INTRODUCTION
On July 10, 2003, the Federal Communications Commission (FCC) adopted new rules requiring wireless
manufacturers and service providers to provide digital wireless phones that are compatible with hearing
aids. The FCC has modified the exemption for wireless phones under the Hearing Aid Compatibility Act of
1998 (HAC Act) in WT Docket 01-309 RM-86581 to extend the benefits of wireless telecommunications to
individuals with hearing disabilities. These benefits encompass business, social and emergency
communications, which increase the value of the wireless network for everyone. An estimated more than
10% of the population in the United States show signs of hearing impairment and of that fraction, almost
80% use hearing aids. Approximately 500 million people worldwide and 30 million people in the United
States suffer from hearing loss.
Compatibility Tests Involved:
The standard calls for wireless communications devices to be measured for:
 RF Electric-field emissions
 T-coil mode, magnetic-signal strength in the audio band
 T-coil mode, magnetic-signal frequency response through the audio band
 T-coil mode, magnetic-signal and noise articulation index
The hearing aid must be measured for:
 RF immunity in microphone mode
 RF immunity in T-coil mode
In the following tests and results, this report includes the evaluation for a wireless communications
device.

LTE Band Selection
This device supports the following pair of LTE bands with similar frequencies: LTE B25 & B2, LTE B66 &
B4, AND B41 & B38. These pairs of LTE bands share the same transmission path and either have the
same target power or the smaller band has a lower target power. Since the supported frequency span for
the smaller LTE band is completely covered by the larger LTE bands, only the larger LTE bands (LTE
B25, B66, B41) were evaluated for hearing-aid compliance.

Signal Quality
The table below provides the signal quality requirement for the intended audio magnetic signal from a
wireless device. 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. The only criterion that can be measured is the RF immunity in
T-coil mode. This is measured using the same procedure as the audio coupling mode at the same
levels.
The signal quality of the axial and radial components of the magnetic field was used to determine the
T-coil mode category.

Figure 4-5 Magnetic Measurement Processing Steps
IV.
Test Procedure
1. Ambient Noise Check per C63.19 §7.3.1
a. Ambient interference was monitored using a Real-Time Analyzer between 100-10,000 Hz
with 1/3 octave filtering.
b. “A-weighting” and Half-Band Integration was applied to the measurements.
c. Since this measurement was measured in the same method as ABM2 measurements,
this level was verified to be more than 10 dB below the lowest measurement signal
(which is the highest ABM2 measurement for a T4 WD). Therefore the maximum noise
level for a T4 WD with an ABM1 = -18 dBA/m is:
-18 - 30 - 10= -58 dBA/m
2. Measurement System Validation(See Figure 4-1)
a. The measurement system including the probe, pre-amplifier and acquisition system were
validated as an entire system to ensure the reliability of test measurements.
b. ABM1 Validation
The magnetic field at the center of the Helmholtz coil is given by the equation (per
C63.19 Annex D.10.1):
N( )
NI
Hc =
r 1.25
r 1.253
Where Hc = magnetic field strength in amperes per meter
N = number of turns per coil
For the Helmholtz Coil, N=20; r=0.08m; R=10.2Ω and using V=18mV:
0.018
10
Hc =
= 0.316 A / m ≈ −10dB( A / m)
0.08 ⋅ 1.253
20 ⋅ (
Therefore a pure tone of 1kHz was applied into the coils such that 18mV was observed
across the resistor. The voltmeter used for measurement was verified to be capable of
measurements in the audio band range. This theoretically generates an expected field of
-10 dB(A/m) in the center of the Helmholtz coil which was used to validate the probe
measurement at -10dB(A/m). This was verified to be within ± 0.5 dB of the -10dB(A/m)
value (see Page 45).

Frequency Response Validation
The frequency response through the Helmholtz Coil was verified to be within 0.5 dB
relative to 1kHz, between 300 – 3000 Hz using the Normal signal as shown below:
Figure 4-6 Frequency Response Validation
d. ABM2 Measurement Validation
WD noise measurements are filtered with A-weighting and Half-Band Integration over a
frequency range of 100Hz – 10kHz to process ABM2 measurements. Below is the
verification of the system processing A-weighting and Half-Band integration between
system input to output within 0.5 dB of the theoretical result:

The ABM2 result is a power sum from 100Hz to 10kHz with half-band integration and Aweighting. To verify the power sum measurement, a power sum over the full band was
measured and verified to track with the source level (See Figure 4-8). Therefore the
setup in this step was used to verify the power sum post-processing for ABM2
measurements. See below block diagram:

4. Signal Quality Data Analysis
a. Narrow-band Magnetic Intensity
i. The standard specifies a 1kHz 1/3 octave band minimum field intensity for a sine
tone. The ABM1 measurements were evaluated at 1kHz with 1/3 octave band
filtering over an averaged period of 10 seconds.
b. Frequency Response
i. The appropriate frequency response curve was measured to curves in Figure 3-1
or Figure 3-2 between 300 – 3000 Hz using digital linear averaging (limit lines
chosen according to measurement found in step 4a). A linear average over 3x
the length of the artificial voice signal (3x sampling) was performed. A 10 second
delay was configured in the measurement process of the stimulus to ensure
handset vocoder latency effects and echo cancellation devices (if any) were
appropriately stabilized during measurements.
ii. The appropriate post-processing was applied according to the system processing
chain illustrated in Figure 4-6. All R10 frequencies were plotted with respect to
0dB at 1kHz value and aligned with respect to the EIA-504 mask.
iii. The margin is represented by the closest measured data point on the curve to
the EIA-504 limit lines, in dB.

