Reducing Listening Effort via primax Hearing Technology

---

1.  According to the article, whats another indicator for the effectiveness of hearing aid fittings beyond improving speech intelligibility that has sometimes been overlooked? improvement in spontaneous acceptance of amplification improvement in physical health improvement in the quality of life reduction in the cognitive demands, or listening effort required for speech understanding to take place.

2.  What is Narrow Directionality? a binaural beamformer that is the first hearing aid technology clinically proven to allow wearers to understand speech better in noisy environments than even those with normal hearing a binaural beamformer which steers directionality towards the back or either side a binaural wind noise reduction algorithm which transfer strategic portions of the audio signal from the side with less wind noise to the other a binaural transient noise reduction algorithm

3.  What are some listening situations which require increased listening effort? situations with excessive background noise listening to a speaker with a pronounced accent listening to very soft speech all of the above

4.  According to the article, why does hearing loss cause increased listening effort? hearing loss has been linked to cognitive disorders such as Alzheimer’s Disease and dementia in difficult listening situations, the hearing-impaired person would constantly be lagging behind in the conversation, missing out on the parts of speech because his brain is already busy processing the previous parts and not able to direct attention to the new input. hearing loss degrades our ability to perceive the speech signal, thereby increasing the demands on cognitive resources involved in selectively attending and interpreting it b & c

5.  Which are the three strategies which SpeechMaster uses to improve the signal? improving the signal based on signal type, direction, and dynamic range improving the signal based on signal frequency, direction, and loudness improving the signal based on signal type, direction, and loudness improving the signal based on signal type, duration, and loudness

6.  According to the article, what is the best way to reduce listening effort? highlighting noise while minimizing target speech minimizing noise while highlighting target speech providing gain for speech frequencies only maximizing noise reduction at all times

7.  Which of the following features is included in the Direction component of SpeechMaster? Narrow Directionality Spatial SpeechFocus EchoShield a & b

8.  How does the intelligent steering of the SpeechMaster preserve spatial cues? In quieter environments where speech is easily understood, TruEar mode ensures that localization cues are preserved. As more noise is introduced and speech intelligibility is increasingly compromised, standard directional microphones can improve SNR for the wearer while still maintaining significant spatial cues. Since signals are processed differently for the left and right hearing aids in the generation of Narrow Directionality, the spatial information of the non-target sound sources is still maintained despite the narrow directional cone All of the above

9.  How does EchoShield reduce reverberation? EchoShield operates on the level difference between the direct sound and the reflected sounds and ensures that the softer reflections are not over-amplified EchoShield increases the gain for the direct sound EchoShield engages aggressive noise reduction EchoShield activates Narrow Directionality to block out reflected sounds

10.  What are the three distinct music programs in HD Music? At Home, At Concert, On Stage Classical, Jazz, Rock & Pop Recorded Music, Live Music, Musician Recorded Music, Live Music, Singer
