Master Thesis - Acoustic near field measurements i Lund

At Bosch, we shape the future by inventing high-quality technologies and services that spark enthusiasm and enrich people’s lives. Our promise to our associates is rock-solid: we grow together, we enjoy our work, and we inspire each other. Join in and feel the difference.

Bosch R&D Center Lund stands for modern development in cutting edge technology in the areas of connectivity, security, mobility solutions and AI. We are growing rapidly and looking for people to join us on our mission to become the Bosch Group’s 1st address for secure connected mobility solutions. We are working on a range of interesting projects, with a particular focus on software development for the automotive industry, electrical bicycles and Internet of Things.

Problem statement.
Many consumer products have buzzers or speakers to provide audible feedback to users. The output is created by audio components and the specific integration into a housing. Therefore the development includes an iterative process of building, testing and comparing possible solutions. Audio test chambers are normally large in size and costly to use. The idea is to achieve meaningful and indicative test results with a compact setup where we focus on making near field audio measurements instead.

Proposed solution.
The preliminary structure of the project is made up of three parts:
a.    Study: An initial phase investigating standard solutions for audio measurements with different equipment and effectiveness with the purpose of making near field tests. Study literature with state-of-art solutions and define important sound parameters to be measured.
b.    Design: A design and implementation phase where a test setup and process for acoustic near field measurements is proposed. Programming will be done in Matlab.
c.    Evaluation: An evaluation phase includes acoustic near field measurements in comparison standard solutions and describe the correlation. Potentially support this with simulations.

Scope of master thesis project.
Two students completing 30 credits each (20 weeks) onsite at the Lund office.

Your profile.
In order to be successful in the project with think you are:
•    Familiar with Matlab.
•    A student in Engineering Physics, Electrical Engineering or similar, with a strong interest in acoustics, measurement techniques and signal processing.
•    Self-driven, able to challenge yourself, and gain the experience needed to move the project forward. You need to be “hands-on” as the goal is to finalize a measurement setup.

Supervisors.
LTH: TBD
Bosch: Gunnar Klinghult at RBSN/ESW16

Only applications from students at a Swedish University are accepted.

Your future job location offers you:

Flexible work time options, benefits and services, medical services, employee discounts, various sports and health opportunities, catering facilities, collective agreement, wellness contribution, access to local public transport, and room for creativity.
Diversity is our strength! At Bosch we look at diversity in gender, generation, nationalities and culture as our advantage. We believe mixed teams to be more successful because they utilize the potential offered by different perspectives and solution strategies. We therefore promote mixed teams at all levels and draw on the entire talent pool.
