It is intended to be able to manufacture multiple microphones for realizing highly reliable directional microphones for hearing apparatuses, and in particular for hearing devices, in a simpler manner. To this end, provision is made to develop at least two silicon microphones and at least two impedance converters connected thereto on one single chip, thereby producing an integrated circuit. In particular, twin and triplet microphones can be realized for hearing devices, which exhibit an increased reliability and a reduced sensitivity to environmental influences. Special advantages result for the one chip multiple microphones when they are designed as SMD assemblies.
