Report No.: 12124122-S2V2 Issue Date: 8/14/2018 5. Test Procedure ANSI C63.19-2011, Section 7 This document describes the procedures used to measure the ABM (T-Coil) performance of the WD. In addition to measuring the absolute signal levels, the A-weighted magnitude of the unintended signal shall also be determined. In order to assure that the required signal quality is measured, the measurement of the intended signal and the measurement of the unintended signal must be made at the same location for all measurement positions. In addition, the RF field strength at each measurement location must be at or below that required for the assigned category. Measurements shall not include undesired properties from the WD’s RF field; therefore, use of a coaxial connection to a base station simulator or non-radiating load may be necessary. However, even then with a coaxial connection to a base station simulator or non-radiating load there may still be RF leakage from the WD, which may interfere with the desired measurement. Pre-measurement checks should be made to avoid this possibility. All measurements shall be done with the WD operating on battery power with an appropriate normal speech audio signal input level given in Table 7.1. If the device display can be turned off during a phone call then that may be done during the measurement as well. Measurements shall be performed at two locations specified in A.3, with the correct probe orientation for a particular location, in a multistage sequence by first measuring the field intensity of the desired T-Coil signal (ABM1) that is useful to a hearing aid T-Coil. The undesired magnetic components (ABM2) must be measured at the same location as the desired ABM or T-Coil signal (ABM1), and the ratio of desired to undesired ABM signals must be calculated. For the perpendicular field location, only the ABM1 frequency response shall be determined in a third measurement stage. The flow chart in Figure 7.3 illustrates this three-stage, two orientation process. The following steps summarize the basic test flow for determining ABM1 1 and ABM22. These steps assume that a sine wave or narrowband 1/3 octave signal can be used for the measurement of ABM1. a. A validation of the test setup and instrumentation may be performed using a TMFS or Helmholtz coil. Measure the emissions and confirm that they are within the specified tolerance. b. Position the WD in the test setup and connect the WD RF connector to a base station simulator or a non- radiating load as shown in Figure 7.1 or Figure 7.2. Confirm that equipment that requires calibration has been calibrated, and that the noise level meets the requirements given in 7.3.1. c. The drive level to the WD is set such that the reference input level specified in Table 7.1 is input to the base station simulator (or manufacturer’s test mode equivalent) in the 1 kHz, 1/3 octave band. This drive level shall be used for the T-Coil signal test (ABM1) at f = 1 kHz. Either a sine wave at 1025 Hz or a voice- like signal, band-limited to the 1 kHz 1/3 octave, as defined in 7.4.2, shall be used for the reference audio signal. If interference is found at 1025 Hz an alternative nearby reference audio signal frequency may be used.46 The same drive level will be used for the ABM1 frequency response measurements at each 1/3 octave band center frequency. The WD volume control may be set at any level up to maximum, provided that a signal at any frequency at maximum modulation would not result in clipping or signal overload. d. Determine the magnetic measurement locations for the WD device (A.3), if not already specified by the manufacturer, as described in 7.4.4.1.1 and 7.4.4.2. 1 Audio Band Magnetic signal - desired (ABM1): Measured quantity of the desired magnetic signal 2 Audio Band Magnetic signal - undesired (ABM2): Measured quantity of the undesired magnetic signal, such as interference from battery current and similar non-signal elements.

Report No.: 12124122-S2V2 Issue Date: 8/14/2018 e. At each measurement location, measure and record the desired T-Coil magnetic signals (ABM1 at fi) as described in 7.4.4.2 in each individual ISO 266-1975 R10 standard 1/3 octave band. The desired audio band input frequency (fi) shall be centered in each 1/3 octave band maintaining the same drive level as determined in item c) and the reading taken for that band. Equivalent methods of determining the frequency response may also be employed, such as fast Fourier transform (FFT) analysis using noise excitation or input–output comparison using simulated speech. The full-band integrated or half-band integrated probe output, as specified in D.9, may be used, as long as the appropriate calibration curve is applied to the measured result, so as to yield an accurate measurement of the field magnitude. (The resulting measurement shall be an accurate measurement in dB A/m.) All measurements of the desired signal shall be shown to be of the desired signal and not of an undesired signal. This may be shown by turning the desired signal ON and OFF with the probe measuring the same location. If the scanning method is used the scans shall show that all measurement points selected for the ABM1 measurement meet the ambient and test system noise criteria in 7.3.1. f. At the measurement location for each orientation, measure and record the undesired broadband audio magnetic signal (ABM2) as specified in 7.4.4.4 with no audio signal applied (or digital zero applied, if appropriate) using A-weighting and the half-band integrator. Calculate the ratio of the desired to undesired signal strength (i.e., signal quality). g. Obtain the data from the postprocessor, SEMCAD, and determine the category that properly classifies the signal quality based on Table 8.5.

