| Room Size | Recommended RT₆₀ | |-----------|------------------| | Up to 300 seats | 0.6–0.8 seconds | | Larger volumes | Up to 0.9 seconds (with arrayed reinforcement) | | Video-conference-enabled spaces | ≤ 0.5–0.6 seconds |
Lighting in a lecture theatre must serve multiple, often competing, purposes: enabling note-taking, supporting projected presentations, and ensuring safe entry and exit.
Background noise from HVAC systems and external corridors must be strictly minimized.
Modern standards mandate that lecture theatres are inclusive: lecture theatre design standards pdf

Maximising room capacity must never come at the expense of student comfort or physical well-being during long lectures. Spatial Allowances
To recap, here is a handy reference of the most critical documents mentioned throughout this guide. Spatial Allowances To recap, here is a handy
Designers use a mix of absorptive materials on the back wall (to prevent echoes) and reflective materials on the ceiling above the speaker to help project their voice naturally to the back of the room. 3. Visual Standards and Sightlines

Contemporary seating must accommodate a wider range of body sizes than older standards anticipated. Anthropometric data has shifted significantly in recent decades—women are now taller and heavier on average than in the 1920s. As a result, modern guidelines recommend:
The preferred minimum width for lecture hall aisles is 48 inches (approximately 1,220 mm). Aisle designs must accommodate:
Pre-programmed lighting scenes must allow the audience area to dim while maintaining targeted task lighting on desktops, ensuring screens remain glare-free. Power Infrastructure
Reverberation time is the duration it takes for sound to decay by 60 dB after the source stops. For lecture theatres and multipurpose halls where speech intelligibility is paramount, reverberation times should be kept relatively short:
