準データfとも第2のデジタル比較器7で比較される。On the other hand, the transmission sound b via the variable volume adjuster 2 and the amplifier 3
' is converted into digital audio data d by the AD converter 4. This digital audio data d is compared with the lower limit volume reference data e outputted from the CPU 5 in a first digital comparator 6, and also compared with the upper limit volume reference data f outputted from the CPU 5 in a second digital comparator 7. be done.
もし送話音すの音量が低くデジタル音声データdが下限
音量基準データeより小さければ第1のデジタル比較器

量を調整設定する。In the case of inputting the lower limit comparison data g, the CPU 5 outputs voice volume control data i in the direction of increasing the volume of the voice tones corresponding to that data, and in the case of inputting the upper limit comparison result data h, the CPU 5 generates voice volume control data i in the direction of increasing the volume of the voice tones corresponding to that data. Transmission volume control data i in the direction of lowering the volume of the transmission sound is sent to the volume variable adjuster 2 to adjust and set the volume of the transmission sound.
