Sound Quality as the Key to User Acceptance

---

1.  Why is it important for hearing aid processed signals to sound natural to the user? Hearing aid use may be reduced or hearing aids may be rejected due to poor sound quality It is not important; sound quality does not matter to hearing aid wearers Because most users report that sound quality is more important than audibility Because a natural sound quality is required for hearing aids to meet ANSI standards.

2.  People with a greater degree of hearing loss tend to have: a larger range of emotional responses compared to age matched normal hearing subjects the same range of emotional responses as age matched normal hearing subjects a reduced range of emotional responses compared to age matched normal hearing subjects the range of emotional responses is not related to hearing loss

3.  Hearing aid processing can: achieve better hearing than normal in certain difficult listening conditions improve speech recognition by more than 50% due to beamforming technology significantly and measurably reduce listening effort all of the above

4.  When the binaural beamforming feature was compared between Signia primax and Signia Nx, the following was found: the two were equal in SNR improvement the Nx was about .5 dB better than primax for open and vented fittings for open fittings, the improvement with the Nx was about 1 dB, and with a vented fitting, the improvement was over 2 dB over primax the primax was about 1-2 dB better than the Nx for both open and vented fittings

5.  A test of localization with Signia Nx found: poorer performance than Signia primax better performance than omnidirectional only slightly poorer performance than TruEar processing, and an improvement over Signia primax identical results as with Signia primax

6.  Addressing sound quality problems with respect to own voice is important because: it will help with audibility of environmental sounds user's acceptance of his or her own voice can impact first fit acceptance of hearing aids it will help with understanding speech in noise it will provide a better match to target for soft sounds in the real ear verification

7.  How does Nx Own Voice Processing (OVP) work? Using OVP, the hearing aid can detect the user's voice, and then instantaneously alter the gain and output to individualized programmed values. OVP is a special directional microphone pattern deployed to pick up the significant other's voice. OVP processes human voices independently from all other sounds. OVP applies unique processing to the target speaker's voice for improved speech understanding

8.  According to the article, general perception of sound quality is influenced by: localization perception of own voice sound quality of high inputs all of the above

9.  What is the input limiter for Signia Nx? 90 dB SPL 100 dB SPL 113 dB SPL 125 dB SPL

10.  Sound quality for streamed music signals: is the same between manufacturers, as long as they use the same Bluetooth standard is the same as for signals received via the hearing aid microphones is not important for hearing aid wearers depends on the music genre
