The purpose of this paper is to determine whether noise is affected by psychological factors rather than simply by physical metrics. For example, personality type, age, perceived control and screening ability were explored, as well as the choice of primary workplace.

An online survey was conducted which resulted in 517 valid responses. The survey included the personality profiling along with questions related to noise and personal circumstances. The key noise metrics were perceived performance, ability to work, well-being and stress plus three noise indices: concentration, distraction and speech interference.

The survey revealed that personality type does affect noise perception, in particular extroversion and neuroticism. Perceived control, screening ability, age, workplace, design and focused work are also factors. Personal variables accounted for 25 per cent of the variance in the ability to carry out work, and for 40 per cent of the variance in concentration and speech interference.

Whilst statistically significant differences were found for most of the psychological and personal variables, the size of effect was smaller than anticipated. This is likely because the survey was carried out across a range or workplaces, rather than in a laboratory, with a number of uncontrolled extraneous factors.

The research has resulted in the development of a design guidance document for controlling noise distractions based on more psychoacoustic, people-centred, principles than purely physical ones.

Most acoustics research is conducted in the laboratory and focuses on the physical sound properties. This research took a psychoacoustic approach focusing more on psychological and personal factors, and was carried out in the real world.

The purpose of this paper is to produce a critical history of MP3 technology in an effort to show how its stature as the digital music format of choice had nothing to do with music or associated industries and that its configuration as a product to be bought and sold was unintended.

The approach is reminiscent of Michel Foucault's critical histories, which sought to problematise our current understanding of existing cultural arrangements by unearthing the conditions that made the production of knowledge and their accompanying artefacts possible.

The paper documents how MP3s emerged by outlining the conditions that made its production viable, showing how before MP3s were profiled as commodities to be bought and sold online, the composite of technologies making up the standard MPEG1‐Layer III were objects of knowledge within the fields of electrical engineering and psychoacoustics, and later a process of compression used mainly by audio broadcasting professionals. The paper concludes by examining MPEG1‐Layer III's reconstitution as MP3: its formal configuration and valuation, first as a license for the broadcasting industry to compress sound and then as a “free‐ware” application distributed online.

The paper problematises the taken for granted status of commodities, in this case, MP3s, as digital music to be bought and sold, by revealing how they emerged. At a more parochial level, it produces a competing history of MP3 technology which until now has not been told.

Road accidents, an inadvertent mishap can be detected automatically and alerts sent instantly with the collaboration of image processing techniques and on-road video surveillance systems. However, to rely exclusively on visual information especially under adverse conditions like night times, dark areas and unfavourable weather conditions such as snowfall, rain, and fog which result in faint visibility lead to incertitude. The main goal of the proposed work is certainty of accident occurrence.

The authors of this work propose a method for detecting road accidents by analyzing audio signals to identify hazardous situations such as tire skidding and car crashes. The motive of this project is to build a simple and complete audio event detection system using signal feature extraction methods to improve its detection accuracy. The experimental analysis is carried out on a publicly available real time data-set consisting of audio samples like car crashes and tire skidding. The Temporal features of the recorded audio signal like Energy Volume Zero Crossing Rate 28ZCR2529 and the Spectral features like Spectral Centroid Spectral Spread Spectral Roll of factor Spectral Flux the Psychoacoustic features Energy Sub Bands ratio and Gammatonegram are computed. The extracted features are pre-processed and trained and tested using Support Vector Machine (SVM) and K-nearest neighborhood (KNN) classification algorithms for exact prediction of the accident occurrence for various SNR ranges. The combination of Gammatonegram with Temporal and Spectral features of the validates to be superior compared to the existing detection techniques.

Temporal, Spectral, Psychoacoustic features, gammetonegram of the recorded audio signal are extracted. A High level vector is generated based on centroid and the extracted features are classified with the help of machine learning algorithms like SVM, KNN and DT. The audio samples collected have varied SNR ranges and the accuracy of the classification algorithms is thoroughly tested.

Denoising of the audio samples for perfect feature extraction was a tedious chore.

The existing literature cites extraction of Temporal and Spectral features and then the application of classification algorithms. For perfect classification, the authors have chosen to construct a high level vector from all the four extracted Temporal, Spectral, Psycho acoustic and Gammetonegram features. The classification algorithms are employed on samples collected at varied SNR ranges.

