NOISE REDUCTION
Acoustic Treatment - noise control within a space
Monoglass® Spray-On provides aesthetics and excellent reverberation control in:
- Night clubs
- Television and film studios
- Auditoriums
- Gymnasiums & sport facilities
- Theaters
- Factories and machine shops
- Restaurants
- Offices and retail shops
Monoglass Spray-On’s low compressive strength glass fiber produces noise reduction coefficients greater than many other insulations. This capability reduces airborne noise transmitted through the structure from external sources and provides superb absorption of internal airborne sound.
Monoglass can be applied in several standard colors, or painted with an appropriate acoustic paint with minimal effect on the NRC or STC ratings.
Project Profile - Wembley Indoor Sport Stadium
Noise reverberation time can be greatly reduced with a minimal application of Monoglass, as demonstrated in the Wembley Indoor Sport Stadium, Johannesburg, South Africa. Treated with only 1” / 25 mm of Monoglass, the graph (right) depicts the reverberation times with 0% occupancy measured before and after treatment. This shows a considerable reduction in reverberation time over the entire frequency range, which resulted in major improvements in speech intelligibility.
Before treatment, speech conversations more than 61⁄2 feet / 2 meters was very difficult. After treatment, even with the hall empty (no audience), conversation can now be conducted without any special effort.
