Spanish is better than English for discriminating Portuguese vowels: acoustic similarity versus vowel inventory

Frontiers in Psychology, 2014
Second language (L2) learners often struggle to distinguish sound contrasts that are not present in their native language (L1). Models of non-native and L2 sound perception claim that perceptual similarity between L1 and L2 sound contrasts correctly ...

Investigation of the adequacy of the acoustic field model in the closed space

Journal of Vibroengineering, 2013
In order to model the sound propagation as adequately as possible in the closed space and its interaction with obstacles, the assessment of several excitation sources and the sound transmission through the obstacle should be taken into account, which is very important when the direct field of sound pressure is predominant if compared to the reflected ...
