Of these, the most significant is Dispersion Technology, which has sold dozens of its acoustic spectrometer systems in the past few years.
Although some acoustic spectrometers function in the audible range, these are typically used for human-voice analysis rather than in lab settings.
Another intriguing new technology at the Innovation Showcase was the laser acoustic spectrometer
, manufactured by Quad Associated Products.
