WhisperWave® Clouds installed at UVA OpenGrounds

The new UVA OpenGrounds facility required acoustical treatment to lower reverberation and improve speech intelligibility. The architect decided on Whisperwave Clouds from Acoustical Solutions, which blended with the aesthetic design and enhanced the acoustical quality of the space.

What is HPC Coating?

HPC is a high performance coating that is applied to acoustical foam. This improves the durability of the material and provides a surface that can be cleaned using a damp cloth.
