Acoustical Measurements
Research on acoustical measurements support our work on spatial audio and head-related acoustics. Currently, we are studying the use of laser-induced sparks as a novel sound source for acoustical measurements.
The advantage of this method is that it has features very close to an ideal point source, i.e., omnidirectional radiation pattern, no mass, wide frequency band, and high sound pressure level. This can be applied to scale models and in general acoustical measurements. In addition, we have performed research on the effect of wind on speech transmission.
