With ongoing construction that we see in Singapore, lots of noise escapes the construction site, into the surrounding neighbourhood. While actions for noise control have been taken, through the use of passive noise control techniques, a low-cost Active Noise Control (ANC) system may seek to bring an addition to lowering the noise that leaks out from the construction sites. This project’s focus is on facilitating seamless device-to-device communication between the Raspberry Pi and ESP32 microcontroller, as users engage with the Active Noise Cancellation (ANC) system. This is done via a webpage hosted by the Raspberry Pi, where it has to swiftly transmit its data wirelessly to the ESP32 modules, which will then relay information to the STM32 microcontroller that will execute the ANC algorithm.
