    Abstract: PROBLEM TO BE SOLVED: To automatically adjust the microphone gain of a communication device based on a noise level. SOLUTION: A cellular phone 100 includes a control unit 108, a digital signal processor (DSP) 110, a transmitting/receiving unit 112 and a microphone gain control unit 113. The cellular phone 100 is provided with capability of automatically adjusting the gain of a microphone 102 based on a detected noise level. As the noise level increases, the gain of the microphone 102 automatically decreases, thereby a natural tendency that the user of the telephone 100 speaks in a loud voice in noisy environment is compensated. Further, the cellular phone 100 includes a speaker 104 and the gain of the speaker 104 is adjusted so as to be increased in response to the increase of background noise level.

    Abstract: PROBLEM TO BE SOLVED: To provide a means for adjusting the gain of a microphone of a telephone based on a detected noise level. SOLUTION: Based on the detected noise level in which a cellular telephone 100 is operated, the capability for automatically adjusting the gain of a microphone 102 is included. As the noise level increases, the gain of the microphone 102 automatically decreases, thereby compensating for the natural tendency of users of a telephone 100 to speak more loudly in noisy environments. A digital signal processor 110, which is configured or programmed to apply the detected noise level to look-up tables 116 and 118 relating gain levels of a speaker 104 and microphone 102 appropriate to various noise levels, is included. The gain of the speaker 104 is adjusted to increase in response to an increase in a background noise level. Therefore, for example, no manual volume control button is needed on the cellular telephone 100. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To automatically adjust a speaker gain in accordance with a noise level by removing voice distortion of a mobile telephone. SOLUTION: When a distortion level of a frequency of a signal exceeds a predetermined value, in a speaker 414 of a mobile telephone, the frequency is filtered by an output filter 402, the signal is further compressed by a compressor 406, and the signal is then supplied via a volume setting logic 410. Furthermore, a gain of the speaker 414 is adjusted to increase the gain in response to increase of a background noise level by a means 408 for setting the background noise level in the environment, in which the mobile telephone is operating, and setting the gain of the speaker based upon the detected background noise level. Thus, voice quality is improved, a volume control button of a telephone is not required, and configuration can be simplified. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: In one embodiment, a mobile station such as a dual-mode, AMPS and CDMA, handset communicates with an AMPS base station in a wireless communication system. The mobile station includes an acoustic echo canceller, which can detect acoustic echo, for example, feedback from the handset speaker to the handset microphone, during communication between the mobile station and the base station, and cancel or eliminate the acoustic echo. The mobile station also includes a network echo suppressor coupled to the acoustic echo canceller. For example, the network echo suppressor can read a parameter set by the acoustic echo canceller. The network echo suppressor attenuates or mutes a network echo caused by portions of the communication returning to the mobile station from the base station after a network propagation delay. Coupling the network echo suppressor to the acoustic echo canceller ensures proper interaction between the network echo suppressor and acoustic echo canceller.
