The 1” panel is designed to absorb frequencies in the speech range and higher. These panels are great for boardrooms and classrooms where the only sound created is from voices.
The 2" panel is designed to absorb frequencies in the speech range and higher. These panels are great for boardrooms and classrooms where the only sound created is from voices.
The 3” panel is designed to absorb frequencies in the speech range and higher. These panels are great for boardrooms and classrooms where the only sound created is from voices.
