Design And Construction Of A Noise Meter / Sound Meter

The design and construction of a noise meter, also known as a sound meter or sound level meter, involves the integration of various components to accurately measure sound pressure levels in decibels (dB). Key components include a microphone to capture sound waves, a preamplifier to boost the weak signal from the microphone, an analog-to-digital converter (ADC) to digitize the analog signal, and a microcontroller or digital signal processor (DSP) to process the digital data. Additionally, the device requires a display interface to visualize the measured sound levels and user interface elements such as buttons or a touchscreen for user interaction. The construction phase involves assembling these components into a compact and durable enclosure, ensuring proper calibration for accurate measurements, and implementing features such as data logging and adjustable settings for versatility. Through careful design and construction, the noise meter can serve as a reliable tool for various applications, including environmental monitoring, industrial safety compliance, and noise pollution assessment, enhancing efficiency and promoting safer environments.

ABSTRACT

This work is on a noise or sound meter. This device is used to measure the level of noise. With the portable noise meter you can carry out measurements quickly to gain control of a situation or to set the sound meter to take timed measurements. The noise meter is important for all industries, especially by using it as a mobile noise meter which is able to assess office stress levels or street noise levels. Often problems arise from noisy neighbours or if bars and restaurants are in residential areas and produce noise levels after 10 pm in excess of what local laws permit. A noise meter / sound meter will help here.
