36 CFR Part 1194 - Proposed Information and Communication Technology (ICT) Standards and Guidelines NPRM - Preamble

410.2 Volume Gain (Section-by-Section Analysis)

This section proposes to require ICT with two-way communication to provide volume gain conforming to the FCC’s current regulation at 47 CFR 68.317, which establishes technical standards for volume control on analog and digital telephones to facilitate hearing aid compatibility. The proposed section would replace existing 508 Standards § 1194.23(f) and existing 255 Guidelines § 1193.43(e). The Advisory Committee recommended that the Board adopt the FCC’s volume gain requirements for landline ICT with two-way voice communication.

In July 2013, the FCC issued a request for comment on a petition for rulemaking filed by a telecommunications industry group requesting that the agency revise its hearing aid compatibility volume control gain requirements for analog and digital telephones.¹⁰ The Telecommunications Industry Association (TIA) petition urged the Commission to issue a notice of proposed rulemaking to, among other things, update its Part 68 rule to incorporate the most recent TIA standard for hearing aid compatibility volume control on telephones: ANSI/TIA-4965, Receive Volume Control Requirements for Digital and Analog Wireline Handset Terminals (2012). 28 FCC Rcd. at 10338-39. At present, the Commission’s regulation at § 68.317 sets forth separate requirements for analog and digital telephones based on speech amplification metrics known as “Receive Objective Loudness Rating” (ROLR). ANSI/TIA-4965, on the other hand, uses a new amplification metric—referred to as “conversational gain”—to establish requirements for both analog and digital telephones.

While the “conversational gain” method of measuring amplification for wireline phones in ANSI/TIA-4965 may hold promise, it would be premature for the Board to reference this standard unless and until it is adopted by the FCC. As the lead regulatory agency on hearing aid compatibility standards for wireline telephones, the FCC is in the best position to assess the technical merits, as well as costs and benefits, of referencing this new TIA standard in any subsequent revisions to its existing regulation in Part 68.

Question 26. The Board proposes to adopt 47 CFR 68.317, which is the FCC’s current regulatory standard addressing volume control for analog and digital telephones. In the future, should the FCC revise its regulation and incorporate by reference ANSI/TIA-4965 (or any other consensus standard) for wireline phones, the Board plans to update its regulations—as needed— to reflect revisions by the Commission. We seek comment on this proposed course of action.
