Abstract
This invention describes a mobile phone with a means of measuring a background sound level of an environment. When a user either initiates or receives a phone call, sound levels before and during the call are compared. Once it is decided that the voice is too loud based on a predetermined criteria, the phone gives the user a feedback indicating that the voice is too loud and potentially a disruption to other people. Furthermore, the present invention provides a feedback for a voice adjustment by utilizing a sidetone adaptive signal that filters the user own speech directly to an earpiece.
