摘要： A method includes detecting, via a first microphone coupled to a user's left ear, a sound, detecting, via a second microphone coupled to the user's right ear, the sound, determining a time difference between detection of the sound at the first microphone and detection of the sound at the second microphone, and estimating a user's head size based on the time difference. The method also includes identifying a head-related transfer function (HRTF) associated with the user's head size or modifying, a HRTF based on the user's head size. The method further includes applying the identified HRTF or modified HRTF to audio signals to produce output signals and forwarding the output signals to first and second speakers coupled to the user's left and right ears.

摘要： A hands-free unit comprises a noise tolerant audio sensor to generate a first audio signal based on detection of audible sounds and an external audio sensor to generate a second audio signal based on detection of the audible sounds. A tunable distortion reduction filter adds high frequency information to the first audio signal and reduces distortion. A control unit detects noise levels based on comparison of first and second audio signals; and selects one of the first and second audio signals based on the detected noise level.

摘要： The present invention relates to a method for determining an acoustic property of an environment. According to the method a sound signal and at least two reflection signals of the sound signal (are received, and for each of the reflection signals a time difference between a time of reception of the sound signal and a time of reception of the respective reflection signal is determined. Furthermore, for each of the reflection signals, an angle between a reception direction in which the sound signal was received and a reception direction in which the respective reflection signal was received is determined. Based on the determined time differences, the angles and predetermined constraints defining arrangement constraints of the sound reflecting surfaces an arrangement of the sound-reflecting surfaces is determined.

摘要： Noise-suppressing techniques using a dual-microphone headset include methods in which first and second audio input signals are generated from first and second microphones placed in or near a user's ears, or on each side of the user's throat. These audio input signals are correlated, to produce a correlation signal, and are also combined, to produce an intermediate audio signal. An output audio signal is generated by selectively adjusting the amplitude of the intermediate audio signal, based on the correlation signal, to emphasize correlated components of the first and second audio input signals, relative to uncorrelated components.

摘要： In a method and apparatus for power allocation used by a BTS in a mobile telephone system, an available radio power is distributed between a plurality of carriers, a request for a channel for communication (201a,201b,201c) is received. A required amount of power is requested from a power bank (202), and a check if the required amount of power is available (203) is performed. If the power is available it is allocated (204, 205), and the connection is established (206).
