Yaryhin V. Noise meter

This diploma project consists of 63 pages, 23 illustrations, 30 formulas, 21 literary sources. Key words: ultrasonic control, noise meter

In the diploma project, the study of the principles of operation of various  types of devices for measuring noise. Structural and functional diagrams are made. A schematic diagram and printed circuit board based on shredders were developed. On the basis of the performed calculations an experimental installation was developed.
As a result of the study, a type of instrument was used to measure noise, or rather a noise meter.

 

The purpose of the work is to study existing instruments for measuring noise and selecting a specific type. Its development and drawing up of documentation for it. The object of the study is the process of noise formation with ultrasound non-destructive control. Subject of research - devices for measuring noise. Scientific novelty - The device is designed so that the overall error of the noise meter is very small
