NoiseLevelCalcAssistant is an utility for measuring, visualizing, and understanding ambient sound levels. Using the device microphone, it computes RMS-based metrics to estimate perceived loudness over time, while a smooth waveform and live indicators help you see spikes and trends at a glance. You can start quick real-time monitoring, review recent readings in a tidy list, and drill into details such as minimum, maximum, and running averages to spot patterns. A playful comic-style interface keeps the experience friendly without sacrificing clarity. Helpful tips, lightweight onboarding, and an About screen round out the app, making it a handy companion for classrooms, studios, offices, or everyday noise awareness.
