Acoustic System Performance Evaluation Lab
Machine-translated · View original
A lab exploring methods for measuring and evaluating the performance of acoustic systems such as loudspeakers.
AboutAbout the lab
Designing measurement methods to match how sound is emitted.
Associate Professor Kazuhiko Kawahara studies performance evaluation of acoustic systems such as loudspeakers.
Measuring the characteristics of loudspeakers whose radiation mechanism differs from that of conventional electrodynamic loudspeakers is considered to require new measurement methods.
The lab examines evaluation methods that use measurements such as directivity and sound intensity.
The lab also conducts research on conveying applause in live viewing, and on education in technical ear training, which develops sensitivity in telling sounds apart.
Key terms
- Distributed mode loudspeaker
- A type of loudspeaker whose radiation mechanism differs from that of conventional electrodynamic loudspeakers. Its sound is highly diffuse
- Directivity
- A property that describes how the sound emitted from a loudspeaker varies with direction
- Technical ear training
- Systematic training that raises sensitivity in telling apart differences in sound, such as in frequency and sound pressure
ResearchResearch themes
The lab studies methods for evaluating the performance of acoustic systems such as loudspeakers. It also lists transmission of applause sounds and curriculum development for technical ear training as research themes.
*Illustrative imageMethods for Evaluating Loudspeaker Performance
The lab examines methods for appropriately evaluating the characteristics of loudspeakers whose radiation mechanism differs from that of conventional types, such as distributed mode loudspeakers. It uses measurements such as directivity and sound intensity.
*Illustrative imageMeasuring Sound with Continuous Measurement Methods
The lab proposes a method that records while rotating a loudspeaker on a turntable, measuring how the sound radiates in all horizontal directions in a short time. It also covers methods for measuring acoustic characteristics at multiple locations while moving.
*Illustrative imageLive Viewing Using Applause Sounds
A paper reports the development of a system that returns the applause of the audience at a viewing venue to the live venue with low latency, along with a subjective evaluation confirming that it enhances the sense of unity. The lab also has research on reproducing applause with flat-panel loudspeakers.
*Illustrative imageEducation in Technical Ear Training
The lab works on systematic training programs that raise sensitivity in telling apart differences in sound, such as in frequency and sound pressure. It also reports on efforts to transfer Kyushu University's curriculum to companies, and on a training system conducted online.
