1. A method for estimating an effective in-ear sound pressure level of an ear canal for an individual, the method comprises:
capturing a baseline outer-ear sound pressure level outside the ear canal;
capturing a baseline in-ear sound pressure level at an intermediate position of the ear canal;
determining a correction factor by identifying a predetermined filter and a standing-wave minimum frequency according to a difference between the captured baseline in-ear sound pressure level and the captured baseline outer-ear sound pressure level, while the ear canal is unoccluded;
after determining the correction factor, capturing a first sound pressure level at the intermediate position of the ear canal; and
converting the captured first sound pressure level in an equivalent tympanic sound pressure level according to the determined correction factor.
