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.

Sealing the HVAC ducts is a measure that can prevent air leakage and contamination from the ductwork, which can affect the indoor air quality and energy efficiency of the building. According to the WELL v2 Feature Library, this measure is part of Feature 14: Air Sealing, which is applicable to the construction phase of the project. The construction phase is the stage when the building envelope and the mechanical systems are installed and tested, and when the duct sealing can be most effectively performed.

A building owner should use an air tightness test to assess the building envelope’s performance in regard to moisture protection. An air tightness test measures the rate of air leakage through the building envelope, which can indicate the potential for moisture infiltration and condensation. Moisture can enter buildings and building assemblies in four ways: bulk water, capillary water, air-transported moisture and vapor diffusion. Air-transported moisture is the most significant source of moisture problems in buildings, as it can carry large amounts of water vapor through small openings and gaps in the envelope. By conducting an air tightness test, the building owner can identify and seal any air leaks that could compromise the moisture protection of the building envelope.
