Abstract
The present invention relates to a method for use in an earphone or headset system, said system comprising at least one sound reproduction transducer (341), at least one microphone (101) arranged to pick up ambient sound signals, and a processor arranged to process at least one of - at least one electronic sound signal obtained by an electronic source input (201) and/or - said ambient sound signals, wherein said method employs an arrangement of said processor to process said signals so that time varying characteristics of one of said signals may modify a processing of an other of said signals prior to reproduction via said sound reproduction transducer (341), characterized in that said processor - determines an estimate of an acoustic transfer function of a leakage path (510) between the environment and an ear cavity of a wearer of said system, - employs said estimate of said acoustic transfer function to estimate a level of ambient sound reaching an eardrum of said wearer of said system, and establishes settings for said processing of said signals on the basis of said estimate of said level of ambient sound reaching said eardrum.
