Plots of these two designs are shown in Fig. 20. Of course, an arbitrary combination of DI and F could also be maximized for some given optimality criterion if desired. 6 Maximum Second-Order Differential DI and F Using Common First-Order Differential Microphones. Another approach to the design of second-order differential microphones involves the combination of the outputs of two first-order differential microphones. Specifically, the combination is a subtraction of the first-order differential outputs after one is passed through a delay element.
6. There are two main trends that can easily be seen in Fig. 6. First, the gain in directivity index decreases as the number of elements (order) is increase. Second, the difference between the maximum gains for spherical and cylindrical fields is quite sizable and increases as the number of elements is increased. 28 Audio Signal Processing The first observation is not too problematic since practical differential arrays implementation are limited to third-order. The second observation shows that attainable gain in cylindrical fields might not result in required microphone array gains for desired rejection of noise and reverberation in rooms that have low absorption in the axial plane.
84). 9 dB. 6 dB. We begin our analysis of second-order Chebyshev differential arrays begins by comparing terms of the Chebyshev polynomial and the second-order array response function. 28) yields: where L is again the sidelobe threshold level. 18(c) show the resulting second-order designs for –15 dB and –30 dB sidelobes respectively. 1 dB. Null locations for the –15 dB sidelobes design are at 78° and 142°. By allowing a higher sidelobe level than the Korenbaum design (for with a higher directivity index can be achieved.
