Preliminary investigation of the short-term in situ performance of an automatic masker selection system

Soundscape augmentation or ``masking'' introduces wanted sounds into the acoustic environment to improve acoustic comfort. Usually, the masker selection and playback strategies are either arbitrary or based on simple rules (e.g. –3 dBA), which may lead to sub-optimal increment or even redu...
