The invention relates to a method and device for generating data about the
mutual position of at least three acoustic transducers. The aim of the
invention is to make it possible to continuously measure and calculate
the mutual position of at least three acoustic transducers, particularly
the rotation and the position of a human head wearing headphones within a
room without using any additional transmitter element on the head,
headphone, or body of the listener, during audio playback. This aim is
achieved by connecting the acoustic transducers to a digitally operated
system which comprises an output path emitting audio signals to first and
second acoustic transducers, an input path receiving audio signals from
the third acoustic transducer, an audio signal source that is connected
to the output path, an ultrasound generator that is connected to the
output path, and an information generator which indicates a position and
is connected to the input path.
