NoiseLogger

NoiseLogger is a compact sound measurement and logging app that records ambient noise levels, stores readings with timestamps, and produces simple charts for analysis. NoiseLogger captures decibel measurements in real time and saves sessions as exportable CSV files.

How it works

NoiseLogger samples sound through the device microphone and displays current decibel (dB) values alongside a running log. You can set threshold alerts, choose sampling intervals, and review recorded sessions on a simple timeline chart.

Key features

• Real-time dB meter showing approximate sound levels
• Timestamped logging of measurements for later review
• Export to CSV for analysis on a computer
• Threshold alerts with optional notifications
• Configurable sampling intervals and optional background logging
• Local data storage with explicit microphone permission

Data remains on your device unless exported. NoiseLogger is intended for general noise awareness and basic analysis, not for certified acoustic measurements.
