Thesis proposal – Methodology to analyse sound in a noisy environment

Title:

Methodology to analyse sound in a noisy environment

Description of the thesis proposal:

In production of electronic products, it is sometimes desired to measure and analyse different types of sound and vibrations from a test object. A challenge with this type of measurements is to filter the wanted sound from the surrounding noise in a factory environment.

The thesis should consist of analysing different test methods and equipment to detect and filter out the sound from the surrounding noise as a measurable signal. It should be possible to compare the wanted signal with stated acceptance criteria.

For example, the thesis work could include:

• Signal amplifying and filtering by designing custom hardware.
• Signal amplifying and filtering by using standard computer hardware.
• Signal filtering using software.
• FFT-analysis.

The main goal of this thesis is to compare some different test methods and determine the reliability and accuracy of these. The project covers literature studies, hardware development and/or software development.

We seek one to two students for this thesis. Depending on the applicant’s background and interests, we are flexible in the scope of the thesis project.

For a successful thesis work, we believe that the applicants should:

• Experience in electronics and hardware.
• Interest/knowledge of Signal Processing.
• Interest/knowledge in programming.

Application:

We look forward to receiving your resume, and preferably, a personal letter in which you explain why you want to write your thesis with Syntronic.

We screen and evaluate applications on an ongoing basis.
