Sound Meter: dB Level Reader

Sound Meter turns your phone microphone into a quick ambient noise reader — point it at any environment and see the decibel level instantly on a color-coded gauge. Readings are indicative only — this is not a calibrated SPL or medical instrument.

KEY FEATURES:
• Live dB readout — real-time decibel level from your phone microphone
• Color-coded gauge — four zones (Quiet, Moderate, Loud, Dangerous) at a glance
• MIN, AVG, and MAX session stats — track the range across any environment
• Real-world reference — see what each level sounds like (whisper, vacuum, concert, and more)
• On-device audio — mic input is processed locally and never recorded or uploaded
• Simple and lightweight — open, grant mic access once, and start measuring instantly

PERFECT FOR:
• Checking how quiet a bedroom or home office really is before working or sleeping
• Gauging how loud a restaurant, gym, or busy street is before you sit down
• Comparing appliance noise (fans, HVAC, machinery) to familiar everyday references
• Getting a quick read on any space without carrying specialist equipment

Readings are indicative only — Sound Meter is not a calibrated SPL instrument and should not be used for OSHA, medical, or hearing-protection decisions.
