AWC TR15 Acoustic Calculator

Calculadora de transmisión de sonido para conjuntos de piso y techo con marco de madera

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
