4.3.4.6 SPL Measurement

To measure the SPL characteristic of the speaker, connect a microphone to the learning board and make the SPL measurement according to the instructions on the Speaker Acoustic Response page.

Figure 4-13 shows the typical results of the SPL characterization on Review SPL Model page. Check the SPL results with the information from the data sheet of the target speaker, and click the Accept button to continue the characterization.
