What's New in Noise Level Meter
1.5
September 15, 2026
Measure equivalent sound level with LAeq, switch Fast or Slow response, and choose which microphone you use — more control over every SPL reading. New • LAeq measurement: track equivalent continuous sound level so you can see average exposure over time, not just the live decibel reading. • Fast/Slow response: switch the meter’s time weighting to match how you measure — Fast for changing noise, Slow for a steadier sound-level readout. • Microphone source: select which mic to use so you can measure with the built-in microphone or an external source when you need a clearer capture.
