The index depends on both reverberation and the signal-to-noise ratio: turning up the volume does not compensate for a reverberant room.&#13;\n<\/li>\n\n\n\n<li>A teacher moves between rooms several times a day. Standardizing interfaces from one room to the next weighs more on real-world use than the feature set of any individual device.&#13;\n<\/li>\n\n\n\n<li>A school estate is sized over ten years: software lifecycle, remote monitoring and maintenance are decided at the point of purchase.&#13;\n<\/li>\n<\/ul>\n\n<p>The connected classroom is no longer an experiment. Institutions now equip dozens of rooms at a time, with everything that implies: consistency between spaces, operating budget, staff training and equipment service life. The technical decisions taken at tender stage either cost or pay off over a decade. Here are the trade-offs that shape these projects.&#13;\n&#13;\n<\/p>\n\n<p><\/p>\n\n<h2 class=\"wp-block-heading\" id=\"h-un-cadre-pedagogique-qui-a-change-d-echelle\">A pedagogical framework that has changed scale<\/h2>\n\n<p>\u00a0<br\/><br\/>The Swiss context has moved quickly. The CIIP adopted an action plan for digital education, and the\u00a0<strong>Plan d&#8217;\u00e9tudes romand, the shared curriculum framework applied across several Swiss cantons, incorporated a digital education component in 2021<\/strong>, built around three strands: the use of digital tools, an introduction to computer science, and media literacy.<\/p>\n\n<p>\u00a0<br\/><br\/>The material consequence is straightforward.\u00a0<strong>A competence prescribed in the curriculum can no longer rest on a handful of equipped rooms<\/strong>: it calls for a consistent, available and maintained estate across all teaching spaces. Cantons have launched multi-year deployment programmes accordingly, and upper-secondary and tertiary institutions have followed the same movement.<\/p>\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"446\" height=\"363\" src=\"https:\/\/hi-technologies.ch\/app\/uploads\/2025\/11\/Salle-de-classe-Samsung-et-Logitech.jpg\" alt=\"salle de classe connect&#xE9;e samsung\" class=\"wp-image-2564\" srcset=\"https:\/\/hi-technologies.ch\/app\/uploads\/2025\/11\/Salle-de-classe-Samsung-et-Logitech.jpg 446w, https:\/\/hi-technologies.ch\/app\/uploads\/2025\/11\/Salle-de-classe-Samsung-et-Logitech-300x244.jpg 300w\" sizes=\"auto, (max-width: 446px) 100vw, 446px\" \/><\/figure>\n\n<h2 class=\"wp-block-heading\" id=\"h-le-premier-arbitrage-quel-affichage-pour-quelle-salle\">The first decision: which display for which room<\/h2>\n\n<p>Two architectures coexist, and the choice is not made at institution level but room by room.&#13;\n&#13;\n<\/p>\n\n<ul class=\"wp-block-list\">\n<li><ul>&#13;\n \t<li><strong>The interactive display<\/strong>\u00a0brings panel, touch layer and software together in a single device.

First the diagonal:\u00a0<strong>it is calculated from the distance of the back row and the nature of the content projected<\/strong>, an exercise we set out in our article on\u00a0<a href=\"https:\/\/hi-technologies.ch\/en\/what-screen-size-for-your-meeting-room\/\">the right screen size for a meeting room<\/a>. A page of textbook text or a table of data does not call for the same image as a slide of titles.<\/p>\n\n<p>\u00a0<br\/><br\/>Then the vocabulary of the specification. Interactive whiteboard, interactive display and touch screen describe different architectures, with distinct installation costs and maintenance plans: we devoted an article to the\u00a0<a href=\"https:\/\/hi-technologies.ch\/en\/interactive-whiteboard-vs-touch-screen\/\">differences between an interactive whiteboard and a touch screen<\/a>. Our\u00a0<a href=\"https:\/\/hi-technologies.ch\/en\/services\/education\/interactive-panels-led-walls-video-projection\/\">interactive panels, LED walls and video projection<\/a>\u00a0configurations always start from the geometry of the room.<\/p>\n\n<h2 class=\"wp-block-heading\" id=\"h-l-intelligibilite-le-critere-a-ne-pas-negliger\">Intelligibility, the criterion not to overlook<\/h2>\n\n<p>A classroom is a place where people speak all day long. Yet it is the display that captures the attention of specifications, while comprehension of speech directly conditions pupils&#8217; attention and teachers&#8217; vocal fatigue.&#13;\n&#13;\n<\/p>\n\n<p>The speech transmission index expresses the proportion of spoken information preserved between the person speaking and the person listening, on a single scale, and a simplified measurement method exists for use in the field.&#13;\n&#13;\n<\/p>\n\n<p>\u00a0<br\/><br\/>The main lesson is counterintuitive.\u00a0<strong>The index depends on two simultaneous factors: the reverberation of the room and the ratio between the level of the voice and that of the background noise.<\/strong>\u00a0In other words, turning up the volume of a sound system does not make up for a reverberant room: the useful signal and the parasitic reflections rise together.<\/p>\n\n<p>Two levers combine in practice:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><ul>&#13;\n \t<li><strong>Acoustic treatment<\/strong>\u00a0of the room, which reduces reverberation and benefits every use, including with no equipment at all.<\/li>&#13;\n<\/ul><\/li>\n\n\n\n<li><ul>&#13;\n \t<li><strong>Distributed sound reinforcement<\/strong>, with several low-power loudspeakers rather than a single source, paired with a microphone worn by the teacher.
