In human localization play the outer ears and the shape of the human body a significant role. Little modifications of the acoustical environment near to the listeners' head have significant effects on the transfer functions (HRTFs). This work analyses the transmission of the directional information and contributes to the suggestions of the physiological hypotheses based on the role of the HRTFs. Microphones are placed at the eardrums of a dummy-head, and accurate measurements will be performed. First, a good quality binaural playback system is tested using equalized headphones and HRTF filtering in order to find well-known errors and the localization blur. The second part introduces an accurate dummy-head measurement system with increased precision, signal-to-noise ratio and reproducibility. Finally, the HRTFs in the frequency domain and the effect of the acoustical environment near to the head will be evaluated (effects of the "everyday objects" near to the head). In the discussion section we try to specify the quality levels of existing binaural systems and the role of the HRTFs in virtual and non-virtual environments during the decoding of the acoustical information.}, subject = {Tonstudiotechnik; Binaurales H{\"o}ren; Richtungsh{\"o}ren; Raumakustik; Signal-Rausch-Abstand; {\"U}bertragungsfunktion; HRTF; Acoustic; Dummy-head; Headphone; Localisation}, language = {en} }
