Abstract
An active noise cancelling system () comprising: an earphone (') comprising: an electro-acoustic driver (); and at least one sensing microphone (); tunable active noise cancelling circuitry () operative to receive a signal from the at least one sensing microphone (), the tunable active noise cancelling circuitry () being pre-configured in a standard tuning for a reference ear and comprising at least one noise-control filter (); and a tuning module () operative to configure the earphone (′) for an individual wearer by: comparing acoustic coupling of the earphone (′) to the individual wearer's ear with acoustic coupling to the reference ear to determine a deviation in acoustic coupling; and using the determined deviation in acoustic coupling to modify the tunable active noise cancelling circuitry () by a predetermined degree based on the determined deviation in acoustic coupling.
