New updated - "Sound Level Analyzer PRO” ver 3.0


"Sound Level Analyzer PRO" has been updated to ver 3.0.

"Sound Level Analyzer PRO" is a new integrated sound measurement app with sound level measurement and powerful sound analysis tools.

It is a professional-grade sound level measurement app further evolved from "Sound Level Analyzer".

It can display automatically the instantaneous sound level such as environmental noise, specific sound sources, live sounds in real-time.

In addition, this app has advanced sound analysis functions that can perform "Power Spectrum Analyzer", "Time Course graph", and "Statistical Analysis (Histogram, Percentile Level)".

It can be used to analyze characteristics and trends of occurrence for the noise/sound source.

In the latest version, the FFT analysis display has been changed to make it easier to see the frequency bands with high audibility (100Hz-3kHz, 3kHz-6kHz). Also, it has been added a process to prevent erroneous operation during measurement.

# Examples of the sound level vs. the environmental noise.
 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 standard noise measurement range is 30 to 130 dBA, and the measured value (Leq) is about 30 dBA in a quiet room. Noise levels are never measured at 0dBA even in very quiet environments.
