Measuring the frequency response of a driver mounted in an idealized infinite baffle is desirable even though the IEC specifies a finite baffle with fixed dimensions. Finite baffles confound direct radiation with diffracted radiation. Based on quantitative computations using the extended Boit-Tolstoy-Medwin technique, a correction process compensates the measured response with a finite baffle to the result that would be obtained with an ideal infinite baffle. Experimental results show the validity of the approach.
