This project aims to develop an affordable and efficient sound level meter using an Arduino microcontroller. The primary objective is to measure sound pressure levels in decibels (dB) and display the ...

Fig. 1: Circuit diagram of the noise level monitor. When sound is detected by the microphone in the sound sensor module, corresponding voltage and sound levels are displayed in dB on LCD1. Sound ...

Lucía Garbo has created an Arduino powered noise pollution monitor, powered by an Arduino Mega micro-controller and housed in a 3D printed case. Other components include a SparkFun Sound Detector ...

It is, of course, possible to realize such a circuit entirely using only discrete components, but in this article we will show you how you could build one using an Arduino and a multipurpose shield.

The sound level meter, however, does not take into account the predominant frequency region of the noise, or other factors which may cause annoyance. Compare: COMMUNITY NOISE EQUIVALENT LEVEL , ...

Like Arduino? You can build a Sound-Level Protector using an Uno, an Elektor-developed multipurpose shield, ... Circuit: Multifunction Frequency Meter. Photovoltaic Basics (Part 2): Integrating the ...
