Master Thesis - Loudspeaker Characterization For Public Venues

Axis Communications AB; Lunds kommun; On-site; SEK 167,000 - 246,000; Full time

Job summary

Axis Communications invites a Master Thesis student to explore loudspeaker characterization for public venues. The project covers Spinorama measurements, installation effects, and performance metrics relevant to ceiling, column, and distributed loudspeaker systems.

Candidates should be pursuing a Master in Signal Processing, Acoustics or Engineering Physics, with a strong interest in acoustics and digital signal processing of audio signals.

Qualifications

• Enrolled in a Swedish university for a Master program in a relevant field (signal processing, acoustics or engineering physics).
• Strong interest in acoustics and digital signal processing of audio signals.
• Enthusiasm for applying measurement methods to real-world loudspeaker installations.

Responsibilities

• Review Spinorama and other measurement methods for loudspeakers used in public venues.
• Investigate effects of installation, venue acoustics, and audience coverage on measurements.
• Develop or evaluate curves and metrics describing performance in real applications.
• Measure and/or simulate configurations and compare methods to support acoustic and signal-processing design.

Master Thesis - Loudspeaker Characterization For Public Venues

Job Description

DSP and Acoustic

Category

DSP and Acoustic

Scope

2 students completing 30/60 credits (20/40 weeks) each.

Background

Spinorama measurements describe a loudspeaker’s frequency response and sound radiation across different angles. They are commonly used for cabinet speakers in domestic listening environments, but public indoor and outdoor venues often use other loudspeaker types and installation setups. This thesis will explore how measurement methods can be adapted to evaluate these systems and their performance in real applications.

Goal

The objectives below are suggestions rather than strict requirements. We will decide together which objectives to focus on and whether to adjust them to fit your interests and the direction of the thesis.

• Review existing measurement methods, including Spinorama, and assess their suitability for loudspeakers used in public venues, such as ceiling speakers, column speakers and distributed systems.
• Investigate how installation, venue acoustics, audience coverage, and indoor or outdoor conditions affect measurement results.
• Develop or evaluate curves and metrics that describe application-specific performance, such as frequency-response consistency and coverage across audience areas.
• Measure and/or simulate selected configurations, compare conventional and proposed methods, and recommend approaches to support the acoustic and signal-processing design of future Axis Communications products.

Who are you?

For this Thesis proposal we target students with a strong interest in acoustics and digital signal processing of audio signals. Most likely you are studying a Master Program in Signal Processing, Acoustics or Engineering Physics.

OK, I am interested! What do I do now?

• Applications are accepted in both Swedish and English, and you apply via the proposal advert.
• The announced thesis is open only to students affiliated with a Swedish University/College either directly or via an exchange program.
• When the thesis proposal states that it includes two students working together, we would like you to apply in pairs. In these cases, send one application each but make sure to clearly state in your application who your co-applicant is. If you have any questions regarding this, please do not hesitate to contact us.
• Please attach your CV and University/College grade summary.

Who to contact for any questions regarding the position!

Please contact Henrik Liberg, [e-mail], [phone].
