Measurement of a Binaural Room Impulse Response with High Peak-to-Noise Ratio

During their measurement, binaural room impulse responses (BRIRs) are impaired by equipment and background noise. The resulting noise floor might become perceptible when BRIRs are used for auralization purposes, i.e. by convolution with a dry source. To avoid the audibility of noise, high peak-to-noise ratio BRIRs are desired. A high peak-to-noise ratio (PNR) can be computed by averaging of multiple measured BRIRs. With this measurement at least a 90 dB PNR-BRIR is aspired. The published data set contains the sweep signal as excitation signal, the captured room responses as raw-data which are measured from the frontal and the lateral side in two sessions each and the resulting binaural room impulse responses. Additionally, the computed averaged high-PNR-BRIRs and the high-PNR-Raw-Data are included.
