Abstract
A method for masking an acoustic stimulus, comprising: detecting an event initiated by a user of a personal audio device, the event having an associated audio artefact; in response to detecting the event, applying the acoustic stimulus to the user's ear during a masking period in which the acoustic stimulus is masked in the user's hearing by the audio artefact; extracting, from a response signal of the user's ear to the acoustic stimulus, one or more features for use in a biometric process.
