AWC TR15 Acoustic Calculator

Based upon the data and methodologies compiled in American Wood Council's Technical Report No. 15 (TR15), this calculator simplifies the calculation of sound transmission through wood-frame floor and ceilings. Sound transmission class (STC) and Impact insulation class results are given as well as the following detail data at ⅓ octave band center frequency ranging from 125 Hz to 4000 Hz:

TL / STC:
- Floor Layer Estimated Transmission Loss
- Ceiling Layer Estimated Transmission Loss
- System Effect
- Estimated Transmission Loss
- ASTM E413 Reference Contour
- STC shifted Reference Contour
- Estimated Transmission Loss Deficiencies

ISPL / IIC:
- STC Transmission Loss
- ISPL Adjustment
- Estimated Impact Sound Pressure Level
- ASTM E989 Reference Contour
- Shifted Reference Contour
- Impact Insulation Deficiencies
