Abstract The effect of the resilience of the steel studs on the sound insulation of steel stud cavity walls can be modelled as an equivalent translational compliance in simple models for predicting the sound insulation of walls. Previous determinations of this equivalent translational compliance have only been made for 25 gauge steel studs with the height of rooms in a typical house. This paper extends the determination of the equivalent translational compliance to steel studs with steel gauges of 16, 18, 20 and 25 and heights of 2.44 and 4.57 m in walls with stud spacing of both 0.406 and 0.61 m. The equivalent compliance is determined for both line connection and point connection models. The sound insulation of walls predicted using these values of compliance is compared with experiment. Unfortunately, big differences and variations occur between prediction and experiment at 125 and 160 Hz. These big differences occur because of the deep dip in the experimental measurements that occurs with thicker steel studs and wooden studs which was observed experimentally by Bradley and Birta in the laboratory and theoretically by Lin and Garrelick. This dip is not predicted by the simple sound insulation theory of Davy used in this paper.
