Federal Communications Commission DA 25-759 Before the Federal Communications Commission Washington, D.C. 20554 In the Matter of Achieving 100% Wireless Handset Model Hearing Aid Compatibility Amendment of the Commission’s Rules Governing Standards for Hearing Aid-Compatible Handsets ) ) ) ) ) ) ) WT Docket No. 23-388 WT Docket No. 20-3 ORDER Adopted: August 26, 2025 Released: August 26, 2025 By the Chief, Wireless Telecommunications Bureau: I. INTRODUCTION 1. We hereby extend the existing waiver of section 20.19(b) of the Commission’s rules to permit handset manufacturers to continue to use the temporary volume control standard to certify new handset models as hearing aid compatible. 1 We extend the waiver by two years with a new expiration date of September 29, 2027, unless a new volume control standard becomes effective through Commission action prior to this date. Under this two-year extension, new handset models may continue to be certified as hearing aid-compatible as long as the handset models meet the requirements of the temporary volume control standard as well as all other aspects of the 2019 American National Standards Institute (ANSI) Standard used to certify handset models as hearing aid compatible. 2 We also require CTIA, in coordination with the Telecommunications Industry Association (TIA), to file two progress reports updating us on the status of achieving the milestones set out in the TIA update that CTIA links to in its Petition for Extension of Waiver. 3 We take these steps to ensure that new handset models can continue to be certified as hearing aid compatible as well as to encourage the prompt development of a permanent volume control standard that the Commission can incorporate into its rules. II. BACKGROUND 2. In 2017 the Commission adopted a volume control requirement for certifying new handset models as hearing aid compatible. 4 While the Commission adopted a volume control 1 47 CFR § 20.19(b). 2 Amendment of the Commission’s Rules Governing Standards for Hearing Aid-Compatible Handsets, WT Docket No. 20-3, Order, 38 FCC Rcd 8636 (WTB Sept. 29, 2023) (adopting a temporary volume control standard) (HAC Waiver Order). 3 CTIA Petition for Extension of Waiver, WT Docket Nos. 23-388 and 20-3, at 3 & n.8. (filed July 2, 2025) (CTIA Petition), https://www.fcc.gov/ecfs/document/10702062626450/1. CTIA’s petition includes a link to a TIA status update on the development of a permanent volume control standard. This update includes a link to a more detailed TIA status update. 4 Amendment of the Commission’s Rules Governing Hearing Aid-Compatible Mobile Handsets, WT Docket No. 07- 250, Report and Order and Order on Reconsideration, 32 FCC Rcd 9063, 9073–74, para. 23 (2017). The Commission modified its wireless hearing aid compatibility rules by adopting a volume control requirement similar to the requirement for wireline phones and affirmed its belief that a volume control requirement that specifies certain levels of amplification as an element of hearing aid compatibility is just as necessary for wireless handsets as it is for (continued....) Federal Communications Commission DA 25-759 2 requirement, the Commission did not adopt a specific volume control standard. Instead, the Commission noted that an industry approved technical standard was nearing completion and, once the Commission adopted this standard into its rules, compliance with this standard would constitute compliance with the Commission’s new wireless volume control requirement. 5 3. In September 2019, the ANSI Committee filed a petition with the Commission asking the Commission to replace the existing 2011 ANSI Standard referenced in the Commission’s rules with the new 2019 ANSI Standard. 6 Like the 2011 ANSI standard, the 2019 ANSI Standard addresses acoustic and inductive coupling between wireless handset models and hearing aids. 7 The 2019 ANSI Standard, however, also includes the wireless volume control technical standard referenced by the Commission in 2017. 8 The 2019 ANSI standard specifically incorporates by reference the TIA 5050 Standard that addresses volume control requirements for wireless handset models. 9 In February 2021, as requested by ANSI and commenters, the Commission adopted the 2019 ANSI Standard for determining hearing aid compatibility. 10 After a two-year transition period, on June 5, 2023, the 2019 ANSI Standard was set to become the exclusive testing standard for determining hearing aid compatibility. 11 4. On December 16, 2022, the Alliance for Telecommunications Industry Solutions (ATIS) filed a petition for a limited, interim waiver of sections 20.19(b)(1) and (3) of the Commission rules to allow wireless handset models to satisfy a reduced volume control testing methodology—instead of the full ANSI/TIA Volume Control Standard incorporated into the 2019 ANSI Standard—in order to be certified as hearing aid compatible. 12 ATIS argued that the standard that ANSI asked the Commission to adopt was fundamentally flawed because it uses a pulsed-noise signal, which it claimed was insufficiently voice like to be compatible with many modern codecs. 13 5. On April 14, 2023, the Wireless Telecommunications Bureau (WTB) released an order extending the transition period for exclusive use of the 2019 ANSI Standard from June 5, 2023 to December 5, 2023. 14 WTB took this step to ensure that handset manufacturers could continue to certify (Continued from previous page) wireline phones in order to ensure the provision of effective telecommunication services for people with hearing loss.

