## What is Sound Decibel Meter+?

Measure sound levels instantly with a smart decibel meter. Understand noise levels, track dB readings, and protect your hearing.

Decibel Meter turns your phone into a smart noise analyzer that goes beyond raw numbers — giving you instant context, safety insights, and a clear picture of your sound environment.

Use Decibel Meter as a sound level meter, noise meter, or dB meter to instantly measure environmental noise around you.

WHY DECIBEL METER?
Most sound meter apps show you a number. Decibel Meter shows you what that number actually means — whether it's safe, how long you can stay, and what everyday sound it compares to.

REAL-TIME MEASUREMENT
• Live dB readings with smooth waveform visualization and real-time sound level measurement
• Auto-start — opens and measures immediately
• Min, Avg, and Max tracking per session
• A-weighted (dBA) measurement for accurate readings

NOISE INTERPRETATION
Every sound level reading is paired with real-world context:
• 45 dB — Quiet home (safe)
• 72 dB — Busy restaurant (safe for several hours)
• 88 dB — Lawnmower (limit to ~2 hours)
• 100 dB — Loud concert (hearing damage risk)

HEARING SAFETY INSIGHTS
Understand exposure limits based on health standards. Know when noise is harmful and how long you can safely remain in your environment.

SESSION HISTORY
Save and review past measurements. Rename sessions, swipe to manage, and track noise exposure over time.

SHARE YOUR READINGS
Generate clean share cards showing your measurement, interpretation, and safety info — perfect for social media or reports.
