Description
"Sound Level Analyzer Lite" is a sound level meter app for iPhone. Available in variety of applications as the neighboring environmental noise measurement, audio system check, vehicle interior noise check, sound check of live events, and more. This app can easily set the frequency weighting characteristic and the time weighting characteristic necessary for sound level meter, and appropriate sound level measurement is possible. It also has the calibration function to adjust the microphone level for each device. Features: - Sound level measurement (dB): Leq (equivalent noise level), Lmin (minimum value), Lmax (maximum value), Lavg (time average equivalent noise level) - Frequency weighting correction characteristics : A (for noise level meter), C (for sound level measurement), Z (no correction) - Time weighting characteristics : Fast = 0.125 sec, Slow = 1.0 sec - Calibration function: level correction value setting, -20 to +20dB - Measurement time: 20 sec Applications: - Live Sound - Environmental noise measurement - Installation of audio equipment - Tuning of audio equipment - Architectural acoustics - Broadcast - Device management Example of the noise level situation: - 130dB : Engine sound of Airplane - 110dB : Horn of Car - 100dB : Noise of passing train - 90dB : In loud factory - 80dB : In the train, Vacuum cleaner - 70dB : Noisy office, Noisy street - 60dB : Quiet Car, Normal conversation - 50dB : Quiet office - 40dB : In the library, Quiet residential area - 30dB : Outskirts of midnight, Whisper - 20dB : Sounds of rubbing leaves Note: At the time of the first access to Microphone and Photos after installing the app, you will be asked authorization to access them by the iOS system. If you have not enabled this setting, the app can not access them by privacy restrictions of the iOS system. Please enable the access permission on the iOS setting, "Settings > Privacy > Photos or Microphone". The standard noise measurement range is 30-130 dBA, and even in a quiet room, the measured value is approximately 30 dBA. In any silent environment, it will not be measured with very low noise levels, such as 0 dBA. The WHO has proven direct links between noise and health risks; tinnitus, sleep disturbance, stress, cognitive impairment, heart diseases and annoyance in general. Please check your environmental noise for your wellness. Please visit our iOS App Support page for more information on this app.
Auto rotate gone, up 4 steps back

Ability to auto rotate gone. To see the screen and point the mic is not possible any longer. UI looks much worse.
Crashes on iPhone X

Crashes back to iOS when starting to listen on iPhone X Deleted and reloaded app, still crashes That’s all I have to say, this used to be a great app.
Does not record sound actively

I tried this out in a very noisy environment and it did not register any sound. There are no instructions or settings that I could find. I assume it does not work with my iphone 5s.

I tried to use this app and it was impossible because of the ads covering up part of the screen. I deleted it.
well-designed and accurate

I'm an acoustical consultant, and tried out a few free sound level meter apps. This was the best I tried because it offers A, C and Flat weightings, calibration, fast and slow response, min, average, max and Leq levels. Nice job on this useful app.

Seems to do what it should easily and quickly.
Decibel Recorder

Excellent app. Easy to use and it gave uniform dBA readings when compared to other decibel recorders.
Great free app

The DEP was just here in my apartment in NYC measuring sound with a $3000 sound meter. I tested three apps concurrently and this one was the most accurate.
Worthless to me

I play most of my music off my iPhone. I cannot run this application at the same time that I'm play my MP3s! What's with that? How do I play my MP3s and know the decibel level? You can't with this application.
Great fun
