This is an invention for automating the volume settings of a communication device (110) such that the device (110) does not need a dedicated volume control. After a voice traffic channel has been established, but prior to the use's speaking, the ambient noise energy level and the incoming signal level, when speech is detected, are measured. At least one of the measured levels are utilized in an algorithm function (210) to index a lookup table (225). The lookup table (225) contains output amplifier adjustment values initially based on ranges of at least one of the measured levels. The output amplifier adjustment values are utilized by the output amplifier (240) to amplify or attenuate the incoming receiver audio signal to an automatic volume setting. |
