SONEXsuper™ Wedges can dramatically improve the accuracy of sound measurements by eliminating bounce-back sounds such as echo, feedback and resonances.

Designed to be used in situations where low-frequency issues are a problem, SONEXsuper Wedges are most often found in anechoic test chambers. These 12 " x 12" wedges are 6 inches thick and feature an exaggerated, yet symmetrical, anechoic wedge pattern.

To achieve free-field conditions within an acoustic test environment for the measurement of radiated sound power and directivity, the testing area must be free from reverberation, feedback and resonance throughout the audible frequency spectrum. illbruck's SONEX® Wedges, cut in a variety of sizes and shapes, are effective materials for use in anechoic and hemi-anechoic chambers. The acoustical wedges absorb the kinetic energy created by the sound waves. At the same time, the large surface formed by the wedges increases the total absorptive area to absorb even the long wavelengths of low frequency sound.
