Description
The world of a hearing impaired person is much different than that of somebody capable of discerning different frequencies and magnitudes of sound waves via their ears. This is especially true when hearing impaired people play video games. In most video games, surround sound is fed through some sort of digital output to headphones or speakers. Based on this information, the gamer can discern where a particular stimulus is coming from and whether or not that is a threat to their wellbeing within the virtual world. People with reliable hearing have a distinct advantage over hearing impaired people in the fact that they can gather information not just from what is in front of them, but from every angle relative to the way they're facing. The purpose of this project was to find a way to even the playing field, so that a person hard of hearing could also receive the sensory feedback that any other person would get while playing video games To do this, visual surround sound was created. This is a system that takes a surround sound input, and illuminates LEDs around the periphery of glasses based on the direction, frequency and amplitude of the audio wave. This provides the user with crucial information on the whereabouts of different elements within the game. In this paper, the research and development of Visual Surround Sound is discussed along with its viability in regards to a deaf person's ability to learn the technology, and decipher the visual cues.

Description
Multiple-channel detection is considered in the context of a sensor network where data can be exchanged directly between sensor nodes that share a common edge in the network graph. Optimal statistical tests used for signal source detection with multiple noisy sensors, such as the Generalized Coherence (GC) estimate, use pairwise measurements from every pair of sensors in the network and are thus only applicable when the network graph is completely connected, or when data are accumulated at a common fusion center. This thesis presents and exploits a new method that uses maximum-entropy techniques to estimate measurements between pairs of sensors that are not in direct communication, thereby enabling the use of the GC estimate in incompletely connected sensor networks. The research in this thesis culminates in a main conjecture supported by statistical tests regarding the topology of the incomplete network graphs.

Description
This study explores the connection between hearing impairment, workplace (social, performance, and employer) stressors, and self-efficacy beliefs. The aim was to compute the statistical significance, direction, and strength between specific stressors and self-efficacy beliefs to see how individuals manage workplace stress overall. In addition, the literature review and a qualitative analysis of open-ended responses from six participants were examined to determine effective coping mechanisms. Descriptive quantitative analysis, frequency charts, t-tests, correlational matrices, and ANOVAs were used to calculate relationships between demographics, stress, and self-efficacy ratings. The results show that self-efficacy and stress are negatively correlated and that self-efficacy and coping techniques are positively correlated. In addition, positive work experiences are correlated with lower stress and higher self-efficacy. Amongst workplace stressors, social stress outranks performance and employer stressors. The opposite trend shows in workplace self-efficacy where performance and employer self-efficacy beliefs are greater than social self-efficacy. Hearing loss level and communication style (e.g., speech, lip reading, sign language) were two important demographic factors in determining stress and self-efficacy levels. Effective coping mechanisms that participants reported included mindfulness, and breaks, whereas ineffective coping included avoidance coping.

Description
Lossy compression is a form of compression that slightly degrades a signal in ways that are ideally not detectable to the human ear. This is opposite to lossless compression, in which the sample is not degraded at all. While lossless compression may seem like the best option, lossy compression, which is used in most audio and video, reduces transmission time and results in much smaller file sizes. However, this compression can affect quality if it goes too far. The more compression there is on a waveform, the more degradation there is, and once a file is lossy compressed, this process is not reversible. This project will observe the degradation of an audio signal after the application of Singular Value Decomposition compression, a lossy compression that eliminates singular values from a signal’s matrix.
