## What is Decibel Alarm+ dB Noise Alert?

Set custom noise threshold alerts and get notified when ambient sound levels exceed your limits. Decibel Alarm+ continuously monitors environmental noise through your phone's microphone and triggers alarms when decibel levels cross your preset boundaries.

Perfect for monitoring noise levels in offices, classrooms, nurseries, or any environment where sound control matters. Set multiple threshold levels with different alarm types — visual, haptic, or audio notifications.

The real-time dB meter displays current, average, and peak noise levels with a clean gauge interface. Review noise history logs to identify patterns and troublesome time periods throughout the day.

Ideal for noise-sensitive environments, workplace safety compliance, baby monitoring, or protecting your hearing in loud venues. Runs reliably in the background with minimal battery impact.
