[A testing arrangement for spatial hearing].
A test-situation which concerns the spatial character of hearing is demonstrated. The subject indicates the estimated location of the stimulus. The WN is presented at a short distance from the head and thus discrepancies in distance can also be discriminated. The subjective space of man (polar system of coordinates) consists of three dimensions (horizontal, vertical and distance equals radius); for each of these three dimensions the average shift of the centre and the standard deviation (representing the error) are calculated. When testing lateral (45 degrees right or left) the average error is a little smaller for the horizontal scale than for the vertical. As far as the distance is concerned the results of the 21 subjects varied considerably; while some of the persons showed surprisingly good location ability, others supposed the noise to come from even outside the camera silens. The investigation has been carried out to contribute to the exploration of subjective acoustic space. It is also planned to apply the test as a diagnostic procedure in various neurological disturbances.
