CF-5200 Frequently Asked Questions

If the surrounding noise (background noise) is louder than the target sound, accurate measurements cannot be taken.

Please block the background noise so that the difference between the background noise and the target sound is 10 dB or more.

After accurate measurement, you can subtract the stored data (background noise) (background noise correction) using the "-" function in the arithmetic operations.

To simply take the difference, you use the arithmetic operation "/".
