Claim Text:
1. An active acoustic filter system, comprising: a housing configured to interface with a user's ear; a microphone, a preamplifier, and an analog to digital converter to convert ambient sound experienced by the housing into digitized ambient sound; a processor disposed within the housing; a memory disposed within the housing and storing data defining one or more locations and a respective set of location-based processing parameters associated with each of the one or more locations, wherein at least one set of the one or more sets of location-based processing parameters were manually entered by the user at least in part by the user inputting one or more inputs that adjust a decibel level associated with one or more user selected frequency bands of an audible frequency spectrum associated with ambient sound experienced by the housing and wherein the one or more inputs are stored in the memory in association with the respective set of location-based processing parameters and a location of the active acoustic filter; and a digital to analog converter, an amplifier, and a speaker to convert digitized processed sound into processed output sound, wherein a personal computing device is external to the housing and coupled to the processor via a first wireless communications link, the personal computing device is configured to determine a current location of the active acoustic filter system, wherein the processor generates the digitized processed sound by processing the digitized ambient sound in accordance with a set of location-based processing parameters retrieved from the memory, the retrieved set of location-based processing parameters associated with the current location of the active acoustic filter system, and wherein the processed output sound is a modified version of the ambient sound experienced by the housing that is processed based on the current location of the active acoustic filter.
