摘要： An acoustic processing module receives an acoustic signal, and outputs an analog output signal. Microphone sensors are provided for generating a corresponding electrical signal in response to the acoustic signal. A signal processing circuit is connected to the microphone sensors, and processes the electrical signals according to one or more analog signal processing functions to generate the analog output signal. An integrated casing encapsulates the microphone sensors and the analog processing circuit, and prevents external interference from affecting any electrical signals within the integrated casing.

摘要： An interface between a programming system and a set of headphones allows the transmission of both audio and digital data over analog audio signal lines of the headphones. Circuitry on the programming system is configured to transmit digital data over the analog audio signal lines by either modulating a carrier frequency with the digital data such that the digital data is transmitted over non-audible frequencies or by time-multiplexing the transmission of digital data and analog audio data. Circuitry on the headphones is configured to receive digital data by demodulating the modulated digital data or by de-multiplexing the time-multiplexed digital and analog audio data. In other embodiments of acoustic headphones which include microphones, a Talk-Through functionality may be implemented.

摘要： A system includes a plurality of inputs each configured to receive a filtered version of a source signal. The system extracts the energy information from each input signal and compares the energy information of a plurality of input signals. Alternatively, the system extracts energy information from a signal that is the difference of two input signals. Based on the energy information, the system determines at least one parameter that may be changed in at least one circuit in a plurality of circuits to minimize the differences in energy of the input signals or to minimize the energy of the difference signal. Parameters may include for example amplification, delay, and corner frequency values.The set of circuits may include microphone interface circuits. Merely by way of example, a system with microphone interface circuits may be included in a hearing enhancement device or in a hands-free earpiece.

摘要： A voltage integrator circuit and a filter circuit are configurable to adjust their outputs in order to compensate for various circuit elements' variations with temperature. The voltage integrator circuit performs temperature compensation through the adjustment in resistance value of a single resistive element in response to a received control signal. The control signal correlates with a detected temperature value and causes the resistive element to adjust its resistance value in a manner that maintains the transfer function of the voltage integrator circuit under varying temperatures. The filter circuit comprises one or more of the voltage integrator circuits and maintains its transfer function under varying temperatures.
