A method of configuring an in-the-ear (ITE)
hearing aid placed within an
ear canal of a user, the method comprising receiving, by at least one input
transducer of the ITE
hearing aid, a first direct sound from a first audible sound at a first angle with respect to a horizontal plane of the
hearing aid, and a first reflected sound from the first audible sound reflected by a pinna of the user, the first direct sound and the first reflected sound having a first
delay between the first direct sound and the first reflected sound; receiving, by the at least one input
transducer, a second direct sound from a second audible sound at a second angle with respect to a horizontal plane of the hearing aid, and a second reflected sound from the second audible sound reflected by the pinna of the user, the second direct sound and the second reflected sound having a second
delay between the second direct sound and the second reflected sound, wherein the second angle is different from the first angle; determining, by a
processing unit of the ITE hearing aid, based the first
delay, a first incidence angle of the first direct audio and, based the second delay, a second incidence angle of the second direct audio; and configuring, by the
processing unit, based on the first incidence angle and the second incidence angle,
beamforming of the hearing aid.
