Decibel Meter is full of features sound level meter with exclusive accuracy of measurements and integrated spectrum analyzer. Calibrated with professional dB meter.
The world is a noisy place: cars, power tools, crowds, machinery, and other common sources produce amounts of noise that can, with continued exposure, lead to permanent hearing loss. Sound level meters are useful for anyone who wants to avoid exposing their ears to harmful noise levels, but who wants to spend hundreds of dollars on one?
dB Meter is free app which provides professional-quality measurement results, calibrated using an actual Nor140 high-precision decibel meter. With dB Meter, you can measure ambient noise levels, save your measurements and their locations, and share your measurements with others. dB Meter couples utility with stylish design and a polished user experience: a powerful tool in a sleek package, and at a tiny fraction of the cost of professional sound level meters.
(Please note that dB Meter soundmeter app is not a replacement for professional devices and should be used for personal purposes only.)

DB Chart
150-160 dB = Eardrum rupture
140 decibel = Aircraft carrier deck.
130 dB = Jet take-off (100 meters), gun blast at close range.
120 dB= Human pain threshold, loud rock concert.
110 decibel = Serious hearing damage if sustained for more than 1 hour.
100 dB = Serious hearing damage if sustained for more than 8 hours.
90 decibel = Likely hearing damage if sustained for more than 8 hours.
80 decibel = Potential but unlikely hearing damage if sustained for more than 8 hours.
70 dB = Just annoying, but probably safe.
60 dB= Typical conversational volume.
50 dB = A quiet, library conversation.
40 decibel = A whisper.
30 dB= Barely audible sound.
20 decibel= Threshold of human hearing.
Latest reviews of dB Meter & Spectrum Analyzer app for iPhone and iPad
The db-c filter fives gives me a MUCH higher value than the db-z filter. This should never be the case because the db-z filter is strictly flatter than the db-c filter. The db-c filter attenuates the bass more. So why is it giving me a significantly larger reading?
Very useful where accurate sound metering is needed.
(See update) (original review--5 stars). The calibration feature is uncommon among sound level apps–good feature. Clean design. The addition of a higher contrast screen toggle would be awesome. Another app that makes our phones that much more useful. (Update--3 stars). I want to like this app. Developer states for personal use. Suspect most higher ratings from those who havent confirmed operation of app. I have since checked against Quest metering and calibration equipment. Theres no easy way to calibrate this app without crashing. Tried everything: reset phone, shutdown/restarted phone, try calibrating again and again (5s).... Wont get into specific readings and numbers. Bottom line: not accurate as I hoped it would be but find it roughly acceptable for gross measurements only--quiet, noisy, loud enough to probably need hearing protection--dbA only. DbB, dbC not even close. To be fair lets consider that the app resides on a "phone". Be careful. 3 stars down from 5. (Report 3, Jan. 24, 4 stars) Update released January 24… Good news, at least for me, no more crashing during calibration of DbA. But, DbA calibration tricky at higher noise levels. Measures accurately at mid levels. (See #value delta of cal. screen vs. live measure screen). Developer: thank you for conscientious updates. On your way to "best-of" app Users: quick note – remember to hold your phone upside down, microphone in the air, not in the palm of your hand blocking microphone. Developer--possible tweak for future updates??-flip screen 180 degrees feature!!
Very handy on measuring db in surrounding area . Great to use at sports events to see how loud it is, or just around the house. It is great for the price and is pretty accurate
This app is amazing, a must try app. Easy to use interface great layout!
