Sound insulation and vibration tests for lightweight steel framing floors
2000 (English)Report (Other academic)
An experimental study of sound insulation and vibrations of lightweight steel framing floors due to different floor construction set up were performed. Floors with 3m, 5m and 7.2m span were tested. The impact and airborne sound insulation for 3m span floor were measured based on ISO 140 in lab condition. Vibration tests were carried out on all three different spans. The vibration transmission loss of the structure was determined from the surface vibration measurements. The fundamental natural frequency and damping of the structure was obtained from the mobility measurements. The results of the experiments from sound insulation tests for 3m span lightweight steel framing floor show that this type of floor has very good acoustic performance. The comparison of the measurements of the vibration transmission loss from 3m, 5m and 7.2m show that the floors also have good vibration reductions in longer spans.
