Partition sound attenuation rises with frequency except at coincident resonances, which damping reduces

Evidence

Figures 4.10 and 4.11 provide guidance, even though they were for isolated resonances in an otherwise flat response curve. It can be seen that this bump is several times higher than the detection threshold for the Q = 1 resonance, the closest match. The other medium-Q resonances in (a) are around the anechoic detection threshold, and in a reflective room the threshold will be even lower, so these may be audible in program. — , Toole, Floyd E - Sound reproduction-…, 399 (#expands, via linked claim)

• XREF: connects to: Resonant power dissipation actually grows when damping decreases; Wall damping grows with frequency only as the square root; On resonance, releasing sound reduces its loudness (+5 more)

• Partition mass provides isolation at higher frequencies until coincident resonances degrade it #corroborates (0.90)
• Resonances near anechoic thresholds become audible again in reflective rooms #expands (0.72) — , Toole, Floyd E - Sound reproduction-…, 399
