AB  - PURPOSE: The aim of this study was to investigate developmental and noise-induced 
      changes in central auditory processing indexed by event-related potentials in 
      typically developing children. METHOD: P1, N2, and N4 responses as well as 
      mismatch negativities (MMNs) were recorded for standard syllables and consonants, 
      frequency, intensity, vowel, and vowel duration changes in silent and noisy 
      conditions in the same 14 children at the ages of 2 and 4 years. RESULTS: The P1 
      and N2 latencies decreased and the N2, N4, and MMN amplitudes increased with 
      development of the children. The amplitude changes were strongest at frontal 
      electrodes. At both ages, background noise decreased the P1 amplitude, increased 
      the N2 amplitude, and shortened the N4 latency. The noise-induced amplitude 
      changes of P1, N2, and N4 were strongest frontally. Furthermore, background noise 
      degraded the MMN. At both ages, MMN was significantly elicited only by the 
      consonant change, and at the age of 4 years, also by the vowel duration change 
      during noise. CONCLUSIONS: Developmental changes indexing maturation of central 
      auditory processing were found from every response studied. Noise degraded sound 
      encoding and echoic memory and impaired auditory discrimination at both ages. The 
      older children were as vulnerable to the impact of noise as the younger children.
