Direction of sound incidence
The direction of sound incidence is determined as the sound incidence angle θ in angular degrees . The sound signal is mostly viewed in the horizontal plane as it falls on a human head, on an artificial head when listening to direction , but also on a microphone system or microphone . The most important direction of sound incidence straight ahead is referred to as 0 °.
A microphone with a cardioid directional characteristic has the lowest sensitivity or greatest attenuation at 180 °, i.e. at the rear, and for a figure-of-eight microphone at 90 ° and 270 ° or + 90 ° and −90 °, i.e. on the sides.
The technical term localization has been introduced to determine the direction of sound incidence (direction determination) or the direction of the auditory event during directional hearing .
