“…Acoustics must also be considered to control reverberation time [70], and noises from outside [71] and inside the classroom [72]; to avoid echo effects [73]; and to improve sound quality in general [74]. These aspects directly affect the student learning process.…”

“…In relation to the environmental conditions, lighting could be smart, adapted to different spaces and tasks at the same time and in real time [78,79]. Additionally, acoustics can be smart, adapted to spaces that need to mix silence, debates, discussions, brainstorming and oral presentations [70][71][72][73][74]77,81]. The colours of the learning spaces have to be adapted to student needs according the type of activity, at the same time that Smart walls permit students to write, present and share ideas and knowledge [49,52].…”

The Smart Classroom as a Means to the Development of ESD Methodologies

Educational institutions are envisioned as principal agents for addressing the current sustainability challenge that society is facing. Education for Sustainable Development (ESD) is transformational and concerns learning content and outcomes, pedagogy and the learning environment in itself. ESD entails rethinking the learning environment (physical and virtual) in line with sustainable development, which implies classrooms' transformation towards learner engagement, formative assessments and active methodologies. This paper responds to this need through exploring the relationship between Smart Classrooms and four widely used ESD methodologies (project or problem-based learning, case study, simulation and cooperative inquiry), identifying how the dimensions and categories of the characteristics of Smart Classrooms can contribute and lead to the implementation of ESD methodologies in real teaching practice in an effective way. The method used in this study consisted of a literature review of both theoretical frameworks separately, ESD and Smart Classrooms, and a subsequent expert analysis to identify the interrelation between both. The Smart Classroom shows a high level of adequacy for using problem and project-based learning, case study and cooperative inquiry methods because of its characteristics in terms of technology developments, environmental conditions and processes. Simulation is the ESD methodology with the lowest level of adequacy in a Smart Classroom, because it is primarily held online rather than through face-to-face teaching. Smart Education facilitates the putting in practice of ESD processes as it enables the creation of intelligent, sustainable, resource-efficient, personalised and adaptive learning environments. Further empirical research is needed to explore the influence that the Smart Classroom has in enabling ESD processes and practices, and to identify students' and teachers' needs at different education levels. Additionally, teacher training programmes focused on the correct use of Smart Classrooms and on the digital competence of teachers are critical to its successful implementation.

“…It can be considered that the noise coming from outdoors, when considered as a equivalent sound level, as required in the evaluation of the STI, is usually lower than the noise produced inside the office and also in the cases of noisy outdoor environments, as shown in previous studies of the author [42]. The effect of short duration noise events coming from outdoors (such as sirens, passing of very noise vehicles and others) could reduce the intelligibility inside the office when the sound insulation given by the façade is low [18]. Anyway, these short duration noise events are not properly evaluated in the analysis of the Speech Transmission Index, since the study of this parameter requires the use of a continuous and uniform background noise.…”

Acoustic Issues in Open Plan Offices: A Typological Analysis

This paper reports the acoustic issues of open plan office environments. According to a detailed research based on the scientific literature of the most suitable acoustic descriptors recommended for the open plan offices analysis, the main typological-functional configurations of these environments have been analyzed in order to identify six spatial typologies. The variation of acoustic parameters of these typologies has been evaluated by using a sound pyramid tracing software. The analysis procedure was calibrated in a case study of an office environment, where a measurement campaign was carried out. Results point out that the acoustic improvement of open plan offices can usually be achieved by introducing a sound absorbing false ceiling and dividing panels between working positions, but there are different issues depending on spatial geometries of the office. Better results are referred to office typologies characterized by reduced height and equal plan dimensions.

“…Secchi et al developed a method to estimate students' exposure to road traffic noise events [9] from data available on noise maps by the municipalities of metropolitan areas, using regression equations obtained between L Aeq and A-weighted maximum and statistical levels due to road traffic noise. The traffic noise of 28 urban streets was monitored during the opening period of Italian schools.…”
