Government (US Access Board)

Summary

The historical explanation for replacing the ADA receiver requirement of a flat 4% of seating with a sliding scale.

Key findings

  • The discussion of section 219.3 says the advisory committee recommended a sliding scale based on actual and anecdotal evidence that the existing 4% requirement exceeded demand, especially in large facilities.
  • The proposal retained approximately 4% provision through 500 seats and reduced provision for larger seating capacities.
  • The proposal added a hearing-aid-compatible share of 25% of receivers, with a minimum of two.
  • The preceding discussion notes separate Department of Justice obligations to provide auxiliary aids where needed for effective communication.

Limits

A historical proposal, not the current design standard. The cited discussion supplies no underlying venue sample, lending records or hearing-loss prevalence study for its actual and anecdotal evidence. Its summary percentages should not replace the incremental calculation in the adopted Table 219.3.
