• The use of sound as a means to gather information about our environment has been developed with limited scope over the past several decades. The primary application of this technology has been ultrasound and ultrasonic ranging. Recent developments in nonlinear acoustics have proven that two-tone measurements and directional high frequency parametric arrays can extract much more information about the size, shape, and density of objects under inspection. However, acoustic measurements are difficult to make in the laboratory environment due to excessive ambient noise. For these reasons, the Electronics Research Laboratory at NC State University has constructed an acoustic-RF anechoic chamber as a means to make these measurements and further research in nonlinear acoustics and acoustic detection and imaging.
