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

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.

# Measurement function

Main : Sound level measurement (real time display)

- 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

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 - 8kHz / 8k - 16kHz

- Measured value display function in 1/3 oct band response analysis. (Value)

- Power spectrum display function at the time of occurrence of Lmax. (display Max)

Time Course (T.C.) : View of time-history of the sound level. (graphical representation after measuring completion.)

- Time-domain fluctuation level display function: up to 8 hours linked on a timer.

Statistical Analysis (S.A.) : Statistical analysis of sound level at A-weighting and Fast. (analysis display after measuring completion.)

- Histogram : Displays all detected sound level distribution as a percentage.

- Percentile Level (LN:dB): Display the levels of L05 / L10 / L50 / L90 / L95 on the percentile level graph.

# Control function

- Calibration function : level correction value setting, -20 to +20dB

- Measurement timer function : 1 minute / 5 minutes / 10 minutes / 15 minutes / 20 minutes / 30 minutes / 1 - 8 hours (1 hour unit)

- Snapshot : Save measurement display with time stamp to Photos.

# Examples of usage scenes:

- Measure the noise situation in the workplace.

- Examine the frequency component and time variation of noise target.

- Check the sound level and background noise level during music performance.

- To know the sound volume of snoring at sleep.

- Measure the quiet characteristics of electric products for the judgment of purchase.

- To know the noise level of the car. Also, as a purchase consideration material for automobiles, measure the in-car noise level at the test drive and compare it.

- To know the noise situation in my home. Also, when buying a house, knowing the noise situation of the surrounding environment.
