Abstract
solution for recreating the natural sound reception of the open ear while wearing earphones exists. It is achieved by mounting microphones on the outside of earphones, and simultaneously record and playback the sound. The solution could potentially be used for augmented audio applications. Due to practical limitations, such as the size of the earphones and microphones, it is not possible to record the sound in the ideal position. This paper presents work on finding the best position of a microphone with the purpose of reproducing as much of the spatial information as possible. The results from measurements with an artificial ear show that all spatial informations can be reproduced up to around 5-6 kHz. Above this frequency deviations in the reproduced sound, compared to the natural, is introduced. A method to evaluate how the deviations in the reproduced sound affect the listening experience is also proposed
