Among the choices listed, providing a fabric covering over the existing concrete walls would be the most effective design intervention to reduce reverberation times within the auditorium. Here's the breakdown:

The Problem: The feedback about echoes indicates that sound waves are persisting for too long within the space, creating overlapping sound reflections that interfere with clarity and comprehension.

Reverberation and Sound Absorption: Reverberation time is directly influenced by how much sound is absorbed or reflected by surfaces within a space. Hard, reflective materials like concrete prolong reverberation times.

Why Fabric Walls Are Most Effective: Adding fabric wall coverings introduces a significant amount of sound-absorbing material directly where it's most needed. This will drastically reduce sound reflections and shorten reverberation times, helping mitigate the echo problem.

Tier 3 pesticides are the least hazardous pesticides according to the City of San Francisco Pesticide Hazard Screening Protocol, which is one of the reference standards used by WELL v2 to evaluate pesticide safety. WELL v2 requires projects to use outdoor pesticides with a Hazard Tier ranking of 3, except in cases of emergency, and to implement an Integrated Pest Management plan to minimize pesticide use.

For visual balance in a workspace, ensuring an illuminance uniformity ratio of at least 0.4 on any horizontal task plane within a space is essential. This requirement helps in creating a visually comfortable environment by reducing fluctuations in light levels that can lead to eye fatigue and visual discomfort​​.
