Sound systems
In lower secondary schools, upper secondary schools, vocational schools, as well as universities and universities of applied sciences, sound quality plays a critical role in teaching, informing and ensuring safety.
A properly designed sound system improves speech intelligibility in classrooms and lecture halls, simplifies day-to-day operations and supports smooth communication across the entire campus.
Hi Technologies supports educational institutions with professional audio solutions that are reliable, easy to use and tailored to learning environments across French-speaking Switzerland.
Sound environments designed for teaching needs
Audio requirements differ between a lower secondary classroom, an upper secondary lecture theatre, a university auditorium or an administrative building.
In every case, the goal remains the same: speech that is clear, intelligible and evenly distributed.
Hi Technologies delivers:
• even sound coverage, including in large rooms,
• high speech intelligibility, essential for learning,
• solutions tailored to hybrid teaching,
• robust installations designed for intensive use,
• simple interfaces for educational and technical staff,
• seamless integration with existing infrastructure.
Each project takes acoustics, architecture and academic use cases into account.
Hi Technologies designs Public Address systems perfectly suited to lower secondary schools, upper secondary schools and university campuses.
Our solutions ensure clear, effective and secure communication across all your facilities.
Public Address (PA) systems: inform, secure, broadcast
Public Address sound systems enable clear, consistent messaging across educational sites: school buildings, auditoriums, sports facilities, outdoor areas or entire campuses.
They are used for:
• daily announcements,
• administrative messages,
• multi-zone broadcasting,
• emergency and evacuation alerts,
• integration with security systems,
• coordinating events or student movements.
Key requirements for institutions:
✔ Intelligibility, even in noisy areas,
✔ Centralised, reliable control,
✔ Improved safety,
✔ Continuous operation,
✔ Coverage for one or multiple buildings.
Hi Technologies creates auditoriums that are highly intelligible, robust and aligned with the demands of modern education.
Each system is calibrated to deliver clear, natural sound, regardless of seating layout or room capacity.
Auditorium sound systems: audio for lectures, conferences and academic events
Lecture theatres and auditoriums play a central role in upper secondary education, training centres and higher education, hosting lectures, conferences, thesis defences and institutional events.
Our solutions include:
• sound reinforcement designed for large volumes,
• line-array systems for uniform coverage,
• professional microphones for lecturers, panels and audience,
• voice-optimised audio processing,
• compatibility with video capture and streaming,
• intuitive interfaces for teachers and technicians.
