Effects Of Noise, Reverberation And Foreign Accent On Native And Non-Native Listeners’ Performance Of English Speech Comprehension, Zhao Ellen Peng, Lily M. Wang 2016 University of Nebraska - Lincoln

Effects Of Noise, Reverberation And Foreign Accent On Native And Non-Native Listeners’ Performance Of English Speech Comprehension, Zhao Ellen Peng, Lily M. Wang

Lily M Wang

A large number of non-native English speakers may be found in American classrooms, both as listeners and talkers. Little is known about how this population comprehends speech in realistic adverse acoustical conditions. A study was conducted to investigate the effects of background noise level (BNL), reverberation time (RT), and talker foreign accent on native and non-native listeners' speech comprehension, while controlling for English language abilities. A total of 115 adult listeners completed comprehension tasks under 15 acoustic conditions: three BNLs (RC-30, RC-40, and RC-50) and five RTs (from 0.4 to 1.2 s). Fifty-six listeners were tested with speech ...


Design And Optimization Of Membrane-Type Acoustic Metamaterials, Matthew G. Blevins 2016 University of Nebraska-Lincoln

Design And Optimization Of Membrane-Type Acoustic Metamaterials, Matthew G. Blevins

Architectural Engineering -- Dissertations and Student Research

One of the most common problems in noise control is the attenuation of low frequency noise. Typical solutions require barriers with high density and/or thickness. Membrane-type acoustic metamaterials are a novel type of engineered material capable of high low-frequency transmission loss despite their small thickness and light weight. These materials are ideally suited to applications with strict size and weight limitations such as aircraft, automobiles, and buildings. The transmission loss profile can be manipulated by changing the micro-level substructure, stacking multiple unit cells, or by creating multi-celled arrays. To date, analysis has focused primarily on experimental studies in plane-wave ...

The Burning Building | Fire As Place, Winnie Tu 2016 Syracuse University

The Burning Building | Fire As Place, Winnie Tu

Architecture Senior Theses

The importance of fire in human social evolution is widely acknowledged but the extent of its impact is not fully explored. Generally, it is connected to energy, light, purification, illumination, creation, destruction and metamorphosis. Fire’s paradoxical nature has built up many societies throughout human history and has been the primary social driver within communities. Due to technological advances, its energy has been transformed into a distant element which is being used discretely in industrial buildings, hidden under basements, or replaced by other forms of energy. Now, heat, energy, and light is readily available anywhere at any time, eliminating the ...


Uncreative Construction | Domestic Mutations In America, Sean Morgan 2016 Syracuse University

Uncreative Construction | Domestic Mutations In America, Sean Morgan

Architecture Senior Theses

A shift in residential patterns in American cities have fostered a breeding ground for mutant buildings. Owners split, manipulate, and expand their houses as they create idiosyncratic constructs of great visual and spatial complexity. Originally developed for a middle class population, single-family homes have become mixed-use or multi-family complexes thanks to the resourceful implementation of commercial materials.

This thesis aims to develop a new strategy for transforming the normative American house by using the conventions of platform frame construction. Variations will emerge from a set of design constraints, which—unlike that employed for typical houses—are based on data that ...


The Renaissance Of The Railway | Towards A Global High-Speed System, Xiaoyu Li 2016 Syracuse University

The Renaissance Of The Railway | Towards A Global High-Speed System, Xiaoyu Li

Architecture Senior Theses

The railway has shown its unique character as a mode of transportation since its invention in Europe during the Industrial Revolution. In the beginning, its carrying capacity made it stand out, transforming human behavior, and stimulating economic productivity. During the 20th century, air travel, the railways, and long-distance road networks have shared the burden of human transportation - in many countries the car and plane have won out. In recent decade, however, new interest in the railway's potential has been generated as a result of the emergence of new technologies like high-speed rail and the maglev system. Greater speeds are ...


Multidimensional Dialogue Through Architecture | An Exploration Of The Possible Dialogue Between Humans And Walls, Fengqi Li 2016 Syracuse University

Multidimensional Dialogue Through Architecture | An Exploration Of The Possible Dialogue Between Humans And Walls, Fengqi Li

Architecture Senior Theses

This thesis proposes that architectural design no longer has to be primarily static, but rather it can be dynamically responsive to multiple information streams and conditions.