Federal Communications CommissionDA 23-914 Before the Federal Communications Commission Washington, D.C. 20554 In the Matter of Amendment of the Commission’s Rules Governing Standards for Hearing Aid-Compatible Handsets ) ) ) ) WT Docket No. 20-3 ORDER Adopted: September 29, 2023Released: September 29, 2023 By the Chief, Wireless Telecommunications Bureau: I.INTRODUCTION 1.Today we grant a limited waiver of section 20.19(b)(1) and (b)(3) of the Commission’s wireless hearing aid compatibility rules with respect to the volume control technical standard that handset manufacturers use in part to certify handsets as hearing aid-compatible under the 2019 ANSI Standard. 1 Our action is prompted by a request filed by the Alliance for Telecommunications Industry Solutions (ATIS) seeking waiver of certain aspects of these rules. 2 Under the terms of the time-limited waiver we grant today, a handset may be certified as hearing aid-compatible under the 2019 ANSI Standard if it meets the volume control testing requirements described in this Order as well as all other aspects of the 2019 ANSI Standard. 2.Consistent with ATIS’s September 12, 2023, ex parte letter (ATIS Ex Parte Letter) and as a condition of this waiver, we require a handset to pass the conversational gain test at the 2 Newton (N) force level on all available narrowband and wideband codecs and air interface combinations. 3 With respect to the 8N force level test, we agree with the ATIS Ex Parte Letter that this test should be performed, and we waive the requirement that a handset achieve at least an 18 dB conversational gain. 4 This waiver is conditioned on manufacturers performing the 8N force level test using the same testing parameters that we are requiring for the 2N force level test and to place on the handset’s package label the resulting conversational gain (even if it is below 18 dB) in a manner consistent with our existing hearing aid compatibility labeling rules. 3.With respect to the related receive distortion and noise performance (distortion/noise) and receive acoustic frequency response performance (frequency response) tests, we agree with the ATIS Ex Parte Letter that handsets must pass testing using at least one narrowband and one wideband codec of the 1 The 2019 ANSI Standard refers to the technical document entitled Accredited Standards Committee C63®– Electromagnetic Compatibility, American National Standard Methods of Measurement of Compatibility Between Wireless Communications Devices and Hearing Aids, ANSI C63.19-2019 (approved Aug. 19, 2019) (2019 ANSI Standard). 2 Petition of ATIS on Behalf of the Covered Entities of the Hearing Aid Compatibility Task Force for Limited, Interim Waiver, WT Docket Nos. 15-285 and 20-3 (filed Dec. 16, 2022) (ATIS Waiver Petition). ATIS filed its waiver petition on behalf of all manufacturers and service providers subject to section 20.19(b)(1) and (b)(3) of the Commission’s wireless hearing aid compatibility rules. Id. at 1, 4. 3 Letter from Thomas Goode, General Counsel, ATIS, to Marlene H. Dortch, Secretary, FCC, WT Docket Nos. 15- 285 and 20-3, at 2 (filed Sept. 12, 2023) (ATIS Ex Parte Letter); see also ATIS Waiver Petition at 4, 12-13. Below we explain the conversational gain test. See infra para. 9. 4 ATIS Ex Parte Letter at 2. Originally, ATIS had proposed to waive the entire 8N force level test. ATIS Waiver Petition at 10-11, 13. Federal Communications CommissionDA 23-914 2 manufacturer’s choosing. 5 We also accept ATIS’s suggestion that at least one narrowband and one wideband codec must pass testing for distortion/noise and frequency response and tests will be limited to one bit rate and only with those air interfaces associated with the chosen codecs and that the other codecs used for conversational gain at the 2N and 8N force levels are not required to undergo the distortion/noise and frequency response tests. 6 Further, as detailed below, we accept ATIS’s suggested method to set the volume control setting for testing these other codecs for conversational gain. 7 4.By taking these steps, we ensure that when the exclusive use transition period ends on December 5, 2023, new handset models can be certified as hearing aid-compatible using the 2019 ANSI Standard as modified by the conditions established in this Order. 8 Our actions allow consumers with hearing loss who use hearing aids or cochlear implants to benefit from wider availability of handsets offering improved hearing aid compatibility under the 2019 ANSI Standard’s radio frequency (RF) interference and inductive coupling requirements. In addition, our approach gives consumers assurance that a handset’s amplifier/speaker combination will provide improved volume control functionality over narrowband and wideband modes of voice communications, and that consumers have the information that they need to make informed purchasing decisions. Our actions today will move us closer to the Commission’s goal of reaching 100% hearing aid compatibility for wireless handsets, while also creating a path forward for testing to ensure that handsets have volume control capabilities. 9 5.This waiver is effective immediately upon release of this Order so that manufacturers may afford the benefits of this relief to consumers with hearing loss as soon as feasible. In reliance upon ATIS’s representations that efforts are underway to expeditiously develop a new volume control standard through the TIA standards setting process, we limit this waiver to a two-year period. 10 During this waiver period, we will evaluate the effectiveness of the waiver standard in meeting the needs of consumers with hearing loss and take action where appropriate. We expect that a two-year time limitation for the waiver will encourage all interested parties to work together to rapidly develop an improved volume control standard that we can incorporate into our rules in the future. To ensure this outcome, we condition this waiver in part on ATIS filing a status lett…
