Description
iSPL PRO turns your iPhone, iPad, or iPod touch into a smart Sound Pressure Level (SPL) meter using the built-in microphone. Measure surrounding noise quickly and easily with both digital and analog display modes.
• Real-time sound level measurement
• Current, Average, Minimum, and Maximum values
• A, B, C, and D frequency weighting filters
• Linear (unweighted) mode
• Fast or Slow response modes
• High, Normal, or Low time resolution settings
• Start or stop measurements anytime with a single tap
• Calibration adjustment up to ±10 dB for improved accuracy
• Multiple display styles with digital and analog views
• Three graphical sound level visualizations
• Save and send measurement results via email
• Quick reference guide with real-life noise examples (available in unweighted mode)
The app comes pre-calibrated for the typical built-in microphone of supported Apple devices. If readings differ from a traditional SPL meter, you can fine-tune accuracy from the Settings screen.
iSPL PRO provides an estimate of environmental sound levels and is intended for general and entertainment use. It is not designed as a certified professional measurement instrument.
