ITU-T G.720 FRENCH-1995 带有非话音信号的低速率数字话音信号编码器性能的特征.数字传输系统的一般性质.15号研究组.19pp

This Recommendation encompasses methods that can be used for quantifying and characterizing the performance of low-rate digital speech codecs with non-voice signals. The signals used are primarily those employed within the telephone network and, consequently, these methods are most appropriate for speech codecs intended for network (as opposed to end-user terminal) applications. The methods presented here can be used to quantify the performance of voice codecs that operate in the telephone band and that employ transmission rates that are less than or equal to 64 kbitfs.

This part of ISO 389 specifies the following data applicable to the calibration of bone vibrators for puretone bone-conduction audiometry. a) Reference equivalent threshold force levels (RETFLs), corresponding to the threshold of hearing of young otologically normal persons by bone-conduction audiometry. RETFL is the vibratory force level transmitted to a mechanical coupler of specified characteristics (see 5.3) by a vibrator when applied to the mechanical coupler under stated conditions of test and when energized at the voltage level corresponding to the normal threshold of hearing for location on the mastoid prominence. NOTE 1 Interim values for the differences in reference equivalent threshold force levels between location on the forehead and mastoid are included for information in Annex C. b) Essential characteristic of the bone vibrator and of its method of coupling to a person under test and to the mechanical coupler. c) Essential characteristics and datum level of the masking noise applied to the ear not under test. Guidance on the practical application of this part of ISO 389 in the calibration of audiometers is given in Annex B. NOTE 2 Recommended procedures for carrying out bone-conduction audiometry are specified in ISO 8253-1.
