Common acoustic mistakes in lecture halls

The errors we see most often in lecture halls, and how to avoid them.

2 minute read · Updated Nov 2026

Most disappointing results in lecture halls come from a few predictable mistakes.

  1. Deadening the front of the room
  2. Leaving a concave rear wall bare
  3. Buying by the panel instead of by the absorption the room needs.
  4. Confusing absorption with soundproofing.

Avoid all of these by starting with the panel count and the placement guide.
