About This Product!

Description

CornerFills are sections of flat-cut Studiofoam corner acoustic absorbers that are beneficial in 2 ways. Aesthetically, they give you smooth, clean edges against which to butt your acoustic wall treatments and bass traps for a more professional appearance. Acoustically, they smooth out the excess low frequency energy that congregates in room corners.

You can judge a foam's absorptive effectiveness by studying its NRC (Noise Reduction Coefficient), a single number average of a foam's absorption in what was determined long ago to be the most important range. The federally mandated test (ASTM C423) is standardized to cover frequencies between 125Hz and 4000Hz, but when calculating an NRC, only the coefficients from 250Hz to 2000Hz are used to help alleviate the possibility of testing errors.

All Auralex foam products are tested at an independent, unbiased acoustical laboratory ? the oldest, most reliable lab in the country. They insist on using only the very best testing facility because they believe the customers deserve the most accurate absorption coefficient information possible.
