Reverberation time maps directly onto equivalent signal-to-noise ratio

Evidence

Figure 17.10 shows the effect of the SNR on the STI and also the effect of ideal reverberation with different T60 values. Since the curves are on top of each other, the correspondence of the SNR to the reverberation time is easily seen. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2426

• XREF: Connects to the noise and acoustics reading everywhere in this library — reverberation degrading intelligibility is equivalent to additive noise in STI terms.
• SEED: Angle for an essay: reverberation is speech’s ‘acoustic noise’ — a measurable equivalence between room reflections and additive interference that lets architects design for intelligibility.
