摘要： An audio enhanced hearing protection system to be worn by a user includes an ambient noise reduction assembly having a primary noise reduction unit and a secondary noise reduction unit. The audio enhanced hearing protection system also includes an audio input assembly having one or more environmental microphones to receive raw environmental audio signals. The raw audio signals are transformed into processed audio signals via a digital signal processing assembly prior to transmission to a user. The audio enhanced hearing protection system also includes an audio output assembly having at least one speaker to transmit processed audio signals to a user.

摘要： A system and method for digital processing including a gain element to process an input audio signal, a high pass filter to then filter the signal and create a high pass signal, a first filter module to filter the high pass signal and create a first filtered signal and a splitter to split the high pass signal into two high pass signals. The first filter module filters one high pass signals before a first compressor modulates the signal or a high pass signal to create a modulated signal. A second filter module filters the modulated signal to create a second filtered signal that is processed by a first processing module including a band splitter that splits the signal into low and high band signals that are then modulated by compressors. A second processing module processes the modulated low and high band signals to create an output signal.

摘要： The present invention provides methods and systems for digitally processing audio signals in two-channel audio systems and/or applications. In particular, the present invention includes a first filter structured to split a two-channel audio input signal into a low frequency signal and a higher frequency signal. An M/S splitter is then structured to split the higher frequency signal into a middle and a side signal. A detection module is then configured to create a detection signal from the middle signal, which is used in a compression module configured to modulate the side signal to create a gain-modulated side signal. A processing module is then structured to combine the low frequency signal, middle signal, and the gain-modulated side signal to form a final output signal.

摘要： The present invention provides methods and systems for digitally processing audio signals in broadcasting and/or transmission applications. In particular, the present invention includes a pre-transmission processing module which is structured and configured to generate a partially processed signal. A transmitter is then structured to transmit or broadcast the partially processed signal to a receiver, where the signal is then fed to a post-transmission processing module. The post-transmission processing module is structured and configured to further processes the signal based upon, for example, the listening environment, profile(s), etc. and generate a final output signal.

摘要： The present invention relates to a noise reduction assembly for auscultation of a body. An embodiment of the assembly includes an auscultation device formed of a first material and having a proximal end for engagement with the body when the auscultation device is in an operative orientation. An interior dampening layer, which may be formed of a second material, is formed along an exterior surface of the auscultation device and covering all exterior surfaces thereof except the proximal end. An exterior dampening layer, which may be formed of a third material, is then formed in covering relations relative to the interior dampening layer.
