– Primary Test: Connect the Sound Level Sensor to an interface. The data-collection software (LabQuest App, Logger Pro 3, or Logger Lite) will identify the sensor and begin a live readout of the sound level. Normal classroom sound levels should be 60-70 dB; a quiet office should read around 55 dB.
– Minimum software version: Logger Pro 3.10, Logger Lite 1.9, or LabQuest App 2.6 (original LabQuest version 1.7.4)
What is the difference between the Sound Level Sensor and the Sound Level Meter?
What advantages does a Vernier sound level sensor have over a smartphone sound level app?
What is the difference between "A weighting" and "C weighting"?
Why doesn't my sound level meter read below 40 dB?
Range: 55 – 110 dB
Accuracy: +/- 3 dB
Resolution: 0.1 dB
Frequency Range: 30 – 10,000 Hz
Note: The Sound Level Sensor will never need to be calibrated. Each sensor is carefully calibrated before it ships, and this unique calibration is stored on a smart chip in the sensor.
Note: There is no method to perform a calibration of this sensor in most of our software programs; however, there is no need to do so. Logger Pro does allow for an approximate calibration, but the results would likely be less accurate than the custom factory calibration.
