take from the moment it begin the processing until it reach the ear. I'm reaching something like 71ms, but I've no reference which could allow me to say if it's good or not.
So I was wondering : how many time does the sound take to reach the human ear since the moment where the hammer of a piano touch the wire ? I'm not talking about sound speed but the moment when we ear the piano key.
