N2 - The characteristics of using a laser-induced spark as a
monopole source in scale model measurements were assessed by comparison
with an electric spark and a miniature spherical loudspeaker.
Room impulse responses of first order directivity sources were synthesized
off-line using six spatially distributed sparks. The source steering
direction was scanned across the horizontal and vertical plane to assess
the origin of early reflections. The results confirm that the characteristics
of the laser-induced spark outperform those of typical sources. Its
monopole characteristics enable the authors to synthesize room
responses of directional sources, e.g., to obtain directional information
about reflections inside scale models.
