Relating to a technique in which a beam of light passing through a gaseous medium is capable of generating sound if the beam is periodically interrupted at some characteristic sound frequency: When Bryan was studying acoustics in his physics class, he experimented with a laser beam and was able to generate sound waves in gas by measuring the sounds that were generated by the optoacoustic effects at the frequencies of the interruptions of the light beam.
