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.
