Noise Control (EAC1051)

Undergraduate course at UFSM lectured by Dr. Paulo Mareze.

Sound absorption and 1 degree of freedom vibration modeling

• Adds helmholtz_layer to the TMM package;
• Transmissibility plots for vibration control analysis.

Piston on an infinite baffle simulator

• Simulates a radial piston sound source using a discrete approximation of the Rayleigh integral.
• SPL per frequency, SPL along axis, directivity and contour plots.
• Comparisons with the analytical models (exact and far field approximation) seen on Kinsler's Fundamentals of Acoustics (4th ed), chapter 7.

Transformer noise calculator

• Calculates the sound power level and sound pressure level for the noise of an industrial transformer humming indoors.
• Equations taken from Barron's Industrial Noise Control and Acoustics (1st ed).

Installation

The uv package manager is the recommended way to use this project. Clone the repository, cd into the project folder and run uv sync. This will install all dependencies. Afterwards, you can run uv run --with jupyter jupyter lab to start the JupyterLab environment and explore the notebooks.
