Hi everyone, i'm looking for finding the db value with a grove sound sensor with the value of analog read

```
float volt = sensorValue * (5.0 / 1023.0);
```

is for finding the value of analog read in volt

Use this formula to convert voltages to decibels: 20 * Log (Vout / Vin) = dB

I need to know if http://www.seeedstudio.com/wiki/Grove_-_Sound_Sensor Can give me the result in DB by working out with those formula

thank you.
