Frequently Asked Questions
Everything you need to know about Sound Level Analyzer
What is Sound Level Analyzer?
Sound Level Analyzer is a standard sound level measurement app with advanced sound frequency analysis tools. It measures ambient noise, tests audio systems, and analyzes sound source characteristics using features like Leq, RTA, and FFT.
What types of sound level measurements does the Sound Level Analyzer app provide?
The Sound Level Analyzer app provides Leq (equivalent noise level), Min, Max, and Avg (time average equivalent noise level) measurements in dB. It also offers frequency weighting characteristics (A, C, Z) and time weighting (Fast, Slow).
Does Sound Level Analyzer include a frequency spectrum analyzer?
Yes, Sound Level Analyzer includes a Power Spectrum (P.S.) view with real-time frequency spectrum analysis. It performs FFT analysis and 1/3-octave band response analysis. Users can set FFT frequency ranges from 100Hz to 20kHz.
How does the Sound Level Analyzer app handle microphone and photo access on iOS?
The iOS system asks for permission to access the built-in microphone and Photos on the first use. Users must enable these permissions in iOS Settings under 'Privacy & Security' to ensure the Sound Level Analyzer app functions correctly.
Can users calibrate the Sound Level Analyzer app?
Yes, Sound Level Analyzer allows users to calibrate the measurement by setting a level correction value. This value ranges from -20dB to +20dB, enabling precise adjustments for accurate sound analysis.
What is the purpose of the 'Snap' feature in Sound Level Analyzer?
The 'Snap' feature in Sound Level Analyzer allows users to save the current measurement display with a timestamp to their Photos. This function captures a snapshot of the analysis results for later review.
What are the primary applications of the Sound Level Analyzer app?
Sound Level Analyzer applies to live sound monitoring, environmental noise measurement, audio equipment installation and tuning, architectural acoustics, broadcast, and device management. It serves diverse professional and personal needs.
What frequency weighting characteristics does Sound Level Analyzer offer?
Sound Level Analyzer offers A, C, and Z frequency weighting characteristics. A-weighting is for noise level meters, C-weighting for general sound level measurement, and Z-weighting provides no correction.
Can Sound Level Analyzer display a time graph of sound levels?
Yes, Sound Level Analyzer features a time graph, which is part of its additional analysis capabilities. This graph visually represents sound level changes over time, aiding in the interpretation of fluctuating noise.
