ESP32 Active Noise Cancellation Kit
Build a Portable Active Noise Cancellation System with ESP32: The Noise Pollution Logger Pro Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Urban noise is everywhere-but what if you could cancel it with a device you built yourself? This kit turns a pair of INMP441 MEMS microphones and an ESP32 into a wearable active noise cancellation system. You'll capture ambient sound, compute an anti-phase signal in real time, and mix it into the audio you hear through a headphone cup. It's a crash course in I2S audio, embedded DSP, and battery-powered design, all wrapped into a single project that's equally at home in a college lab or a Smart India Hackathon build.
What You'll Build
A self-contained, battery-operated ANC headphone module that actively reduces ambient noise. Two microphones feed the ESP32, which runs phase-inversion code and outputs a cancelling signal through a DAC and amplifier. The build includes wired ear cups, LiPo power management, and a prototype PCB-giving you a functional wearable that demonstrates the physics of destructive interference in sound.
What You'll Learn
- Integrate I2S digital MEMS microphones and configure ESP32 for stereo audio capture
- Implement real-time anti-phase generation and mixing on a microcontroller
- Drive an MCP4728 DAC and PAM8403 amplifier for clean analog output
- Assemble a safe LiPo charging circuit using the TP4056 module and solder it onto a prototype board

Who This Kit Is For
Final-year B.Tech ECE/EEE students who need a challenging DSP project, Smart India Hackathon teams racing to build an environmental monitor, and IIT/NIT/VIT/BITS learners hungry for practical audio engineering. If you're comfortable writing Arduino or ESP-IDF code and can solder a prototype board, this kit turns theory into a wearable demo in a single day.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to open the AI companion, which was trained on the exact Noise Pollution Logger Pro project. It can walk you through code, wiring, and signal verification. If you still need help, message the same assistant on WhatsApp.
Can I adapt this project to log noise pollution data?
Yes-with the dual microphone capture working, you can extend the ESP32 firmware to send decibel readings over Wi-Fi or log them to an SD card. The AI companion includes starter guidance for that extension.
Is this suitable for a B.Tech final-year project?
Absolutely. The kit provides a complete hardware platform, and the accompanying project documentation covers noise cancellation theory, DSP implementation, and practical results-enough for a thorough project report.
What if a component is faulty upon arrival?
We test all parts as a system before shipping. If anything still arrives defective, contact us within 7 days and we'll send a free replacement immediately.
