6. Measurement standards for T-Coil
6.1 Frequency Response
The frequency response of the perpendicular component of the magnetic field, measured in 1/3 octave bands, shall
follow the response curve specified in this sub-clause, over the frequency range 300 Hz to 3000 Hz.
Figure 1.1 and Figure 1.2 provide the boundaries as a function of 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.

     Fig. 1.2 Magnetic field frequency response for WDs with a field that exceeds –15 dB(A/m) at 1 kHz



6.2 T-Coil Signal Quality Categories
This section provides the signal quality requirement for the intended T-Coil signal from a WD. 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. A device is assessed
beginning by determining the category of the RF environment in the area of the T-Coil source.
The RF measurements made for the T-Coil evaluation are used to assign the category T1 through T4. The limitation
is given in Table 1. This establishes the RF environment presented by the WD to a hearing aid.
                                                                   Telephone parameters WD signal quality

7. T-Coil Test Procedure
Referenced to ANSI C63.19-2011, Section 7.4,
This section 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.
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 each measurement position. 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, there might still be RF leakage from the WD, which can interfere
with the desired measurement. Pre-measurement checks should be made to avoid this possibility. All
measurements shall be performed with the WD operating on battery power with an appropriate normal speech
audio signal input level given in ANSI C63.19-2011 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,
Measurement shall be performed at two locations specified in ANSI C63.19-2011 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 the same location as the desired ABM or T-Coil signal (ABM1), and the ratio of desired to 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 following steps summarize the basic test flow for determining ABM1 and ABM2. 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. Confirm that equipment that requires calibration has been calibrated, and that the noise
     level meets the requirements given in ANSI C63.19-2011 clause 7.3.1.
c. The drive level to the WD ise set such that the reference input level specified in ANSI C63.19-2011 Table 7.1 is
     input to the base station simulator (or manufacturer's test mode equivalent) in 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 ANSI C63.19-2011 clause 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. The same drive level shall 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 ANSI C63.19-2011 clause 7.4.4.1.1 and 7.4.4.2.
e. At each measurement location, measure and record the desired T-Coil magnetic signals (ABM1 at fi) as
     described in ANSI C63.19-2011 clause 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.
f. 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 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.)
g. 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 ANSI C63.19-2011 clause 7.3.1.
h. At the measurement location for each orientation, measure and record the undesired broadband audio
     magnetic signal (ABM2) as specified in ANSI C63.19-2011 clause 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).
i. Obtain the data from the postprocessor, SEMCAD, and determine the category that properly classifies the
     signal quality based on ANSI C63.19-2011 Table 8.5.

7.3 Description of EUT Test Position
    Fig.3 illustrate the references and reference plane that shall be used in a typical EUT emissions
    measurement. The principle of this section is applied to EUT with similar geometry. Please refer to
    Appendix C for the setup photographs.

           The area is 5 cm by 5 cm.
           The area is centered on the audio frequency output transducer of the EUT.
           The area is in a reference plane, which is defined as the planar area that contains the highest point
            in the area of the phone that normally rests against the user’s ear. It is parallel to the centerline of
            the receiver area of the phone and is defined by the points of the receiver-end of the EUT handset,
            which, in normal handset use, rest against the ear.
           The measurement plane is parallel to, and 10 mm in front of, the reference plane.

9. T-Coil testing for OTT VoIP Calling
General Notes:
1. The google Duo and SIP calling VoIP application are pre-installed on this device. According to KDB
   285076 D02, all air interfaces via a data connection with VOIP application need to be considered HAC
   testing.
2. The Google Duo only support OPUS audio codec and support 6Kbpa to 75Kbps bitrate.
3. The test setup used for OTT VoIP call is the DUT connect to the CMW500 and via the data application
   unit on CMW500 connection to the Internet, the Auxiliary EUT is connected to the WiFi access point, the
   channel/Modulation/Frequency bands/data rate is configured on the CMW500 for the DUT unit. For the
   Auxiliary VoIP unit which is used to configure the audio codec rate and determine the audio input level of
   -20dBm0 based on the KDB 285076 D02v03 requirement.
4. Codec Investigation: For a voice service/air interface, investigate the variations of codec configurations
   (WB, NB bit rate) and document the parameters (ABM1, ABM2, S+N/N, frequency response) for that
   voice service. It is only necessary to document this for one channel/band.
5. Air Interface Investigation:
   a. Use the worst-case codec test and document a limited set of bands/channel/bandwidths. Observe the
        effect of changing the band and bandwidth to ensure that there are no unexpected variations. Using
        the knowledge of the observed variations, it is necessary to report only a set band/channel/bandwidth
        for each orientation for a voice service/air interface.
   b. According to the ANSI C63.19 2011 section 7.3.2, test middle channel of each frequency band for
        HAC testing for each orientation to determine worst HAC T-Coil rating.

Remark:
Select LTE FDD/LTE TDD one frequency band to do measurement at the worst SNR position was additionally performed
with varying the BWs/Modulations/RB size to verify the variation to find out worst configuration , the observed variation is
very little to be within 1 dB which is much less than the margin from the rating threshold.

Remark:
Select WLAN 2.4GHz and WLAN 5GHz one frequency band to do measurement at the worst SNR position was
additionally performed with varying the BWs/Modulations/data rate to verify the variation to find out worst configuration ,
the observed variation is very little to be within 1 dB which is much less than the margin from the rating threshold.

10. Uncertainty Assessment
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 8.2.
