Abstract
A microphone arrangement comprising at least two individual microphones arranged closely next to each other, whose individual microphones depending on the recording angle desired for the sound recording are a pressure- and/or a pressure gradient receiver and/or a directional line microphone, is characterized by the wind pressure being continuously measured during the sound recording by means of a microphone (Mw) with downstream switched electronic circuit (5, 11, 12) and depending on the respectively prevailing wind pressure always that microphone (M1, M2, Mn) remains switched to the amplifier 9 assigned to it by an instantaneously controlled switch (6, 7, 8), which in its conversion principle, frequency course and its directional effect is least sensitive to wind noises for the prevailing wind intensity.
