Abstract

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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 127 words
A microphone arrangement comprising at least two individual microphones arranged in proximity to each other, said individual microphones depending on the recording angle desired for sound recording are at least one of a pressure, a pressure gradient receiver, or a directional line microphone, characterized in that the wind pressure is continuously measured during the sound recording by means of a microphone (Mw) with a downstream switched electronic circuit (5, 11, 12) and depending upon the respectively prevailing wind pressure one microphone of said at least two microphones always remains connected by means of an instantaneously controlled switch (6, 7, 8) to an amplifier (9) and said microphone corresponding to a conversion principle, frequency response and directionality is least sensitive to wind noises at the prevailing wind intensity.
Claim 2
Dependent Claim 127 words
A microphone arrangement comprising at least two individual microphones arranged in proximity to each other, said individual microphones depending on the recording angle desired for sound recording are at least one of a pressure, a pressure gradient receiver, or a directional line microphone, characterized in that the wind pressure is continuously measured during the sound recording by means of a microphone (Mw) with a downstream switched electronic circuit (5, 11, 12) and depending upon the respectively prevailing wind pressure one microphone of said at least two microphones always remains connected by means of an instantaneously controlled switch (6, 7, 8) to an amplifier (9) and said microphone corresponding to a conversion principle, frequency response and directionality is least sensitive to wind noises at the prevailing wind intensity.
Claim 3
Dependent Claim 19 words
Microphone arrangement according to claim 1, characterized in that the microphone measuring the wind pressure is a pressure receiver.
Claim 4
Dependent Claim 24 words
Microphone arrangement according to claim 1, characterized in that the microphone measuring the wind pressure is a pressure gradient receiver with cardioid-shaped directional effect.
Claim 5
Dependent Claim 29 words
Microphone arrangement according to claim 1, characterized in that the microphone measuring the wind pressure is one microphone of the at least two individual microphones of the microphone arrangement
