I liked it because it gives you a word scale of what every 10 DB compares to for those not familiar with the scale. This with Bosch app that measures DB by frequency in its calibration window helped me isolate a noisy CNC router at home.
More accurate than other noise apps. Also, I wanted a decibel app to go higher than 120, which is what most of the other apps on offer stop at. This one's limit is 140
I'm using it in the hospitality environment. This is a great tool. Amazingly helpful and seems accurately reacting to noises and noise level variations. I would love to be able to screen capture the graphs.
Great app..👍 Very usefull especially when I played electric guitar.. so I could notice if its sound is too loud.
As far as I can tell it is accurate enough to do a rough survey of a noisy area. Not sure if you can adjust.
Other SPL Tools I have used have more features. And they are free, also.