Multidimensional Dialogue Through Architecture is developed from the understanding of human factors and ergonomics. The dispersed works on research and inference are different ways to explore the interaction between the discipline of architecture and the other fields, such as psychology, engineering, bio-mechanics, physiology, cognitive science, and anthropomorphic. Therefore, the purpose of this thesis is not to design a specific building that works perfectly in particular conditions but rather to use architectural elements to mediate ...


Algorithmic Settlements | Modeling Informal Settlement Through Automated Generative Design, Ben Anderson-Nelson 2016 Syracuse University

Algorithmic Settlements | Modeling Informal Settlement Through Automated Generative Design, Ben Anderson-Nelson

Architecture Senior Theses

The position of the architect when designing is to arbitrate which information is relevant and which is not, and to do so across a broad spectrum of fields. Considering this, Christopher Alexander claimed as long ago as 1964, that “design problems are reaching insoluble levels of complexity.”This thesis focuses on informal settlement growth and how architects can investigate growth as a part of master-planning new housing. Drawing on case studies of settlements, video game logics, and existing architectural tools, a tool was developed to study the growth of settlements. This tool is based on cellular automata, a spatial and ...


Never-Land | A Parasitic And Accumulative Approach To Urbanization In China, Xiaoyan Dong 2016 Syracuse University

Never-Land | A Parasitic And Accumulative Approach To Urbanization In China, Xiaoyan Dong

Architecture Senior Theses

Ever since 1960s, European situationist and Japanese metabolist architects constantly reject the uniformity and totalitarian of modern architecture/urban design, seeking parasitic and dynamic approaches to post-war urbanization. Projects such as the Plug-In City and the Tokyo Bay dream of alternative urban scenarios by reversing traditional perceptions of infrastructure’s role in the city, combining architecture, technology and society together. However, these megastructure projects not only neglect the existing urban context but also lack political and economic driving force. As a result, they are considered utopian by many contemporary critics.

Fifty years later in China, fast urbanization process creates problems ...


The Seed | Urban Vertical Farming Germinated, Michael Lima 2016 Syracuse University

The Seed | Urban Vertical Farming Germinated, Michael Lima

Architecture Senior Theses

A city works as an ecosystem in many ways. However, we currently do not live within that ecosystem, as the difference between an ecosystem and a city is the waste output and food input . Nature and society do not exist independently because there are no spaces of nature unaffected by man. With this in mind we need to reestablish our relationship with nature. Architecture and engineering can be used to create buildings that will allow humans to turn cities into ecosystems. This thesis argues that Urban Vertical Farms will produce social and economic hubs that will be a new way ...


Innie/Outie | Renegotiating Figure And Structure, Maxwell Rosner 2016 Syracuse University

Innie/Outie | Renegotiating Figure And Structure, Maxwell Rosner

Architecture Senior Theses

This thesis contends that in order to sustain its claim to be socially progressive and accessible enterprise, the discipline of architecture must resist the divorce of figure and structure.

Innie/Outie considers Architecture as a simultaneously typological and teleological proposition. Architects exploit typology as a means of classifying, diagramming, and ultimately flattening and iconicizing ideas about Architecture so as to place them within a broader cultural context, thereby making them intellectually accessible to their audiences. By contrast, architects from the advent of Modernism onwards have displayed a critical preoccupation with the discipline’s teleological potential, the creation of form that ...


Two Lands, One System | Redefining The Border Crossing, Matthew Trulli 2016 Syracuse University

Two Lands, One System | Redefining The Border Crossing, Matthew Trulli

Architecture Senior Theses

The Israeli and Palestinian populations each have their own distinct infrastructural system, which operates independently and fails to connect the people in this region. This thesis contends that if a two-state solution is implemented under the guidelines of the 2003 Geneva Accord, new connections can stitch the populations of Israel and Palestine together through a reimagined border system.

These divisive infrastructural networks, which are a result of tense relationships, have also sparked increased violence throughout the region, particularly in Jerusalem. The French Hill, located north of the Old City in Jerusalem, is positioned at a critical point in the infrastructural ...


