The large numeric readout in the upper right corner of the Smaart 7 real-time mode window, can be configured to function as a standard Sound Pressure Level (SPL) meter, an integrating Equivalent Sound Level (LEQ) meter, or a peak reading signal level meter calibrated to digital full-scale. the labels above and below the large numeric value in the center of the display function as menus that enable you to select the input channel driving the display and the type of measurement you wish to perform.

 

To configure these functions click anywhere in the center portion of the meter or select SPL/LEQ from the Options menu to open the Sound Level Options dialog. Here you can select weighting curves and integration times independently for both SPL and LEQ measurements, specify a text file for logging, and access the calibration dialog to calibrate your input device(s) and microphone(s) for SPL/LEQ measurement.

 

leq_meter

 

When operating as an LEQ meter, small numbers on the left indicate the maximum and minimum SPL readings encountered during the integration time period. below the Min and Max SPL readings is a small round button that glows red until the LEQ buffer is fully populated for the specified integration time period, then changes to green. Clicking this button with your mouse will flush the LEQ buffer and force it to repopulate.
