This article explores the linear relationship between decibel values and voltage output, providing a conversion formula for user convenience.
Relation between dBA Value and Voltage Output
For this product,the decibel value is linear with the output voltage. When the output voltage is 0.6V, the decibel value should be 30dBA. When the output voltage is 2.6V, the decibel value should be 130dBA.
Decibel Value(dBA) = Output Voltage(V) × 50
The calibration is done before leaving the factory, so you don't need to calibrate it.
