🌐 NoiseLevel Analyzer

NoiseLevel Analyzer is a web-based tool that measures and visualizes environmental sound levels in real time using your device’s microphone.
It helps users analyze ambient noise, visualize decibel intensity, and assess sound pollution interactively.

📸 Features

  • 🎧 Real-Time Sound Monitoring – Uses Web Audio API to capture and analyze microphone input
  • 📊 Dynamic Decibel Meter – Displays live dB levels with smooth animations
  • 🧠 Noise Classification – Categorizes sound intensity (Quiet, Moderate, Loud, Dangerous)
  • 📈 Data Visualization – Plots sound intensity over time using Chart.js
  • 💾 Offline Support – Works offline with cached resources
  • 📱 Responsive Design – Optimized for both desktop and mobile

🧠 How It Works

  1. The app accesses your microphone using the Web Audio API.
  2. It captures audio amplitude and converts it into decibel levels (dB).
  3. The live noise level is displayed with color-coded feedback.
  4. Data is visualized in a real-time graph for trend analysis.
  5. Optionally logs sound data for export or long-term study.

🛠️ Tech Stack

Layer Technology
Frontend HTML5, CSS3, JavaScript (Vanilla or React)

🚀 Getting Started

1️⃣ Clone the Repository

git clone https://github.com/yourusername/noiselevel-analyzer.git
cd noiselevel-analyzer
2️⃣ Run Locally
Open index.html in your browser
OR use a local server:

bash
Copy code
npx live-server
3️⃣ Allow Microphone Access
Grant microphone permission when prompted to start noise detection.

📊 Example Output
Range	Noise Level	Indicator
0–40 dB	Quiet	🟢
41–70 dB	Moderate	🟡
71+ dB	Loud	🔴

The app also provides a real-time graph of sound intensity over time.

💡 Use Cases
Measuring environmental noise around you

Testing sound insulation effectiveness

Educational use for sound and wave experiments

IoT and Smart City noise tracking dashboards

🧩 Future Enhancements
📈 Historical data logging and export

🧠 AI-based sound classification (traffic, music, speech)

📱 PWA support for Android

🌍 Global community noise map integration
