The speed of sound in air is ~330m/s so sitting about a metre away will produce ~3ms delay. However the speed of the vibration through human flesh (far denser than air) is about 4 to 5 times faster than the speed in air. You will "hear/feel" the sound transmitted through your body far faster than the sound transmitted through air. This maybe why I'm always seeing this magical "1ms" value.
