Abstract :
This paper addresses the problem of measuring the acoustic frequency response of auditoria and loudspeaker characterization. The difficulty of the problem is illustrated with a number of measurements performed using different methods and equipment. The use of multitone signals both uniformly and logarithmically spaced is proposed to obtain fast and reproducible measurements
