Reference standard: ANSI S12.60-2010 (USA) or BB93 (UK).
Internal finishes should provide both sound absorption (to reduce reverberation) and diffusion.
Ceiling height is among the most consequential decisions in lecture theatre design, affecting both sightline geometry and acoustic performance:

No seat should be placed outside a 45-degree angle from the edge of the primary display screen to avoid severe image distortion and neck strain.
Continuous fixed desks are highly preferred over swing-away tablets, providing a minimum depth of 300mm to accommodate both a laptop and a physical notebook. 3. Acoustic Engineering and Noise Control
For modern lecture halls, a background noise level of NC 25–30 is generally targeted, with quieter NC 20–25 desirable for video-conferencing-enabled spaces. If intrusive noise has an unusual character—such as a rumble from traffic or plant equipment—specifications should require noise levels 5 to 10 dB lower. Reference standard: ANSI S12
Floors are typically raked (sloped or tiered) to ensure clear views of the presenter and display. A suggested rake is roughly 150mm per row Faculty of Science and Technology | University of Macau 3. Lighting (CIBSE LG5)
