Minimize Sound Transfer
Sound isolation in construction involves the use of various materials and techniques to minimize the transmission of sound from one space to another. Marino\WARE offers a range of high-performance products designed to minimize sound transmission in wall assemblies, achieving high sound transmission classification (STC) ratings.
Primary Methods for Increasing STC
- Adding Mass
- Decoupling
- Dampening
| STC | Common Sounds Still Heard |
| 35 | Normal voices in adjacent space audible and intelligible most of the time. Raised voices fully intelligible. |
| 40 | Normal voices in adjacent space audible and intelligible some of the time. Raised voices mostly intelligible. |
| 45 | Normal voices in adjacent space audible but unintelligible most of the time. Raised voices partially intelligible. |
| 50 | Normal voices in adjacent space barely audible. Raised voices audible but mostly unintelligible. |
| 55 | Normal voices in adjacent space not audible. Raised voices barely audible but not intelligible. |
| 60 | Raised voices not audible. Loud sounds (e.g.: musical instruments, sterile, TV, etc.) can be heard but notably reduced |
