Acoustical Testing

As part of our commitment to lead the industry in the technology of acoustics, we built an acoustical testing laboratory in 1969. The Hufcor acoustical lab is accredited by the U.S. Department of Commerce National Voluntary Laboratory Accreditation Program (NVLAP). Under the guidelines of the NVLAP accreditation, our certified testing professionals, and state-of-the-art equipment are available to perform, on-site field testing that ensures your panels are performing to their promised sound transmission (STC/NIC) and sound absorption (NRC) standards.
