7.7. Measurement of baffle constants

The constants of the baffle may be measured after the loudspeaker constants are known. Refer to Fig. 7.6. The quantities R _AR and X _AR are determined from Eqs. (7.31) and (7.32). The electrical and mechanical quantities are measured directly.

Measurement of C _AB

Using the same procedure as for measuring f _S and Q _EC in Section 6.10, determine a new f _C and Q _EC and solve for C _AB from Eq. (6.71) so that

C A B = V A S ρ 0 c 2 ( f C Q E C f S Q E S − 1 )

Measurement of R _AB

Using the same procedure as for measuring ...
