Abstract
OBJECTIVE: Werner and Bargones (1991) observed that a 4-10-kHz noise band can mask a 1-kHz signal during infancy. The purpose of this study was to examine whether remote-noise masking extends into the school-aged years. DESIGN: Listeners were 4-6-yr-olds, 7-9-yr-olds, and adults. Detection thresholds were measured for the 1-kHz signal in quiet and in the presence of the remote-frequency noise. In separate conditions, masker level was either 40 or 60 dB SPL. RESULTS: On average, thresholds for the 1-kHz signal were elevated in the presence of the remote-frequency noise for 4-6-yr-olds, but not for 7-9-yr-olds or adults. Group average thresholds were similar across masker levels, indicating nonperipheral effects. CONCLUSIONS: Susceptibility to remote-frequency masking in children extends to 4-6 yrs of age for some children.
