NoiSee

For what I was needing this sound meter app got the job done. This app renders a lot of data that I did not quite understand but that is ok. As another reviewer stated, this app will fail upon startup at times but that is easily overcome. 5 stars!

Seems like a nice sound level app. It hangs and locks up when opening. Only way to get it to run is to reboot it by swiping it closed and restarting it. It works fine till I close it and try and run it again at which time it is locked up

I am a regular user of the NIOSH sound level meter developed by this company. Today I found the NOiSee dB meter and from the description, it sounded like it fit what I was looking for- mostly over the NIOSH app is the ability to see graphed results. First the good- the best part about this app is the time to 100% dose. Helpful for workplace sound surveys. The bad- for US/ OSHA, there are too many unnecessary features. The resolution in the graphs are way too big. 10 seconds? Won’t show echos or secondary pulses. The biggest negative is you can’t save or send a survey. That costs extra, not explained in the description. $0.99 won’t break the bank but the NIOSH dB meter has better functionality for free, however it does only measure to OSHA or NIOSH standards. I did use a QC-10 calibrator with a Dayton Audio iMM-6 external mic and had to correct -8.5. With the external mic after calibration, the readings are 2dB higher than my 3M Edge 4 dosimeter.
