ACTIVE ACOUSTIC FILTER WITH LOCATION-BASED FILTER CHARACTERISTICS

摘要

There is disclosed active acoustic filter systems and methods. A processor is disposed within a housing configured to interface with a user's ear. A memory stores data defining one or more locations and a respective set of location-based processing parameters associated with each of the one or more locations. A personal computing device external to the housing is coupled to the processor via a first wireless communications link. The personal computing device determines a current location of the active acoustic filter system. The processor generates digitized processed sound by processing 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 as determined by the personal computing device.

1. An active acoustic filter system, comprising:
an active acoustic filter configured to convert ambient sound experienced by the active acoustic filter system into digitized ambient sound; a memory 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 a 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 active acoustic filter at a particular location; and a processor configured to generate 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 a current location of the active acoustic filter, wherein the active acoustic filter is configured to convert the digitized processed sound into processed output sound, wherein the processed output sound is a modified version of the ambient sound experienced by the active acoustic filter that is processed based on the current location of the active acoustic filter.
