Figure 1: The graph represents how much sound transfers between floors for each assembly type and is shown versus specific frequency (bass, mid, treble, etc.). The sound travels differently depending on frequency and this graph represents how it varies between typical concrete, mass timber, and a mass timber built up with concrete. The blue line is the concrete sound transmission and the grey is the mass timber with concrete. Higher levels on the graph indicate a better sound isolation between the two floors. At low frequency (bass), the sound isolation performance reduces, and is worse in this range. At mid/high frequency, the mass-timber with concrete assembly performs better.
