Raleigh, NC – The impact of acoustics on human productivity in commercial and industrial buildings is profound. Studies such as one published in Electronic Physician1 have shown that there is a direct and significant association between levels of sound present in an environment and the quality and length of human output. Additionally, both the U.S. Environmental Protection Agency and OSHA have published requirements and standards, respectively, for maximum noise levels in interior spaces, recognizing sound as a significant environmental factor that affects our health. Cue metal building insulation (MBI), which plays a critical role in not only the thermal efficiency of a structure, but the acoustical performance, too.
