Take your external calibrator and turn it towards the microphone on your unit. Taking your calibrator and putting it right over your microphone is very effective as well. Then, you simply turn on your calibrator and let it works its magic. This will calibrate your sound level meter.
How do I calibrate my microphone?
The calibration is performed by exposing the reference microphone to the sound field, taking a measurement, and then using the test microphone to measure the (ideally) identical field.
What is a calibration file?
The calibration file contains information about the precise position of the right and left cameras and their optical characteristics. This file is key in the depth estimation process and guarantees its quality.
Do dB meters need to be calibrated?
Calibration of your sound level meter by its manufacturer manufacturer is something I recommended annually. Some regulations (like the 2005 Control of Noise at Work Regulations) state that a sound level meter should be returned every two years and the acoustic calibrator every year.
