"Sound Level Analyzer PRO" has been updated to version 7.0 today!"Sound Level Analyzer PRO" is a new integrated sound measurement app with sound level meter and powerful sound analysis tools.
It is a professional-grade sound level measurement app further evolved from the standard SLM app,
"Sound Level Analyzer".
Available in a variety of applications, such as the neighboring environmental noise measurement, audio system check, vehicle interior noise check, sound check of live events, and more.
With its advanced sound analysis capabilities, you can perform real-time frequency spectrum analysis, time-varying level measurement, and in-depth sound level statistical analysis. It can be used for multifaceted analysis of complex sound characteristics and trends in frequency of occurrence of any sound source.
The latest version supports iOS 18.2 and has a renewed UI design.
* Sound Level Measurement

* Power Spectrum (1/3 octave-band frequency analysis / FFT)

* Maximum Level Detection (detects the maximum level within the measurement time and displays the frequency spectrum at that point)

* Time Course Graph (graphically displays measurement results for up to 8 hours)

* Sound Level Statistical Analysis (histogram, time rate noise level)

* Examples of sound sources and noise levels
130 dB: Engine sound of Airplane
110 dB: Horn of Car
100 dB: Noise of passing train
90 dB: In loud factory
80 dB: In the train, Vacuum cleaner
70 dB: Noisy office, Noisy street
60 dB: Quiet Car, Normal conversation
50 dB: Quiet office
40 dB: In the library, Quiet residential area
30 dB: Outskirts of midnight, Whisper
20 dB: Sounds of rubbing leaves
Note: The standard noise measurement range is 30-130 dBA, and the measured value (Leq) is about 30 dBA in a quiet room of the household. Due to the presence of background noise, noise levels are never measured at 0dBA even in very quiet environments. In a typical anechoic room, the noise level is around 5-15 dBA.
The World Health Organization (WHO) has published noise level indicators related to health risks caused by noise, which are listed below as a reference for noise management.
* Noise level and permissible exposure time
100dB: only a few minutes/day (weekly limit of 20 minutes)
95 dB: 10 minutes/day (weekly limit 1 hour 15 minutes)
90 dB: 30 minutes/day (weekly limit 4 hours)
85 dB: 1 hour 45 minutes/day (weekly limit 12.5 hours)
80 dB: 5.5 hours/day (weekly limit 40 hours)
In general, the quality of life begins to be affected at levels above 60 dB, and the risk of health problems increases at levels above 80 dB. Prolonged exposure to high levels of noise can cause temporary hearing loss.
