Using state of the art measuring equipment, including calibrated Bruel & Kjaer laboratory microphones, MLSSA, CLIO, and Smaart analyzers, and a Linear-X turntable, along with high powered amplifiers, plane wave tubes, and ground plane indoor and outdoor measurement facilities, we can accurately measure loudspeakers, microphones, and headphones.
We can also do field acoustic measurements including environmental noise, long distance sound propagation, suppressor comparisons, vehicle drive-by noise, etc.
We also can accurately test and characterize analog and digital electronics, using our Audio Precision System Two Cascade Dual Domain Analyzer, Tektronix oscilloscopes, and high resolution 6.5 digit DMMs and counters.
Psychoacoustics is the field of scientific analysis of human perception of auditory events.
One example, is double blind testing of a sample of music, one played back at 192kH z with 24 bit resolution, versus one played back at 44.1 kHz at 16 bit resolution.
An ABX Comparator is used to keep track of the subject's scores, and a statistical test is performed to determine significance.
