What were you using for a meter to obtain these readings? What Weighting scale?

A cell phone app is the next best thing to worthless. A professional meter that is calibrated on site with a calibrator, just prior to taking the readings, is the only accurate way to take a meaningful measurement. In my work, I take acoustic sound level measurements on a regular basis to evaluate the effect of professional sound systems in residential neighborhoods. Neighbors seem to all have $20.00 amazon meters or cell phone apps which vary widely and can easily be manipulated to read what suits ones purpose either high or low.

I"m not trying to give you a hard time but simply to bring up the fact that an arbitrary reading has little meaning.
