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.