The purpose of this paper is to present a system for customized binaural audio delivery based on the extraction of relevant features from a 2-D representation of the listener’s pinna.

The most significant pinna contours are extracted by means of multi-flash imaging, and they provide values for the parameters of a structural head-related transfer function (HRTF) model. The HRTF model spatializes a given sound file according to the listener’s head orientation, tracked by sensor-equipped headphones, with respect to the virtual sound source.

A preliminary localization test shows that the model is able to statically render the elevation of a virtual sound source better than non-individual HRTFs.

Results encourage a deeper analysis of the psychoacoustic impact that the individualized HRTF model has on perceived elevation of virtual sound sources.

The model has low complexity and is suitable for implementation on mobile devices. The resulting hardware/software package will hopefully allow an easy and low-tech fruition of custom spatial audio to any user.

The authors show that custom binaural audio can be successfully deployed without the need of cumbersome subjective measurements.

The purpose of this study is to answer the questions: Can students discern the difference between oral histories digitized at archival quality (96 kHz/24-bit) versus CD-quality (44.1 kHz/16-bit)? and How important do they believe this difference is? Digitization of analog audio recordings has become the recommended best practice in preserving and making available oral histories. Additionally, well-accepted standards in performing this work are available. However, there is relatively little research that addresses if individuals can hear a qualitative difference in recordings made with best practices versus those that have not.

In all, 53 individuals participated in the study, where they listened to three sets of oral histories and had to decide which was the archival-quality recording versus the CD-quality recording and mark their answer on a survey.

Students could discern less than half of the time on average which was the archival quality versus the CD-quality recording. Further, after listening to the differences, they most often indicated the difference was “a little bit important”.

This research does not suggest that archivists abandon well-established sound digitization practices that produce results that audio archivists (and those able to hear fine-grain audio differences) find superior. Rather, it does imply that additional work may be needed to train listeners to discern these fine-grain differences, and appreciate the highest-fidelity replication of original audio recordings.

This research addresses a gap in the literature by connecting audio digitization practices to its impact on listener perception.

Comorbidity of attention deficit hyperactivity disorder (ADHD) and reading disabilities (RD) is greater than what would occur by chance. Considering the well-documented adverse impact of both ADHD and RD on development, the presence of both conditions may lead to particularly poor outcomes for affected people. This chapter, which reviews 43 research studies carried out in the last decade that have focused on the link between ADHD and RD, is divided into two broad nuclei of contents. First, studies are described that contribute information about characteristics of the comorbid phenotype. Second, studies related to procedures directed toward evaluation and intervention in this problem are analyzed. The review carried out does not make it possible to extract definitive results on the exact nature of ADHD and RD comorbidity or, even less, reach conclusions about its causes. However, the literature-based evidence shows a cognitive profile of ADHD+RD characterized by failure of various functions that can produce more severe functional deficits and worse neuropsychological, academic, and behavioral outcomes. Furthermore, the analysis of the set of results from the studies shows a limited efficacy of pharmacological and psychopedagogical treatments, and highlights the need for continued research on this topic. From a clinical and educational standpoint, the conclusions derived from this review underline the importance of performing an exhaustive evaluation of children and adolescents with symptoms of ADHD and/or RD, in order to be able to plan interventions with greater possibilities of success in each case.

This study aims to explore the opportunities offered by interactive and situated learning (e-learning and m-learning) in support of education for sustainability in disciplines of the built environment.

The paper illustrates the development of an online portal and a mobile app aimed at promoting students’ motivation and engagement with sustainability in design, and discusses the outcomes of their testing, investigating users’ acceptance, comparing academic results and analysing feedback.

The findings add empirical evidence to the view that information and communication technology-enhanced pedagogies can substantially contribute to the agenda of sustainability in higher education, primarily due to their affordance of interactive communication and contextualisation of knowledge, while guaranteeing flexible time and pace of learning.

The study solely focused on the development and testing of e-learning and m-learning tools to foster students’ competence of sustainability in design studio work. The tools trialled were mostly at their prototypical stage and their testing included a relatively short-term evaluation and a narrow, self-selected, user base. However, the approach and findings are felt to be applicable to a much wider range of educational contexts.

