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…

General calibration information Date 2023.12.06 Test Laboratory ShenZhen Morlab Communications Technology Co., Ltd. Antenna serial No. D2450V2-SN: 805 Antenna Parameters with Head TSL Impedance, transformed to feed point 53.394Ω+0.632jΩ Return Loss -29.528dB General Antenna Parameters and Design Electrical Delay (one direction) 1.276 ns After long term use with 100W radiated power，only a slight warming of the dipole near the feed point can be measured The dipole is made of standard semirigid coaxial cable. The center conductor of the feeding line is directly connected to the second arm of the dipole. The antenna is therefore short-circuited for DC-signals. On some of the dipoles, small end caps are added to the dipole arms in order to improve matching when loaded according to the position as explained in the "Measurement Conditions" paragraph. The SAR data are not affected by this change. The overall dipole length is still according to the Standard No excessive force must be applied to the dipole arm， because they might bend or the soldered connections near the feed point may be damaged .
