  • Title: Consonant identification in N-talker babble is a nonmonotonic function of N.
    Author: Simpson SA, Cooke M.
    Journal: J Acoust Soc Am; 2005 Nov; 118(5):2775-8. PubMed ID: 16334654.
    Abstract:
    Consonant identification rates were measured for vowel-consonant-vowel tokens gated with N-talker babble noise and babble-modulated noise for an extensive range of N, at a fixed signal-to-noise ratio. In the natural babble condition, intelligibility was a nonmonotonic function of N, with a broad performance minimum from N = 6 to N = 128. Identification rates in babble-modulated noise fell gradually with N. The contributions of factors such as energetic masking, linguistic confusion, attentional load, peripheral adaptation, and stationarity to the perception of consonants in N-talker babble are discussed.
