Continuous noise is played in many open-plan offices to partially mask ambient sounds, in particular background speech. With this, the detrimental impact of background sounds on cognitive performance is intended to be reduced as well as subjectively perceived disturbance. Our experiments explored whether background music can achieve the same effects. Besides collecting subjective rating data, we tested cognitive performance using verbal serial recall. This is the standard task for exploring verbal short-term memory, which is central to human information processing. Either staccato music, legato music or continuous noise was superimposed on office noise. In Experiment 1 (N ¼ 30), only continuous noise reduced the detrimental impact of office noise significantly. Legato music did not qualify in this respect although it did not diminish cognitive performance when presented in isolation in Experiment 2 (N ¼ 20). Subjective ratings in both experiments revealed that most participants would prefer legato music to continuous noise in office environments.

The functional relations among motor-based prediction, sensory goals and feedback in learning non-native speech sounds: Evidence from adult Mandarin Chinese speakers with an auditory feedback masking paradigm

Previous studies in speech production and acquisition have mainly focused on how feedback vs. goals and feedback vs. prediction regulate learning and speech control. The present study investigated the less studied mechanism–prediction vs. goals in the context of adult Mandarin speakers’ acquisition of non-native sounds, using an auditory feedback masking paradigm. Participants were asked to learn two types of non-native vowels: /ø/ and /ɵ/—the former being less similar than the latter to Mandarin vowels, either in feedback available or feedback masked conditions. The results show that there was no significant improvement in learning the two targets when auditory feedback was masked. This suggests that motor-based prediction could not directly compare with sensory goals for adult second language acquisition. Furthermore, auditory feedback can help achieve learning only if the competition between prediction and goals is minimal, i.e., when target sounds are distinct from existing sounds in one’s native speech. The results suggest motor-based prediction and sensory goals may share a similar neural representational format, which could result in a competing relation in neural recourses in speech learning. The feedback can conditionally overcome such interference between prediction and goals. Hence, the present study further probed the functional relations among key components (prediction, goals and feedback) of sensorimotor integration in speech learning.

“…Of those six types, Pink and Babble are the conventional types of masker that have been commonly used for speech masking [35,36]. Since generation of these masker do not require the target speech as a seed, their properties are also independent from that of the target speech.…”
