When performing microphone measurements, all obstacles that may disturb the sound field around the microphone are removed. The microphone may even be suspended by thin wires to ensure that the influence of a mic stand is avoided. In real life, some microphones are managed somewhat differently, handheld microphones in particular. Some artists even prefer to cover most of the microphone grid with their hand (“cupping”). This habit affects the performance of the microphone. This paper presents measurements of the influence of five different hand positions on handheld vocal microphones. Both frequency response and directivity are measured.
