A method of estimating an individualized head-related transfer function and an individualized interaural time difference function of a particular person, comprises the steps of: a) obtaining a plurality of data sets comprising a left and a right audio sample from in-ear microphones, and orientation information from an orientation unit, measured in a test-arrangement where an acoustic test signal is rendered via a loudspeaker and the person is moving the head; b) extracting interaural time difference values and/or spectral values, and corresponding orientation values; c) estimating a direction of the loudspeaker relative to the head using a predefined quality criterion; d) estimating an orientation of the orientation unit relative to the head; e) estimating the individualized ITDF and the individualized HRTF. A computer program product may be provided for performing the method, and a data carrier may contain the computer program.

A sonar based sensor for localization of a target in air is described. The sensor comprises a wide or ultra-wide band emitter for emitting a wide or ultra-wide band signal, and a set of spatially randomly or irregularly positioned receivers for receiving the wide or ultra-wide band signal after reflection at the target. A corresponding processor and method for localizing also is disclosed.
