A calibrated noise-data-base, which consists of a calibration signal and an optimal selection of 23 different noises, is available. This data-base was earlier provided on a CD which is not available any-more.
The use of the data-base is described in two papers in:
Steeneken, H.J.M. and Varga, A. (1993) “Assessment for automatic speech recognition I: Comparison of assessment methods”, Speech Communication 12 (1993). nr. 3, pp. 241-246, 1993 P39.
Varga, A. and Steeneken, H.J.M. (1993) “Assessment for automatic speech recognition II: NOISEX-92: A database and an experiment to study the effect of additive noise on speech recognition systems”. Speech Communication 12 (1993), nr. 3, pp. 247-251 1993 P40.
In general each signal has a duration of aprox 4 minutes, sample rate 20 kHz, word-length 16 bit and is stored according the .wav format.
The contents of the database are described in: RSG-10_Noise-data-base. This report has three annexes respectively:
