Saliency Map Filtering Background Noise. We measure the salient scores of a region by calculating the color and spatial distance between the regions obtained by superpixel segmentation which match the foreground clue and the regions obtained by superpixel segmentation that do not match the foreground clue.
Unlike the lab process of noisy utterance collection described in the first study, this synthetic means of noisy utterance collection is much more powerful and can be applied to thousands of utterances once the initial background noise and CIRs are collected.
"Hearing new words in fluent speech without a lot of background noise before trying to learn what objects the new words corresponded to may help very young children master new vocabulary," suggests Jenny Saffran, College of Letters & Science Professor of Psychology at the University of Wisconsin-Madison, who coauthored the study.
Predict: How does background noise affect the distance from which you can hear a pin drop?
This study evaluated the impact of noise pollution in the learning environment on student-participants' cognitive performances, assessed the intensity of background noises in their classrooms and homes, and identified the primary sources of the noises.
For Method I (direct assessment with task), five levels of two tonal frequencies (125 Hz and 500 Hz) were tested above two different background noise levels (40 dBA and 55 dBA, with spectra roughly following RC contours of RC-25 and RC-40 respectively) for a total of 20 test signals.
The enhanced voice recognition service, delivered in partnership with Boston-based Interactions Corp, filters background noise out and enables customers to:
The research team, led by DeLiang Wang, professor of computer science and engineering, developed a computer algorithm that analyzes speech and removes most of the background noise. The team found that the algorithm improved hearing-impaired people's comprehension from 25 percent to almost 85 percent against background noise.
It quickly analyzes speech and removes most of the background noise.
The GunSport PRO-15 has the added benefit of 15-dB protection, which activates automatically if continuous background noise reaches unsafe levels.
