Does anyone uses decibel meter app on your smart phone to measure the noise level of your airgun here? does anyone has one to compare it to the real decibel meter.

I use this APP called sound meter. Had the highest ratings for being free. Not sure how accurate it is. Being that well everybody phones may be different. I probably got pocket lint, grease or other stuff stuck in the mic.

But wouldn't mind if someone could compare a app to a proper tester.

Accuray is not that critical if you are just interested in differences . I have an old RS db meter the analog version . They can be found reasonably used . They were closely calibrated to A and C weighting They are calibraitible by the user if you can find a standard. Get one of those if you need to compare to other sourced data.

I bought a decibel meter from Horizon Hobbies. Of course, I let it go with my airplane stuff when I dropped that sport.

Knowing that a good class 2 soundmeter is in the 250$ range I guess you get what you pay for at 30$!! I would recommend any good free app will do a better job.
Read this. https://blogs.cdc.gov/niosh-science-blo ... ound-apps/
Scroll down to the June 2018 update. Good apps have come within 1db of “real” soundmeter readings.

I guess you can make your decisions . Using a $930 Iphone 7 to do what an economy meter can do without tying up your phone does not seem too logical to me . Just my humble opinion but I do like to collect measuring instruments that I seldom use . I have used my analog Rat Shack spl meter to set up some very expensive commercial equipment for both some very public and private owners residences and venues . The skill and experience of the operator can play a significant value in the out come of the adventure . Like I said just my opinion and not unsolicited .As I stated in my first post the absolute value is probably not as important as the difference in the values which I suspect is the object of the endeavour .
