Acoustics in production

The Acoustics lab is part of our research within problems that arise in the interaction between humans and machines, but also among humans and within machine optimisation. We provide both general and tailor-made solutions on concrete issues.

The CIE Acoustics lab is built around the central concept of sound quality assessment. Our environment is getting louder and louder, and both the noise sources and their sound characteristics are becoming ever more diverse. At the same time, digital mass media and global markets give the power of the human voice a whole new meaning. Our equipment meets these challenges of the twenty-first century. We can produce, record and measure sound multidimensionally and multiparametrically; and, in each of these contexts, we can analyse patterns of human behaviour, physiology and speech. The issues that we can address on this basis reach from noise reduction through the optimisation of robot and machine sounds to voice interfaces and public-speaker (presentation and negotiation) training.
Accordingly, the laboratory is divided into 3 sections: (1) a sound-treated booth, (2) a surround sound acoustic-ambiance simulation environment with virtual reality immersion and (3) a perceptual area for interactive psychoacoustic experiments.


Services for companies

Sound-related services

Noise-related services
  • Noise-source localisation
  • Noise measurement and analysis, also as a preparation for certification
  • Noise assessment in terms of how stressful/distracting/dangerous it is for humans and for human health (with advice for improvement)
Speech related services
  • SDU Acoustic Charisma Training; the world's first presentation/public speaking training that is based on acoustic signal analysis and strictly rooted in scientific grounds; taught in combination with acoustic signal visualisation, body language and general voice and breathing training
  • Negotiation training, also based on acoustic voice analysis and training


  • Acoustic lab
