Master Thesis – Identification and compensation of acoustical environments using the loudspeaker to microphone signal path

The placement of Axis audio products, such as near windows or in room corners, can affect their frequency response and perceived sound quality. This thesis explores how a speaker and its built-in microphone can be used to identify the surrounding acoustic environment. The aim is to investigate whether environment-specific adjustments to individual speakers can improve audio performance.

The assignment

• Develop a method to measure or identify an audio device's acoustic surroundings using its integrated loudspeaker and microphone.
• Compare excitation signals, such as logarithmic sweeps and continuous noise, to assess their suitability for acoustic environment identification.
• Investigate how the measured acoustic characteristics can inform adjustments that improve perceived sound quality.

Who we are looking for

• Currently pursuing a master's degree in a relevant subject, such as computer science, electronics engineering, acoustics engineering, mathematics or physical sciences.
• Interested in audio technology, engineering, signal processing and/or embedded firmware development.
• Enrolled at a Swedish university or university college, either directly or through an exchange programme.

What we offer

• An open, friendly workplace that emphasises collaboration, new ideas and continued development of skills and working methods.
