1.          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. 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
    RF Magnetic-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.

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.

IV.           Test Procedure

       1. Ambient Noise Check per C63.19 §6.2.1
             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 less 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 5-1)
             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.9.1):
                                                                                         V
                                                                                       N( )
                                                                             NI           R
                                                                      Hc           
                                                                                  3
                                                                           r 1.25     r 1.25 3
                                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=10.193Ω and using V=57mV:

                                                                             0.057
                                                                           20  (  )
                                                                  Hc       10.193  1.0003 A / m
                                                                       0.08  1.25 3
                        Therefore a pure tone of 1kHz was applied into the coils such that 57 mV was observed
                        across the 10 Ω resistor. The voltmeter used for measurement was verified to be capable

                c.   Frequency Response Validation

                     The frequency response through the Helmholtz Coil was verified to be within 0.5 dB
                     relative to 1 kHz, between 300 – 3000 Hz using the ITU-P.50 artificial speech signal as
                     shown below:

                     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

                     The ABM2 result is a power sum from 100 Hz to 10 kHz with half-band integration and A-
                     weighting. 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 5-9). Therefore the
                     setup in this step was used to verify the power sum post-processing for ABM2
                     measurements. See below block diagram:

                     The power summed output results for a known input were compared to the multi-meter
                     results to verify any deviation in the post-processing implemented with the power-sum.

                          A multitone signal was applied to the handset such that the phone acoustic
                          output was stable within 1dB over the probe settling time and with the acoustic
                          output level at the C63.19 specified levels (below). The measurement step size
                          was in 2 mm increments at a distance of 10 mm between the surface of the

                                  After scanning, the planar field maximum point was determined. The position of
                                  the probe was moved to this location to setup the test using the sound check
                                  system.
                                  These steps were repeated for the other T—coil orientations (of axial, radial
                                  transverse, or radial longitudinal) per Figure 5—16 after a T—colil orientation was
                                  fully measured with the sound check system.

VII. Wireless Device Channels and Frequencies

The frequencies listed in the table below are those that lie in the center of the bands used for cellular
telephony. Low, middle and high channels were tested in each band for FCC compliance evaluation to
ensure the maximum emission is captured across the entire band.

To facilitate setting of a base station simulator for ABM measurements, specific band plan channel
numbers are listed that may be used in lieu of the band center frequencies.

             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.

11.         CONCLUSION

The measurements indicate that the wireless communications device complies with the HAC limits
specified in accordance with 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.
