  4. RF Audio Interference Level
  FCC wireless hearing aid compatibility rules ensure that consumers with hearing loss are able to access wireless
  communications services through a wide selection of handsets without experiencing disabling radio frequency (RF)
  interference or other technical obstacles.
  To define and measure the hearing aid compatibility of handsets, in CFR47 part 20.19 ANSI €C63.19 is referenced.
  A handset is considered hearing aid—compatible for acoustic coupling if it meets a rating of at least M3 under ANSI
  C63.19, and A handset is considered hearing aid compatible for inductive coupling if it meets a rating of at least T3.
  According to ANSI €63.19 2011 version, for acoustic coupling, the RF electric field emissions of wireless
  communication devices should be measured and rated according to the emission level as below.

                                                                    E—field emissions

Remark:
1. The air interface is exempted from testing by low power exemption that its average antenna input power plus its MIF is ≤17
    dBm, and is rated as M4.
2. The device have similar frequency in some LTE bands: LTE 38/41, since the supported frequency spans for the smaller LTE
    bands are completely cover by the larger LTE bands, therefore, only larger LTE bands were required to be tested for
    hearing-aid compliance.

  6.2 Data Storage and Evaluation

  The DASY software stores the assessed data from the data acquisition electronics as raw data (in microvolt
  readings from the probe sensors), together with all the necessary software parameters for the data evaluation
  {probe calibration data, and device frequency and modulation data) in measurement files.

         The formula for each channel can be given as :

                f = carrier frequency [GHz]
                 E; = electric field strength of channel i in V/m



         The RSS value of the field components gives the total field strength (Hermitian magnitude) :

7. RF Emissions Test Procedure
Referenced from ANSI C63.19 -2011 section 5.5.1
a. Confirm the proper operation of the field probe, probe measurement system, and other instrumentation
   and the positioning system.
b. Position the WD in its intended test position.
c. Set the WD to transmit a fixed and repeatable combination of signal power and modulation characteristic
   that is representative of the worst case (highest interference potential) encountered in normal use.
   Transiently occurring start-up, changeover, or termination conditions, or other operations likely to occur
   less than 1% of the time during normal operation, may be excluded from consideration.
d. The center sub-grid shall be centered on the T-Coil mode perpendicular measurement point or the
   acoustic output, as appropriate. Locate the field probe at the initial test position in the 50 mm by 50 mm
   grid, which is contained in the measurement plane, refer to illustrated in Figure 8.2. If the field alignment
   method is used, align the probe for maximum field reception.
e. Record the reading at the output of the measurement system.
f. Scan the entire 50 mm by 50 mm region in equality spaced increments and record the reading at each
   measurement point, The distance between measurement points shall be sufficient to assure the
   identification of the maximum reading.
g. Identify the five contiguous sub-grids around the center sub-grid whose maximum reading is the lowest of
   all available choices. This eliminates the three sub-grids with the maximum readings. Thus, the six areas
   to be used to determine the WD's highest emissions are identified.
h. Identify the maximum reading within the non-excluded sub-grids identified in step g).
i. Indirect measurement method
j. The RF audio interference level in dB (V/m) is obtained by adding the MIF (in dB) to the maximum
   steady-state rms field-strength reading, in dB (V/m)
k. Compare this RF audio interference level with the categories in ANSI C63.19-2011 clause 8 and record
   the resulting WD category rating.
l. For the T-Coil perpendicular measurement location is ≥5.0 mm from the center of the acoustic output,
   then two different 50 mm by 50 mm areas may need to be scanned, the first for the microphone mode
   assessment and the second for the T-Coil assessment.
m. The second for the T-Coil assessment, with the grid shifted so that it is centered on the perpendicular
   measurement point. Record the WD category rating.

9. Measurement System Validation
Each DASY system is equipped with one or more system validation kits. These units, together with the predefined
measurement procedures within the DASY software, enable the user to conduct the system performance check and
system validation. System validation kit includes a dipole, tripod holder to fix it underneath the test Arch and a
corresponding distance holder.
The system performance check verifies that the system operates within its specifications. System and operator
errors can be detected and corrected. It is recommended that the system performance check be performed prior to
any usage of the system in order to guarantee reproducible results. The system performance check uses normal
HAC measurements in a simplified setup with a well characterized source. This setup was selected to give a high
sensitivity to all parameters that might fail or vary over time. The system check does not intend to replace the
calibration of the components, but indicates situations where the system uncertainty is exceeded due to drift or
failure.

<Test Setup>
1.   In the simplified setup for system evaluation, the EUT is replaced by a calibrated dipole and the power source is
     replaced by a continuous wave which comes from a signal generator.
2.   The center point of the probe element(s) is 15mm from the closest surface of the dipole elements.
3.   The calibrated dipole must be placed beneath the arch phantom. The equipment setup is shown below:
4.   The output power on dipole port must be calibrated to 20dBm (100mW) before dipole is connected.

