In recent years, the importance of Head Related Impulse Responses (HRIRs) for psychoacoustic experiments and especially for studies in directional hearing has been growing, mainly caused by the availability of fast computers and the resulting possibility of very realistic dynamic binaural synthesis (cf. Mailer [1], Volk et al. [2]). A necessary prerequisite for all these methods is the correct measurement of HRIRs. In this contribution a setup will be presented which is capable of measuring HRIRs for psychoacoustic research by two different techniques: Maximum Length Sequences (MLS, invented by Schroeder [3]) and Exponential Sine Sweep (ESS, early work by Craven et al. [4] and Griesinger [5]). To reduce the measurement time, an interpolation algorithm can be used. The resulting HRIRs are compared by typical physical parameters as well as judged in a localization experiment. Based on these data, parameters for high quality HRIR measurements for psychoacoustic research are proposed.
