The results of some research projects during the last years improved our understanding of three-dimensional hearing of men. In this paper after a more general review of this topic some more interesting details are discussed which lead to technical applications or are likely to do so in the near future. Such applications are: Suppression of reverberation in electroacoustical trans- mission systems, dummy head stereophony, measurement of ear-drum-im- pedance and the area function of the ear canal with respect to medical diagnostics. 57 Neuere Ergebnisse zum raumlichen Horen (a) Ubliches Blockdiagramm einer N achrichtenubertragungss trecke r------------i I I I I I I I I QueUe Sender Kanal I Empfanger Senke: L ____________ ..J Storsignale (b) Spezialfa!1: Elektroakustische Ubertragung ( Empfangsseite ) r-------------------------------, I I I I I I I I I: Empfanger Wandler..
