Online Decibel Meter


🎯 What is a Decibel Meter?

A decibel meter (also known as a sound level meter) is a device or tool that measures the intensity of sound in decibels (dB). The decibel scale is logarithmic, meaning every 10 dB increase represents a tenfold increase in sound intensity. For example:

  • 30 dB – Whisper

  • 50 dB – Normal conversation

  • 70 dB – Busy traffic

  • 100+ dB – Loud concert or machinery

Prolonged exposure to high dB levels can cause hearing damage, so monitoring sound levels is essential in many environments.

🌐 Why Use an Online Decibel Meter?

An online decibel meter uses your device’s microphone to detect sound levels in real time. Here’s why it's so handy:

  • ✅ No installation needed – Works directly in your browser

  • 📱 Mobile and desktop friendly

  • 🆓 Completely free

  • 🎙️ Live microphone input for accurate readings

  • 🔧 Great for classrooms, meetings, home studios, and more

🛠️ How Does It Work?

Using the latest Web Audio API, the tool accesses your microphone (with permission), processes the incoming sound data, and displays the real-time decibel level. It calculates both the instant dB and can show a peak or average level, depending on how it's configured.

Note: Accuracy depends on your device’s microphone and background noise. While it’s great for general use, it's not a replacement for professional equipment in critical situations.

💡 Use Cases
