This noise compensation application, when executed by the processor, configures the control circuit to: receive an input from the detector, detect a frequency of the input, compare the frequency with a selected one of the settings, and selectively filter the ambient noise when the detected frequency is within a prescribed range. | 2012-08-09 |
20120201394 | AUDIO DEVICE VOLUME MANAGER USING MEASURED DISTANCE BETWEEN FIRST AND SECOND AUDIO DEVICES TO CONTROL VOLUME GENERATION BY THE SECOND AUDIO DEVICE - An audio volume control method employs an audio system that includes a first audio device and a second audio device. A communications link connects the first and second audio devices together so that each may communicate with the other. The system includes an audio volume manager that varies the audio output level of the second audio device as a function of the perceived loudness of the second audio device as perceived at the first audio device. To determine the perceived loudness of the second audio device as perceived at the first audio device, the audio volume manager may measure the current distance between the first and second audio devices. | 2012-08-09 |
20120201395 | METHOD AND SYSTEM FOR CONTROLLING A MAXIMUM SIGNAL LEVEL OUTPUT TO HEADPHONES COUPLED TO A WIRELESS DEVICE - A method for controlling a maximum signal level output to headphones of a wireless device is provided. The method includes: determining an impedance of the headphones; determining a carrier specific maximum signal level for headphones having the impedance; and, adjusting an audio amplifier of the wireless device coupled to the headphones to restrict the maximum signal level output to the headphones to the carrier specific maximum signal level. | 2012-08-09 |
