‘Something good can be made even better’, Professor of Audio Signal Processing Vesa Välimäki replies when asked why well-functioning speakers are still being studied and improved through research. Aalto University's research projects have involved, for instance, the automatic calibration technology of studio speakers. It ensures a high quality of sound regardless of the room and its location. The most recent study published in cooperation focuses on improving the impulse response of speakers.

‘We modelled the speaker on the computer, which made it possible to test at what point of time certain frequencies come out of the speaker in relation to each other’, says Juho Liski who is working on a doctoral dissertation on the topic.

Cooperation with several companies

It is natural for the acoustics researchers of Aalto University to cooperate with Genelec, as the company’s roots go back to the Helsinki University of Technology, where the company founder studied in the 1970s. In addition to joint research projects, Genelec cooperates with universities in many different ways. The company's representatives give lectures on different courses and the company provides students with opportunities for diploma work and training.

Aalto University’s acoustics researchers also cooperate with other companies, such as Nokia and Huawei. The Aalto Acoustics Lab, which was established a few years ago, has intensified the cooperation between acoustics researchers, such as increasing joint research and student projects, and the number of funding applications.
