Abstract
There is provided an ear cup including a housing containing a filter assembly and a motor-driven impeller for creating an airflow through the filter assembly, the housing including an air outlet downstream from the filter assembly for emitting the filtered airflow from the housing. The ear cup further includes an acoustic driver carried by the housing, a reference internal noise sensor carried by the housing, and active noise control circuitry that is configured to use a signal provided by the reference internal noise sensor to operate the acoustic driver.
