Determining in a wireless telecommunication switching system a base station on which a wireless handset is registered and using information concerning background noise at the location of the base station to automatically adjust the ringer and voice volumes for each call received by the wireless handset while registered on that base station. Further, the wireless telecommunication switching system automatically adjusts the voice volume when a call is handed off from one base station to another base station. Each base station may automatically determine the amount of background noise and transmits this information to the wireless telecommunication system controller which stores this information for future use. Also, each time a user of a wireless handset adjusts the volume of the handset, this information may be transmitted to the wireless communication switching system controller which stores the information as a preference for the user in the area served by that particular base station. In addition, the system administrator may determine the background noise for each base station and does so for different times of day. Finally, the system administrator may determine the noise level for the different areas of the building and as base stations are added to the wireless telecommunication system, they inherit the attributes of the area where they are placed.
