Kalkulator penghantaran bunyi untuk lantai kayu dan perhimpunan siling
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
