Speech recognition in noise is harder in second L2 than first languages L1. This could be because
noise disrupts speech processing more in L2 than L1, or because L1 listeners recover better though
disruption is equivalent. Two similar prior studies produced discrepant results: Equivalent noise
effects for L1 and L2 Dutch listeners, versus larger effects for L2 Spanish than L1. To explain
this, the latter experiment was presented to listeners from the former population. Larger noise effects
on consonant identification emerged for L2 Dutch than L1 listeners, suggesting that task factors
rather than L2 population differences underlie the results discrepancy.
