Speech-noise test backgrounds were upgraded to match both spectral and temporal envelopes

Evidence

Therefore, a background noise for speech audiometry wa” developed simulating the average spectral and temporal envelope of “peech. The features of this background noise are illustrated in Fig, 16,38. The upper panel” show the spectral distribution and the loudness-time function of the CCITT speech noise. The solid curve in the upper left panel shows the spectral weighting with a maximum around 800 Hz in comparison to the average spectral envelope of speech for several different languages as described by Tarnoczy (hatched). — Professor Dr.-Ing.
