The work presented in this paper investigates different sound sources used for microphone measurement in an anechoic room. The microphone under test is measured using three different physical impulse-like sources: balloon explosions, sounds created using wood-planks, and revolver shots and the results are compared with a measurement in which the sound is generated by a loudspeaker excited with a large band swept-sine signal. The frequency response functions of three different commercial microphones are measured and compared with the data provided by the manufacturer.
