Abstract

The proposed methodology of auto adaptation of the mobile device characteristics for various acoustic conditions was presented in the paper. The main purpose of this study was to determine the parameters of the acoustic path of the mobile device for both transmitting (speaker) and receiver (microphone). Results of the measurement characteristics of mobile devices were presented. Information about characteristics of the particular partials of the sound path were used to design and develop a technique of linearization of the device frequency response characteristics. Preliminary results obtained with the proposed methodology are presented. The performed research evolved into the design of an adaptive self-linearization method that compensates for the changing of acoustic conditions through continuous monitoring and regulating the audio settings.
