Manufacturers of sound level meters have need to measure the random incidence frequency response of the microphone used on that product. This paper describes a method of making this measurement without the need for an anechoic or large reverberant room. A reverberant box is used to directly determine the random incidence response of the microphone at high frequencies with a coupler measurement being substituted for reverberant measurement at low frequencies. The techniques and equipment are discussed in detail.
