Claim Text:
1. An active acoustic filter system, comprising: a housing configured to interface with a user's ear; an input subsystem disposed within the housing and comprising a microphone to receive ambient sound and generate ambient sound signals, a preamplifier and an analog to digital converter coupled to one another, the input subsystem configured to convert the ambient sound signals into digitized ambient sound signals; a memory storing data defining one or more locations and a respective set of location-based processing parameters corresponding with each of the one or more locations; a geolocation engine configured to determine a current location of the active acoustic filter system; a processor disposed within the housing and coupled to the input subsystem, wherein the processor generates digitized processed sound signals by processing the digitized ambient sound signals in accordance with the set of location-based processing parameters stored in the memory which corresponds to the determined current location of the active acoustic filter system provided by the geolocation engine; and an output subsystem disposed within the housing and coupled to the processor, the output subsystem comprising a digital to analog converter, an amplifier and a speaker coupled to one another, the output subsystem configured to convert the digitized processed sound signals into processed output sounds for the user's ear through the speaker; wherein at least one of the sets of location-based processing parameters comprises a collection and average of processing parameters set by a plurality of users within the determined current location for the processing of the digitized ambient sound signals.
