Conversation tolerance rises by one only after 3-4 dB SNR improvement
Evidence
On average, participants were not prepared to tolerate an additional conversation until the SNR had increased by at least 3 dB, and not prepared to tolerate more than one extra conversation until a 4 dB change in SNR, similar to the results in Sect. 3.1 . Though a change of one conversation is an arbitrary change, it is arguably a less arbitrary unit of meaningfulness than one point on a better/worse rating scale. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5697
