The close-microphone technique is widely used in modern sound engineering practice. It is mainly used to minimize the effect of leakage and room acoustics on the received signal. In this work, the properties of the close-microphone response are investigated from a signal processing point of view, through the respective frequency domain statistical moments. Room impulse response measurements were made in various rooms and source-microphone distances and statistical moments were calculated over frequency and distance. It is shown that the statistical properties of the impulse responses remain relatively constant for short source-microphone distances and this in turn provides a consistent sound, which was validated through a subjective evaluation test.
