The feedback of recording engineers to condenser microphones occasionally refers to them as “hearing too far.” Unwanted background noises such as fans, clocks, air conditioners that are not heard when recording with a dynamic microphone are being reproduced by a condenser microphone. In the present study this phenomenon is examined in regard to its physical cause. The whole signal chain from the microphone to the recorder has to be considered. Therefore it needs to be determined how the masking effect and the perceptibility of quiet sources are influenced by the self-noise of the signal chain.
