• This example shows how to measure and monitor the sound level by continuous measurement function of LA-4441.A For example, measure the maximum value and time-average sound level (equivalent continuous sound level, L_eq) continuously for an hour. This continuous measurement function allows long time measurement at fixed point outdoors. The LA-4441A Class1 integrating sound level meter enables the more accurate measurement.
• The measurement data is stored automatically in the internal memory. The stored measurement data can be transferred to the PC via USB or RS-232C interface.
