Embodiment Construction

[0061] What is shown in the figure is schematic. Note that in different drawings, similar or identical elements have reference numerals that differ from the corresponding reference numerals only by the first digit.

[0062] figure 1 An audio device 100 according to the invention is shown. According to the embodiment described here, the audio device is a mobile phone 100 . The mobile phone includes an acoustic output device 110 and an acoustic input device 120 . The acoustic output device is a speaker 110 and the acoustic input device is a microphone 120 . The speaker 110 is driven by the audio output signal x'(t). The audio output signal x'(t) is generated by the loudness enhancement unit 111. The audio output signal x'(t) is generated based on the original audio signal x(t) fed to the loudness enhancement unit 111. According to the embodiment described herein, the original audio signal x(t) and the audio output signal x'(t) represent the ring tone of the mobile phone 10...

Abstract

Described is a method for controlling an adaptation of a behavior of an audio device (100) to a current acoustic environmental condition. The method comprises (a) monitoring an audio output signal (x(t), x'(t)) being provided to an acoustic output device (110) of the audio device (100) for outputting an acoustic output signal, (b) measuring an audio input signal (z(t)) being provided by an acoustic input device (120) of the audio device (100), wherein the audio input signal (z(t)) is indicative for a feedback portion of the acoustic output signal and for the current acoustic environmental condition, (c) determining a relation between the audio output signal (x'(t)) and the audio input signal (z(t)) and (d) adapting the behavior of the audio device (100) based on the determined relation. Further, it is described a data processor, a computer-readable medium and an audio device, which are adapted to control and / or to carry out the above mentioned method for controlling an adaptation of the behavior of an audio device (100) to a current acoustic environmental condition.

Description

technical field [0001] The present invention relates to the technical field of controlling an audio system comprising an acoustic output device such as a speaker and an acoustic input device such as a microphone. In particular, the invention relates to a method for controlling the adaptation of an audio output signal of an audio device to the current acoustic environment conditions of the audio device. Furthermore, the invention relates to a data processor, a computer readable medium and an audio device adapted to control and / or execute the above-mentioned method for controlling an audio output signal to adapt the audio device to the current acoustic environment conditions of the audio device. Background technique [0002] Depending on the usage of the mobile device, such as a mobile phone, the desired level requirements for an audio playback signal or a ring tone indicating an incoming call or incoming Short Message Service (SMS) are different. For example, when indoors in...
