The sound sensor is theoretically, a better sensor than the loudness sensor as it’s more rich in the amount of data it caries. Unfortunately, the sound sensor is rather an ill-fitted sensor for the
GrovePi as our board is only capable at reading values up to a certain frequency that’s much lower than the frequency at which the sensor is operating.
Thus, we introduced the loudness sensor which has incorporated a low-pass filter and makes it more suitable for our platform.
On the other hand, these 2 sensors can only operate in a certain range of sound levels - 130 decibels is extremely loud and I doubt these 2 can make a distinction.
And if you search for their datasheet, I doubt you’ll see any relevant technical specs about it related to the range of sound levels.
I haven’t done a research on microphones, but I’m pretty sure there are other microphones that can go up to that level of loudness - you could then implement it with a