Signal Quality Index
i. Ensuring the WD was at maximum RF power, maximum volume, backlight off,
display on, maximum contrast setting, keypad lights on (when possible) with no
audio signal through the vocoder, the WD was measured over at least 100 Hz –
10,000 Hz, maximized over 5 seconds with a 50ms sample time for the ABM2
measurement (5 second time period is used in noise measurements under
standards such as IEEE 269, etc.).
ii. After applying half-band integration and A-weighting to the result, a power sum
was applied over each 1/3 octave bandwidth frequency for an ABM2 value.
iii. This result was subtracted from the ABM1 result in step a, to obtain the Signal
Quality.

3. LTE TDD Uplink-Downlink Configuration Investigation for VoLTE over IMS
An investigation was performed to determine the worst-case Uplink-Downlink configuration for
VoLTE over IMS T-Coil testing.
Per 3GPP TS 36.211, the total frame length for each TDD radio frame of length Tf = 307200 · Ts
= 10 ms, where Ts is a number of time units equal to 1/(15000 x 2048) seconds. Additionally,
each radio frame consists of 10 subframes, each of length 30720 · Ts = 1 ms, and subframes can
be designated as uplink (U), downlink (D), or special subframe (S), depending on the UplinkDownlink configuration as indicated in Table 4.2-2 of 3GPP TS 36.211. In the transmission duty
factor calculation, the special subframe configuration with the shortest UpPTS duration within the
special subframe is used and will be applied for measurement. From 3GPP TS 36.211 Table 4.21, the shortest UpPTS is 2192 · Ts which occurs in the normal cyclic prefix and special subframe
configuration 4.
See table below outlining the calculated transmission duty cycles for each Uplink-Downlink
configuration:

I.
OTT VOIP TEST SYSTEM AND DUT CONFIGURATION
Test System Setup for OTT VoIP T-Coil Testing
1. OTT VoIP Application
Google Duo is a pre-installed application on the DUT which allows for VoIP calls in a held-to-ear
scenario. Duo uses the OPUS audio codec and supports a bitrate range of 6kb/s to 64kb/s. All air
interfaces capable of a data connection were evaluated with Google Duo.
2. Equipment Setup
A CMW500 callbox was used to perform OTT VoIP T-coil measurements. The Data Application
Unit (DAU) of the CMW500 was connected to the internet and allowed for an IP data connection
on the DUT. An auxiliary VoIP unit was used to initiate an OTT VoIP call to the DUT. The auxiliary
VoIP unit allowed for the configuration and monitoring of the OTT VoIP codec bitrate during a call.
Both high and low bitrate settings were evaluated in to determine the worst-case configuration.
3. Audio Level Settings
According to KDB 285076 D02, the average speech level of -20dBm0 shall be used for protocols
not specifically listed in Table 7.1 of ANSI C63.19-2011 or the ANSI C63.19-2011 VoLTE
interpretation3. The auxiliary VoIP unit allowed for monitoring the signal input level to ensure that
the settings for speech input and full scale levels resulted in the -20dBm0 speech input level to
the DUT for the OTT VoIP call.
II.
DUT Configuration for OTT VoIP T-Coil Testing
1. Codec Configuration
An investigation was performed for each applicable data mode to determine the audio codec
configuration to be used for testing. The 64kbps codec setting was used for the audio codec on
the auxiliary VoIP unit for OTT VoIP T-Coil testing. See below tables for comparisons between
codec data rates on all applicable data modes:

An investigation was performed on all applicable 802.11ax Resource Unit (RU) indexes to
determine the radio configuration to be used for testing. The data rate and modulation for each
bandwidth was chosen from the worst-case configuration of IEEE 802.11ax SU from Tables 7-10
and 7-11. See tables below for SNNR comparison between RU indexes in each 802.11ax
bandwidth:

Notes:
1. Test equipments are calibrated according to techniques outlined in NIS81, NIS3003 and NIST Tech Note 1297.
2. All equipments have traceability according to NIST. Measurement Uncertainties are defined in further detail in
NIS 81 and NIST Tech Note 1297 and UKAS M3003.
Measurement uncertainty reflects the quality and accuracy of a measured result as compared to the true
value. Such statements are generally required when stating results of measurements so that it is clear to
the intended audience that the results may differ when reproduced by different facilities. Measurement
results vary due to the measurement uncertainty of the instrumentation, measurement technique, and test
engineer. Most uncertainties are calculated using the tolerances of the instrumentation used in the
measurement, the measurement setup variability, and the technique used in performing the test. While
not generally included, the variability of the equipment under test also figures into the overall
measurement uncertainty. Another component of the overall uncertainty is based on the variability of
repeated measurements (so-called Type A uncertainty). This may mean that the Hearing Aid
compatibility tests may have to be repeated by taking down the test setup and resetting it up so that there
are a statistically significant number of repeat measurements to identify the measurement uncertainty. By
combining the repeat measurement results with that of the instrumentation chain using the technique
contained in NIS 81 and NIS 3003, the overall measurement uncertainty was estimated.

CONCLUSION
The measurements taken in accordance with the procedures provided in the CTIA Test Plan for Hearing
Aid Compatibility Rev 3.1, February 2017, indicate that the wireless communications device complies with
the HAC limits specified in the ANSI C63.19 Standard and FCC WT Docket No. 01-309 RM-8658. Precise
laboratory measures were taken to assure repeatability of the tests. The tested device complies with the
requirements in respect to all parameters specific to the test. The test results and statements relate only
to the item(s) tested.
The measurement system and techniques presented in this evaluation are proposed in the ANSI standard
as a means of best approximating wireless device compatibility with a hearing-aid. The literature is under
continual re-construction.
