Abstract: The present disclosure provides a method for evaluating an electronic device. The method comprises determining, with an acoustic tube, a value of a first parameter, the value of the first parameter being indicative of the acoustic impedance of a reference termination. The method further comprises determining, with the acoustic tube, a value of a second parameter, the value of the second parameter being indicative of the acoustic impedance of the reference termination, when occluded by the electronic device. The method then comprises calculating a value of a third parameter, the value of the third parameter being indicative of the acoustic impedance of the electronic device, based on the value of the first parameter and the value of the second parameter.

Abstract: An apparatus provides personalized binaural audio rendering of an input signal. The apparatus has a left ear transducer configured to generate a left ear audio signal and a right ear transducer configured to generate a right ear audio signal. Moreover, the apparatus has processing circuitry configured to determine, based on a current target direction of the input signal, an adjusted current target direction using a personalized adjustment function that describes a functional relationship between a plurality of reference target directions of a reference sound signal and a plurality of perceived reference target directions of the reference sound signal as perceived by a user. The processing circuitry is further configured to implement a target direction renderer configured to generate based on the input signal and the adjusted target direction a first driving signal for driving the left ear transducer and a second driving signal for driving the right ear transducer.