Interactive and situated pedagogical methods and tools have the potential to prompt a departure from transmissive educational models, encompassing at once theoretical, experiential and analytic learning processes. This is of value to education for sustainability in disciplines of the built environment due to the requirement to holistically consolidate multi-/inter-/trans-disciplinary knowledge into a coherent design whole.

Sleep apps installed on smartphones are increasingly being used to help people overcome sleep problems. The purpose of this chapter is to identify the discourses that underpin discursive constructions of the potential sleep app user in sleep app marketing communication. According to critical marketing theory, discursive constructions of the potential consumer in marketing communication promote the potential consumer’s identification and alignment, priming the potential consumer to consider positively the product being marketed. In that sense, marketing (of sleep apps, or indeed anything) is culturally significant, as it provides templates for forms of identity, and affects the meanings and objects that circulate within a culture.

A data set consisting of the promotional material that was used to market acclaimed sleep apps was analysed using Foucauldian discourse analysis (FDA). The following discourses were identified in the data: disempowerment, pathologisation, ignorance, behaviourism, responsibilisation, mindfulness, seduction, convenience or common sense, empowerment and individualisation. These discourses indicate how sleep apps are legitimised as technical appendages to be installed into people’s phones and integrated into their lives. They also underpin the discursive identities that summon potential consumers into alignment. This chapter contributes to our understandings of the discursive mechanisms that lie behind the growing uptake of sleep apps. It also demonstrates the value of combining discourse analysis with relevant critical theory to gain insights into the emerging phenomenon of app culture.

Physical environments, especially the sound environments of ILSs on a university campus, have become increasingly important in satisfying the diverse needs of students. Poor sound environments are widely acknowledged to lead to inefficient and underutilised spaces and to negatively influence students' learning outcomes. This study proposes two hypotheses to explore whether students' sound environment perceptions are related to their individual characteristics and whether students' preferences for the type of ILS are related to their sound environment sensitivities.

An investigation through a questionnaire survey has been conducted on both students' individual characteristics affecting their sound environment perceptions in informal learning spaces (ILSs) of a university campus and their sensitivities to the sound environments in ILSs affecting their preferences for the type of ILSs.

The research findings indicate that students' sound environment perceptions are associated with some of their individual characteristics. In addition, the results show that students' sound environment sensitivities affect their preferences for the type of ILS they occupy.

This study could help architects and managers of university learning spaces to provide better sound environments for students, thereby improving their learning outcomes. The article contributes valuable insights into the correlation between students' individual characteristics, sound environment perceptions and preferences for ILSs. The research findings add to the existing knowledge in this field and offer practical implications for enhancing design and management of university learning environments.

The general attitude of the ancient theatre conservation strategies and policies is still concerned primarily with their architectural physical appearance without considering their authentic scientific acoustical qualities. The paper attempts to illustrate and discuss how to enhance their acoustic heritage to arouse the audience's interest and needs. Thus, supporting their reconstruction based on recent acoustical research and community needs-related concerns and opportunities for ancient theatre's modern use.

It is based on reviewing the main issues related to reconstruction in the international charters and conventions and how to infuse ancient theatres with their full role. It discusses the dilemma and debates regarding the theatre stage wall, colonnade (portico) restoration and anastylosis. Is it sufficient enough to recover the theatre sound volume? Or to rethink for full physical reconstructions of these missing related acoustical theatre architectural elements to their original level and layout as in ancient times in parallel to their virtual reconstruction?

The cultural significance of the authentic theatre's acoustical qualities needs to reform the conservation strategies and policies for a more flexible and resilient approach. It should be postulated, re-examined and advocated parallel to their 3D virtual reconstruction in the related international charters and conventions.

The paper's implications are not immediate; it is far-reaching. It suggests the importance of acoustics in analysing historic theatre performance venues and reforming conservation strategies and approaches. This issue is especially critical for architects, conservators, the heritage community and the public audience.

Recommendations are made for potential bold reconstruction actions that may be taken to achieve further sustainability, comfort, and permeability in modern theatre-use performances. Their physical reconstruction for improving the performance of contemporary theatre use regarding retaining the acoustic cultural significance should be more flexible and resilient in the charters.