Report No.: 12124122-S2V2 Issue Date: 8/14/2018 5.1. Over the Top (OTT) The test procedure for OTT testing is identical to the section above, except for how the signal is sent to the DUT, as outlined in the diagram below. The AMMI is connected to an external ADC (Analog to Digital Converter) and the ADC is connected to the iMac via USB. The iMac is connected to the Internet via Ethernet and the DUT is connected to the Internet via Wi-Fi. Using the DUT’s OTT application, a VoIP call is established with the iMac. The test signal is sent from the DASY5 PC to the AMMI, from the AMMI to the ADC, from the ADC to the iMac, and finally to the DUT. To exercise the license antenna, the DUT was simultaneously connected to an external AP and to a mobile base station. This is essentially the manufacturer’s test mode method (C63.19 2007 §6.2.3) but with the audio wired signal injection replaced by the Wi-Fi connection.

Audio Level and Gain Measurements CDMA No correction gain factors were measured for CDMA due to the Rohde & Schwarz CMW500, hosting a calibrated audio board. The gains used to measure CDMA are set to 100. W-CDMA/GSM No correction gain factors were measured for W-CDMA/GSM due to the Rohde & Schwarz CMW500, hosting a calibrated audio board. The gains used to measure W-CDMA/GSM are set to 100. VoLTE No correction gain factors were measured for VoLTE due to the Rohde & Schwarz CMW500, hosting a calibrated audio board. The gains used to measure VoLTE are set to100. The following software/firmware was used to simulate the VoLTE server for testing: Firmware License Keys Software Name KS500 LTE FDD R8 SIG BASIC V3.7.30 for LTE KS550 LTE TDD R8 SIG BASIC KA100 IP APPL ENABLING IPv4 KA150 IP APPL ENABLING IPv6 V3.7.20 for Audio KAA20 IP APPL IMS BASIC KM050 DATA APPL MEAS KS104 EVS SPEECH CODEC VoWi-Fi No correction gain factors were measured for VoWi-Fi due to the Rohde & Schwarz CMW500, hosting a calibrated audio board.

The results below are based on a reference input level of -20 dBm0. Granted, the C63.19-2011 interpretation for T-coil audio levels for LTE states that an input reference level of -16 dBm0 should be used, we, the test lab, opted for -20 dBm0 for LTE due to it being a more conservative input reference level. The adjusted gain measurements are based on an external Analogue to Digital Converter (ADC), where the signal is sent from the AMMI to the ADC, then to the DUT via Wi-Fi. To calibrate the ADC, three .wav audio files (sine wave, 1 kHz voice, and 300 to 3 kHz voice) are sent from the DASY5 PC to the AMMI, then to the ADC. The Helmholtz resonator measures the field strength, which represents the AMMI to ADC input sensitivity. After determining the input sensitivity, the adjusted linear gain values can then be calculated.

Report No.: 12124122-S2V2 Issue Date: 8/14/2018 7. T-coil Measurement Criteria 7.1. Frequency Response The frequency response of the axial component of the magnetic field, measured in 1/3 octave bands, shall follow the response curve, over the frequency range 300 Hz to 3000 Hz. Figure 8.1 and Figure 8.2 provide the boundaries for the specified frequency. These response curves are for true field strength measurements of the T-Coil signal. Thus the 6 dB/octave probe response has been corrected from the raw readings. Page 11 of 24 UL Verification Services Inc. Doc.

Report No.: 12124122-S2V2 Issue Date: 8/14/2018 7.2. Signal to Noise This specifies the signal-to-noise quality requirement for the intended T-Coil signal from a WD. The worst signal to noise of the two T-Coil signal measurements, as determined in Clause 7, shall be used to determine the T-Coil mode category per Table 8.5. Only the RF immunity of the hearing aid is measured in T-Coil mode. It is assumed that a hearing aid can have no immunity to an interference signal in the audio band, which is the intended reception band for this mode. So, the only criterion that can be measured is the RF immunity in T-Coil Mode. This is measured using the same procedure as for the audio coupling mode and at the same levels as specified in 6.4.

Report No.: 12124122-S2V2 Issue Date: 8/14/2018 9.2. Codec Investigation An investigation between the various codec configurations (Low/Mid/High bit rates for Narrowband, Wideband, and EVS) and specific parameters are documented (ABM1, ABM2, S+N/N, frequency response) to determine the worst-case bit rates for each voice service type. The table below compares the varying codec configurations. A full codec investigation was performed on one LTE FDD and one LTE TDD band; another full codec investigation was performed on one W-CDMA band. Spot checks were then performed on the worst case bit rate from Narrowband, Wideband, and EVS to confirm that there were minimal variations between frequencies/bands. The highlighted results below were determined to be the worst case codec configuration(s) for LTE and W-CDMA.
