ReSound Government Services: Features and Benefits of ReSound LiNX Quattro

---

1.  What is input dynamic range? The range between the softest and loudest speech sounds known The dynamic range of the patient's hearing between threshold and uncomfortable listening level The intensity range between the softest and loudest sounds that are converted from the acoustic environment and delivered to the hearing aid processor The range between inaudible sound and hearing aid saturation level

2.  Which is NOT true of input dynamic range? Increasing it has a great effect on sound quality of music because music has greater peaks in level and is often enjoyed at higher levels It reduces loud transient signals to increase comfort for the listener Increasing it is making use of the full capabilities of the MEMS microphones Increasing it provides quality without distortion for loud sounds and clarity without added circuit noise for soft sounds

3.  Which is NOT a limiting factor of input dynamic range? Classifier Hearing aid microphone Processing chip Analog-to-digital convertor

4.  What is NOT improved by extended bandwidth up to 9.5 kHz? Sound Shaper Spatial Sense Streaming quality Expansion

5.  What is the purpose of impulse noise reduction? To make a patient less impulsive To make loud, sudden, short duration sounds less annoying for the listener To reduce annoyance from soft, long duration noises like ventilation fans To increase the gain for loud, sudden, short duration sounds

6.  Annoyance from the sound of plates being stacked should be lessened by which feature? Impulse noise reduction Increased input dynamic range Extended bandwidth Spatial Sense

7.  Which of the following statements is true regarding extended bandwidth? The All-Around program was preferred for listening to music over streaming from an iPhone The TV streamer was preferred for listening to music over streaming from an iPhone There was no difference in preference ratings for music listening between streaming from and iPhone, the TV streamer and the Music program The All-Around program was preferred for listening to music over streaming from the TV streamer

8.  Which of the following is an improvement found in ReSound LiNX Quattro from the new chipset? Extended bandwidth Increased input dynamic range New wireless radio All of the above

9.  The new chipset reduces power consumption by how much? 40% 20% 15% 10%

10.  How has ear-to-ear performance been improved from the new chipset? 2.4 GHz data transfer is more efficient The radio chip gives up to 5dB better sensitivity The radio chip gives up to 10dB better sensitivity Both A&B
