CAN-ASC-2.5/ICC A118 Acoustics in the Built Environment

There are common areas where people with disabilities may experience acoustics-related barriers to accessibility. These include, but are not limited to:

• Types of noise
• Sound level, reverberation time, sound absorption and transmission
• Noise levels from:
  • internal sources, such as equipment in the room, reverberation, and echo; and
  • external sources, such as impact noise, environmental noise, and a building’s heating and cooling equipment.
• Acoustics of specific spaces, such as workspaces, common areas, training spaces, and service counters
• Assistive technologies, including assistive listening systems and captioning systems, and the interoperability of these devices with personal technologies

• The standards development process started in summer 2022.
• The public review period is scheduled to start in fall 2025.
• The publication of the final standard is expected in fall 2026.
