Effects Of Reverberation And Noise On Speech Comprehension By Native And Non-Native English-Speaking Listeners, Z. Ellen Peng, Lily M. Wang, Siu-Kit Lau, Adam M. Steinbach 2017 University of Nebraska-Lincoln

Effects Of Reverberation And Noise On Speech Comprehension By Native And Non-Native English-Speaking Listeners, Z. Ellen Peng, Lily M. Wang, Siu-Kit Lau, Adam M. Steinbach

Lily M Wang

Previous studies have demonstrated the negative impact of adverse signal-to-noise-ratios on non-native English-speaking listeners' performance on speech recognition using recall tasks, as well as implied that comprehension skills were more impaired than recognition skills under reverberation and noise. The authors have themselves previously conducted a pilot study on three native and three non-native Englishspeaking listeners to examine the effects of reverberation and noise using speech comprehension tasks. Those results suggested that speech comprehension performance is worse under longer reverberation times (RT), and that a longer RT is more detrimental to speech comprehension by non-native listeners than native listeners. This paper ...

How Tonality And Loudness Of Noise Relate To Annoyance And Task Performance” Noise Control Eng. J. 65(2), 71-82., Joonhee Lee, Jennifer M. Francis, Lily M. Wang

Lily M Wang

Audible tones in noise generated by building mechanical equipment can be a leading cause of complaints from occupants. A number of metrics have been developed to quantify prominence of a tone, but previous work has shown that the impact of a certain tonality appears to vary with the level of the broadband noise signal. More work on how tonal signals of varying tonality, tone frequency and broadband noise levels relate to annoyance and task performance is needed. This paper investigates such relationships between current noise metrics, annoyance and task performance under assorted tonal noise conditions through subjective testing. Participants rated ...

Feasibility Analysis Of Recycled-Paper Fueled Agricultural Desalination Process: Design Of Recycling And Desalination Processes, Sean M. Street

Chemical Engineering Undergraduate Honors Theses

While recycled-paper-briquettes have lower BTU ratings than wood, and fresh water is typically a low cost to agricultural entities, situations exist where economic and/or environmental factors may allow a recycled-paper-fueled desalination process to be viable for some specific agricultural entities. This document begins with a discussion of how water is priced throughout India before analyzing trends in the Maize futures market. By tying the two together, an opportunity is created for solution which the remainder of the document presents. Paper waste in India makes-up 50% of its solid waste country-wide; however, only a quarter of that waste is recycled ...

Property Sensitivity Study For Oil Recovery In The Bakken, Daniel Beach 2017 Montana Tech

Property Sensitivity Study For Oil Recovery In The Bakken, Daniel Beach

Graduate Theses & Non-Theses

The upstream (exploration and production) end of the petroleum industry has experienced tremendous success over the past fifteen years by employing innovative ways to drill and stimulate new wells thereby greatly increasing production. Based upon these successes, there has been a shift to unconventional wells, where the cost for drilling and completing wells can be much more expensive. Most unconventional wells target tight rock formations having low permeability and porosity. As a result, these reservoirs require enhanced stimulation to improve recovery operations to establish profitable oil or gas production. These wells are drilled horizontally to maximize contact area in the ...

Uncertainty Of Stereo Piv Calibration And Self-Calibration, Braydon J. Williams

All Graduate Theses and Dissertations

Particle image velocimetry (PIV) is a widely used fluid measurement technique. Three dimensional PIV data or stereo PIV is acquired using two cameras. Stereo cameras are calibrated from camera coordinates, pixels, to real world units such as millimeters using calibration models. Stereo calibration is fundamental to the accuracy of a PIV measurement. In this thesis, the accuracy of the stereo calibration is assessed. The mean error of stereo calibration was found to be 0.23%.
