AWC TR15 Acoustic Calculator

목재 프레임 바닥 및 천장 어셈블리 용 사운드 전송 계산기

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
