Noise Monitoring System

The aim of this project is to provide an overview of sound level meters and their components, including the importance of using a condenser microphone for accurate measurements. It also highlights the limitations of sound level meters in measuring human-perceived loudness and the need for loudness meters.

Overview

Sound level meters are essential tools for measuring sound levels in decibels (dB). They consist of several key components, including a microphone, an amplifier, and a display. A condenser microphone is often used in these devices for its accuracy and sensitivity in capturing sound levels. However, standard sound level meters may not always account for human perception of loudness, which is why loudness meters are also important in some applications.

Project Implementation

In this project, we introduce a sound level meter using the ESP8266 microcontroller and a sound sensor. This setup allows for monitoring sound levels in dB, and the data can be uploaded to a Thingspeak server for further analysis.

The components of this system work together as follows:

• ESP8266 Microcontroller: Handles data processing and communication.
• Sound Sensor: Measures sound levels and converts them into electrical signals.
• Thingspeak Server: Receives and stores the data for analysis and visualization.

Importance of Measuring Sound Levels

Measuring sound levels is crucial for various applications, including noise pollution monitoring, environmental assessments, and occupational safety. By using a low-cost sound level meter with readily available components, you can gain insights into sound levels in different environments and ensure compliance with noise regulations.
