Abstract: Microphone array which comprises a multiple of microphones which are arranged in an elongated element or housing, in which the individual microphones in the microphone array are arranged in pairs. The individual microphones in each pair are disposed on each their side of a centerline for the microphone array, where the signals from the microphones are summated in the formation of the output signal from the microphone array. The microphones on each side of the centerline of the microphone array are disposed with non-equidistant spacing between them, and low-pass filters are coupled between each microphone and a summation link, in that the microphones associated with one and the same pair are connected to low-pass filters having the same cut-off frequency. The cut-off frequency for the low-pass filters is different for each pair of microphones, in that the cut-off frequency is lowest for that pair of microphones which lie furthest away from the centerline, and is higher the closer the pair of microphones lies to the centerline. The microphone array is arranged in such a manner that the distances between the microphones and the cut-off frequencies for the low-pass filters are mutually adjusted in relation to one another.

Abstract: A system for estimating the occlusion effect comprises a hearing aid adapted for being set up for operation in an occlusion measurement mode. The hearing aid comprises a first transducer (9) for transforming an acoustic sound level external to a hearing aid user's ear canal into a first electrical signal. The hearing aid comprises a second transducer (10) for transforming the acoustic sound level in the occluded ear canal into a second electrical signal. The system comprises a filter bank (21, 22) for splitting the first and the second digitized electrical signals into a first and a second band split digitized electrical signal, respectively and the estimated sound pressure must be a factor √{square root over (r)} larger than the estimated leakage when deciding if the estimated sound pressure in a given band can be applied in the calculation of the occlusion effect. The invention further provides a method for estimating the occlusion effect.
