4. HAC RF Emission
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 C63.19 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.

  Probe Tip Description:

        HAC field measurements take place in the close near field with high gradients. Increasing the
        measuring distance from the source will generally decrease the measured field values (in case of the
        validation dipole approx. 10%&per mm).




  5.3 System Hardware



   The data acquisition electronics (DAE) consists of a highly sensitive electrometer—grade preamplifier with
  auto—zeroing, a channel and gain—switching multiplexer, a fast 16 bit AD—converter and a command decoder|
  and control logic unit.




   The SPEAG DASY system uses the high precision robots (DASY5: TX90XL) type from St&ubli SA (France).
  For the 6—axis controller system, the robot controller version (DASY5: CS8c) from Staubli is used.

  5.4 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 :
                                                                     ,       _of

                                                                                   i

                cf = crest factor of exciting field (DASY parameter)
                dep; = diode compression point (DASY parameter)



        From the compensated input signals, the primary field data for each channel can be evaluated :


                                              E—field Probes : E; =      /m
                                                                                       1


       with     V; = compensated signal of channel i, (i= x, y, z)
                Norm; = sensor sensitivity of channel i, (i=x, y, z), pV/(V/m)2 for E—field Probes
                ConvF = sensitivity enhancement in solution
                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) :


                                                     Erot =   _[E2 + E$ + E2

       The primary field data are used to calculate the derived field units.

6. 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.



6.1 Purpose of System Performance Check
    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.

    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:

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
           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)
     j)    Compare this RF audio interference level with the categories in ANSI C63.19-2011 clause 8 and
           record the resulting WD category rating.
     k)    For the T-Coil mode M-rating assessment, determine whether the chosen perpendicular
           measurement point is contained in an included sub-grid of the first scan. If so, then a second scan
           is not necessary. The first scan and resultant category rating may be used for the T-Coil mode M
           rating.
           Otherwise, repeat step a) through step i), with the grid shifted so that it is centered on the
           perpendicular measurement point. Record the WD category rating.

8. 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.

  Remark:
  1.   The HAC measurement system applies MIF value onto the measured RMS E—field, which is indirect method in ANSI
       C63.19 2011 version, and reports the RF audio interference level.
  2.   The uncertainty is 0.20B of MIF ranges from —7dB to +5dB.GSM850 band with rating M4 for LAT Antenna ,M4/M3 for
       UAT Antenna, GSM1900 band with rating M4 for LAT Antenna, M3 for UAT Antenna would not be affected
       considering the MIF uncertainty.
  3.   There is no special HAC mode software on this EUT.
  4.   Detail Antenna Location information please refer to Appendix D.

12. 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.