<Validation Results>
Comparing to the original E-field value provided by SPEAG, the verification data should be within its specification of
25 %. Table 6.1 shows the target value and measured value. The table below indicates the system performance
check can meet the variation criterion and the plots can be referred to appendix A of this report.

         HAC RF EMISSIONS TEST REPORT                                                         Report No. : HA913110A
10. Modulation Interference Factor
The HAC Standard ANSI C63.19-2011 defines a new scaling using the Modulation Interference Factor (MIF).
For any specific fixed and repeatable modulated signal, a modulation interference factor (MIF, expressed in dB)
may be developed that relates its interference potential to its steady-state rms signal level or average power level.
This factor is a function only of the audio-frequency amplitude modulation characteristics of the signal and is the
same for field-strength and conducted power measurements. It is important to emphasize that the MIF is valid only
for a specific repeatable audio-frequency amplitude modulation characteristic. Any change in modulation
characteristic requires determination and application of a new MIF
The Modulation Interference factor (MIF, in dB) is added to the measured average E-field (in dBV/m) and converts it
to the RF Audio Interference level (in dBV/m). This level considers the audible amplitude modulation components in
the RF E-field. CW fields without amplitude modulation are assumed to not interfere with the hearing aid electronics.
Modulations without time slots and low fluctuations at low frequencies have low MIF values, TDMA modulations
with narrow transmission and repetition rates of few 100 Hz have high MIF values and give similar classifications as
ANSI C63.19-2011.
ER3D, EF3D and EU2D E-field probes have a bandwidth <10 kHz and can therefore not evaluate the RF envelope
in the full audio band. DASY52 is therefore using the indirect measurement method according to ANSI C63.19-2011
which is the primary method. These near field probes read the averaged E-field measurement. Especially for the
new high peak-to-average (PAR) signal types, the probes shall be linearized by PMR calibration in order to not
overestimate the field reading. Probe Modulation Response (PMR) calibration linearizes the probe response over
its dynamic range for specific modulations which are characterized by their UID and result in an uncertainty
specified in the probe calibration certificate. The MIF is characteristic for a given waveform envelope and can be
used as a constant conversion factor if the probe has been PMR calibrated.
The evaluation method for the MIF is defined in ANSI C63.19-2011 section D.7. An RMS demodulated RF signal is
fed to a spectral filter (similar to an A weighting filter) and forwarded to a temporal filter acting as a quasi-peak
detector. The averaged output of these filtering is scaled to a 1 kHz 80% AM signal as reference. MIF measurement
requires additional instrumentation and is not well suited for evaluation by the end user with reasonable uncertainty.
It may alliteratively be determined through analysis and simulation, because it is constant and characteristic for a
communication signal. DASY52 uses well-defined signals for PMR calibration. The MIF of these signals has been
determined by simulation and it is automatically applied.
The MIF measurement uncertainty is estimated as follows, declared by HAC equipment provider SPEAG, for
modulation frequencies from slotted waveforms with fundamental frequency and at least 2 harmonics within 10 kHz:
1.    0.2 dB for MIF: -7 to +5 dB
2.    0.5 dB for MIF: -13 to +11 dB
3.    1 dB for MIF: > -20 dB
MIF values applied in this test report were provided by the HAC equipment provider of SPEAG, and the worst
values for all air interface are listed below to be determine the Low-power Exemption.

General Note:
1.    EDGE data modes, 16QAM/64QAM are not necessary due the GSM Voice mode, QPSK are the worst case.
2.    According to ANSI C63.19 2011-version, for the air interface technology of a device is exempt from testing
      when its average antenna input power plus its MIF is ≤17 dBm for any of its operating modes.
3.    HAC RF rating is M4 for the air interface which meets the low power exemption.

         HAC RF EMISSIONS TEST REPORT                                                     Report No. : HA913110A



14. Uncertainty Assessment
The component of uncertainly may generally be categorized according to the methods used to evaluate them.
The evaluation of uncertainly by the statistical analysis of a series of observations is termed a Type A
evaluation of uncertainty. The evaluation of uncertainty by means other than the statistical analysis of a series
of observation is termed a Type B evaluation of uncertainty. Each component of uncertainty, however
evaluated, is represented by an estimated standard deviation, termed standard uncertainty, which is
determined by the positive square root of the estimated variance.


The combined standard uncertainty of the measurement result represents the estimated standard deviation of
the result. It is obtained by combining the individual standard uncertainties of both Type A and Type B
evaluation using the usual “root-sum-squares” (RSS) methods of combining standard deviations by taking the
positive square root of the estimated variances. Expanded uncertainty is a measure of uncertainty that
defines an interval about the measurement result within which the measured value is confidently believed to
lie. It is obtained by multiplying the combined standard uncertainty by a coverage factor. For purpose of this
document, a coverage factor two is used, which corresponds to confidence interval of about 95 %. The DASY
uncertainty Budget is showed in Table 12.1.


The judgment of conformity in the report is based on the measurement results excluding the measurement
uncertainty.
