Waterfall diagrams alone poorly estimate the audibility of resonances

Evidence

All these studies indicate that parametric equalization based on high resolution steady-state frequency responses is a reliable method to attenuate bothersome room resonances. Waterfall diagrams alone are of little value in estimating the audible consequences of resonances. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1654

Categorization

• XREF: Contradicts the common industry habit of relying on waterfall/Cumulative Spectral Decay plots to judge room-mode audibility — relevant to the reader’s modeling of modal behavior. — connects to: High-frequency-resolution waterfalls falsely suggest uncontrolled ringing; Standard acoustic diagrams poorly match natural human hearing instincts and cause confusion — Schafer, Murray R, The Soundscape- Our Sonic Environment…, 431
• corroborated: 2 independent passages support this claim — Toole, Floyd E, Sound reproduction- the acoustics and…, 1654
