Understanding STC vs. OITC: Which Metric Matters?
Comparing two critical acoustic metrics and their real-world applications in urban noise containment.
Frequency Matters
STC measures speech-range noise. OITC measures low-frequency rumble. If your project is near a construction site or railway, OITC is the metric you should focus on.
Glazing Configurations
Asymmetrical glazing (using two different thicknesses of glass) is the most effective way to block broad-spectrum noise.
