** List can be extended to additional pages if needed to list all repairable devices.**

ATTACHMENT E-1: INITIAL PRODUCT EVALUATION

I. Feedback Suppression Test of Gain Stability done with Measurements of Power Concentration Ratio and Blind Listening to Recordings

1. Feedback suppression features will be tested by making measurements of the power concentration ratio (PCR) and by blind listening to recordings to determine whether an aid under test is in an unstable oscillatory state (in feedback). The PCR is the fraction of the total signal power contained in the five frequency bins with the highest power in the output power spectrum of the aid when presented with an input stimulus. When this ratio exceeds 0.5, the aid is in feedback. A recording of the hearing aid output will be made during presentation of the stimulus. Each recording will be reviewed by a pair of listeners that will not know the make/model of the aid used to produce the recording. Each listener will make an independent determination as to whether the aid under test is in feedback. This determination will strictly be a binary one of whether feedback is heard or not. No subjective judgement of sound quality will be made. The gain of the aid under test will also be measured.

2. Recordings, PCR measurements and insertion gain measurements will be made with the aid under test mounted on the right ear of a Knowles Electronics Manikin for Acoustic Research (KEMAR), which meets the requirements of ANSI S3.36-2012, with an ANSI S3.25- 2009 ear simulator in an anechoic chamber. KEMAR will have one neck ring in place, no clothing or wig, and will be configured with the large right ear for behind-the-ear aids (G.R.A.S.

Part # KB 0065, previously Knowles Part # DB 065), and the straight ear canal extension that has a constant (non-tapered) canal diameter of 7.5 mm (G.R.A.S. Part # RA0237).

3. The reference point of the manikin, which is at the midpoint of the ear canal axis, will be located at the test point, which is 1.00 m ± 0.05 m from the front surface of the loudspeaker enclosure on the test axis. This axis is normal to the front surface of the loudspeaker and passes through the center of its cone. The manikin will be oriented facing the loudspeaker so that the ear canal axis is normal to the test axis.

4. Recordings/Data will be acquired using a white noise input stimulus with a long-term average free-field sound pressure level (SPL) of 50 dB at the test point (i.e., broadband SPL measured with the manikin absent). The white noise is Gaussian, has a crest factor of 14 dB, and covers the frequency range from 200 Hz to 10,000 Hz.

5. The offeror shall provide a receiver-in-the-canal (RIC) hearing aid with non-rechargeable power (Group 3 - Category 1), an attached 50-dB receiver and an open dome. The RIC tubing attached shall have been selected by the offeror to have the appropriate insertion depth (into the simulated ear canal of KEMAR) as determined by the offeror’s measurement tool designed for this purpose. The open dome attached shall have the diameter closest to 7.0 mm of those available from the offeror, but it shall not exceed 7.0 mm.

6. The sample shall be set to operate in omnidirectional mode. The feedback suppression feature shall be active. All noise reduction/suppression features shall be deactivated to prevent attenuation of the output/gain due to the nature of the input stimulus. All frequency altering features (e.g. frequency transposition, frequency compression, etc.) except for any that are inherent to the feedback suppression feature shall also be deactivated. The offeror shall program the sample so that the applicable settings are activated when power is applied to the aid.

7. The sample shall be programmed so that the frequency-dependent insertion gain of the aid meets or exceeds the values shown in Table 1 when the specified white noise stimulus is applied. Note that the values listed in the table are not targets, but rather minimum requirements to be met or exceeded without feedback. To help ensure that the aid is submitted set to adequate gain, also submit measured insertion gain data acquired with the specified white noise and the sample set as it will be when submitted. For this purpose, use of a white noise input stimulus with the same specifications is preferred but not required.

TABLE 1. Minimum required values of stable insertion gain One-Third Octave Frequency Band (Hz) Minimum insertion gain (dB) 1600 17 2000 20 2500 22 3150 24 4000 28 5000 28

8. Requirements for Results of Feedback Suppression Tests

(a) The hearing aid gain settings shall provide stable gain that meets or exceeds the minimum gain requirements listed in Table 1. The values listed in the table are not targets, but rather minimum requirements to be met or exceeded without feedback. (b) Either both listeners, or at least one listener and the PCR measurement, must determine that the aid was stable when its output was recorded/measured. For the PCR measurement determination, the aid is stable if the PCR is no greater than 0.5.

II. ANSI/ASA S3.22-2014 Total Harmonic Distortion and Equivalent Input Noise Level Tests

1. Total harmonic distortion (THD) and equivalent input noise level (EIN) measurements will be completed according to the procedures specified in ANSI/ASA S3.22-2014. Samples shall be programmed by the offeror to the reference test setting as specified in ANSI/ASA S3.22- 2014 in the same manner as they are typically programmed by the offeror for these tests at its measurement facilities. A “test mode” setting may be programmed if necessary. The output of the hearing aids will be measured in a 2cc coupler that meets the requirements of ANSI/ASA S3.55 Part 5-2014. A closed coupler configuration as described in ANSI/ASA S3.22-2014 that is suitable for the type of hearing aid under test will be utilized. For custom ITE and RIC devices, the HA-1 configuration will be used with putty to seal around the device tip amplified sound opening at the coupler opening. For BTE devices, the HA-2 configuration will be used.

2. In addition to the THD and EIN measurements, the reference test gain (RTG) will be measured as a means of confirming the reference test setting. The RTG measurement will be done as specified in ANSI/ASA S3.22-2014, using a sinusoidal test signal at an input SPL of 60 dB, and calculated as the average of gains in decibels at 1000 Hz, 1600 Hz and 2500 Hz.

3. For Group 1, Group 2, or Group 3, a device shall be submitted by the offeror for testing for each category offered. Additionally, a power and super-power BTE hearing aid (Group 2 – Category 1) shall be submitted.

(a) BTE hearing aids shall be configured with an ear hook attached

(b) RIC hearing aids shall be configured with a receiver and an open or closed dome attached

(c) Advanced receivers shall be configured with a compatible group 3 RIC hearing aid and an open or closed dome attached

4. Requirements for Results of THD and EIN Tests For each sample, the average of the THD values measured at 500 Hz, 800 Hz, and 1600

Hz shall be less than 5%, and the measured EIN shall not exceed 29 dB. For power instruments, the EIN measured according to these procedures shall not exceed 32 dB.

5. Requirements for the Measured RTG For each sample, the specification sheet for the hearing aid model shall be submitted by the offeror. The measured RTG for a given sample shall match (within ± 6 dB) the value reported on the specification sheet for the model of the sample.
