"Sound Level Analyzer" is the standard sound level measurement app with sound frequency analysis tools. It is available for a wide variety of applications, such as measuring ambient noise in neighborhoods, testing audio systems, checking interior noise in vehicles, checking sound at live events, and much more. "Sound Level Analyzer" has additional analysis features, which are time graph, real-time frequency spectrum analyzer (RTA) and FFT analyzer. It can be used to analyze sound source characteristics. Features: # Measurement and Analysis functions Main (Leq): Sound level measurement (real-time display) - Sound level measurement (dB): Leq (equivalent noise level), Min (minimum value), Max (maximum value), Avg (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 Power Spectrum (P.S.): View of frequency spectrum analysis (real time display) - Spectrum analyzer function: FFT analysis, 1/3-octave band response analysis. - FFT frequency range settings: 100Hz - 20kHz (FFT all) / 100Hz - 3kHz / 3k - 6kHz - Measured value display function in 1/3 oct band response analysis. (OctVal) - Power spectrum display function at the time of occurrence of Max. (Display Max) # Control functions - Calibration: level correction value setting, -20 to +20dB - Measurement timer: 1 minute / 5 minutes / 10 minutes / 15 minutes / 20 minutes / 30 minutes / 1 hours - Snapshot (Snap): Save measurement display with time stamp to Photos. 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: The first time the app accesses the built-in microphone and Photos after installation, the iOS system will ask you for permission to access them. If you have not enabled this setting, the application will not be able to access them due to iOS system privacy restrictions. Please enable the access permission in the iOS setting "Settings > Privacy & Security > Photos or Microphone". Please visit our iOS app support page for more information on this app.
