D_Ear
Directional Hearing
The human hearing cannot distinguish sounds separated in time by less than 20-30 milliseconds (msec), but it can understand differences between the arrival times at the two ears which are much less than 1 msec. From these differences we distinguish where the sound comes from
- When the sound source lies right in front of us the time difference is 0 msec (sound reaches both ears simultaneously)
- When the sound source lies on the side the time difference is about 0.6 msec (the sound reaches the closest ear first)
- When the sound source lies somewhere in between the time difference is between 0 and 0.6 msec
In D_Ear the sense of direction is given by the difference in arrival time of a 300-Hz pulsed sound at each ear, with differences from 0 msec (front source) to 0.6 msec (source on the side).
Wear the headphones properly and
Enjoy!!!
