Lancaster Dispensing Company Acoustical Case Study
| Before | After | |
| Reverberation Time(RT) | 0.9 Seconds | 0.5 Seconds |
| RT Reduction | - | 44% |
| 72dB (15-25 people) | 65 dB (15-25 people) | |
| Occupied Noise Level in Decibels(dB) | 72 dB (25-30 people) | 67 dB (25-30 people) |
| 72 dB (30-35 people) | 71 dB (30-35 people) |
Acoustical Performance
Total acoustical absorption for a suspended ceiling is calculated by multiplying the exposed surface area by the material NRC while “space absorbers” are directly measured. The installation of MetalWorks Tin extra microperforated panels in a reverberant space can significantly reduce the background noise and reverberation time, enhancing speech intelligibility. This can be extremely useful in high-traffic retail and hospitality spaces.