Subtraction | Construction In Reverse, Sherina S. Zhang 2016 Syracuse University

Subtraction | Construction In Reverse, Sherina S. Zhang

Architecture Senior Theses

The life of a building does not begin at the creation of the new; it starts with the subtraction of the old. As the pace of technological development accelerates, buildings are erected and demolished at an unprecedented rate. Cities use their urban artifacts like skyscrapers, to portray economic and political prowess. For example, the ghost cities of China are relics of a burst financial bubble while Venezuelan ruling party elites name business towers after themselves as a show of power and prosperity. Many parts of the world today are now overbuilt with artifacts that decline into obsolescence. Demolition procedures erase ...


Free Encounters | Giving Form To The Informal Workplace, Ryan Williams 2016 Syracuse University

Free Encounters | Giving Form To The Informal Workplace, Ryan Williams

Architecture Senior Theses

This thesis contends that the "office" as a solely economic construct is no more: Its utility as an engine driving productivity and the accumulation of capital has stalled in our present age of information where value is constructed through knowledge exchange and interaction.

Via the use of new technologies, millennial workers' transition from the college campus to the office has become more seamless and, this thesis argues, it is in this paradigm shift that it is possible to identify a blurring of the public and private spheres. The millennial worker-turned-freelancer's life exists forever suspended between work and play, place ...


Private Room Of The Wheel | A New Form Of Transient Dwelling, Kathy Teng 2016 Syracuse University

Private Room Of The Wheel | A New Form Of Transient Dwelling, Kathy Teng

Architecture Senior Theses

The cross-country highway and road trip are deeply rooted in the American psyche, supported by the rapid growth in ownership of automobiles by American families since the 1940s, establishing a sense of freedom and leisure in their mobile lifestyles. However, other highway users have less control and freedom over their daily routine. These users are part of a vast network of international commerce reliant on the long haul.

The time long-haul truck drivers are away from home is prolonged, with the end of each day spent sleeping in fixed truck cabins and eating at banal truck stops. “ ‘I can be ...


Determining Annoyance Thresholds Of Tones In Noise, Jennifer M. Francis, Joonhee Lee, Lily M. Wang 2016 University of Nebraska - Lincoln

Determining Annoyance Thresholds Of Tones In Noise, Jennifer M. Francis, Joonhee Lee, Lily M. Wang

Lily M Wang

Building services equipment often produces noise signatures with significant tones in them that can lead to complaints in the built environment. Previous studies have investigated prominence levels of assorted tonal frequencies, but it is still unclear what prominence of the tones across varying tonal frequencies can lead to human annoyance. This project seeks to apply two different methods towards defining annoyance thresholds of tones in noise at two tonal frequencies: 125 Hz and 500 Hz. In the first, subjects are asked to perform a task, while exposed to ten minutes of a broadband noise spectrum with a specific level of ...


Assessment Of Noise-Induced Annoyance By Tones In Noise From Building Mechanical Systems, Joonhee Lee, Lily M. Wang 2016 University of Nebraska - Lincoln

Assessment Of Noise-Induced Annoyance By Tones In Noise From Building Mechanical Systems, Joonhee Lee, Lily M. Wang

Lily M Wang

Prominent tones in noise generated by mechanical equipment in buildings can cause complaints from occupants in buildings. The ISO 1996-2 and ANSI S1.13 standards describe methodologies and metrics to quantify tonality perception, but the influence of tones in noise on human annoyance and performance is not fully understood yet. This paper investigates annoyance responses of humans while exposed to background noise with tonal components. Twenty participants completed digit span tasks while exposed to noise signals with differing levels of tones and overall loudness. Subjects were also asked to rate their annoyance after completing tasks under each noise signal. The ...


The Impact Of Building Acoustics On Speech Comprehension And Student Achievement, Lily M. Wang 2016 University of Nebraska - Lincoln

The Impact Of Building Acoustics On Speech Comprehension And Student Achievement, Lily M. Wang

Lily M Wang

The movement for improved classroom acoustics has primarily been grounded on studies that show how building acoustics (i.e. background noise levels and room reverberation) affect speech intelligibility, as determined by speech recognition tests. What about actual student learning, though? If students do not understand each spoken word in the classroom perfectly, can they still manage to achieve high scholastic success? This presentation will review two recent studies conducted at the University of Nebraska – Lincoln, linking classroom acoustic conditions to student learning outcomes and speech comprehension (rather than simply recognition). In the first, acoustic measurements in two public school districts ...
