Q

patient response format: Closed Sets

A

provide limited set of response choices; easier than open sets. used for testing cochlear implants.

A

Modify emotions; Focus on feelings and fostering emotional adjustment. Find congruence with self. Use unconditional; positive regard. Employ empathetic understanding

35
Q

Time Course of HL

A

how does the loss change over time?

-stable, sudden, progressive or rapidly progressive

36
Q

If ACT is within normal limits and BCT for that same frequency are within normal limits and don’t differ from one another by 10+ dB, then this individual has…

A

normal hearing

37
Q

If ACT is in normal range and BCT is in normal range, but the BCT is better than ACT by 10+dB, then there is …

A

Conductive Dysfunction and referral is required

38
Q

If ACT is outside normal limits and BCT is within normal limits, and BCT is 10+dB better than the ACT, then the loss is…

A

Conductive

39
Q

Amplifier

A

Increases sound intensity. almost all are digital and replaced analog versions. 3 stages to amplification process: preamplifier, signal-processing and output stage

40
Q

If the ACT is outside normal limits and the BCT is outside normal limits but the BCT is better than the ACT by 10+dB, then the loss is…

A

Mixed

41
Q

Receiver

A

Is an output transducer that changes electrical voltage back into sound pressure. sounds are converted back into acoustic energy; can be described as a mini loudspeaker or a microphone in reverse

42
Q

Spondee

A

2 syllable words with equal stress on each syllable

43
Q

46
Q

UCL

A

47
Q

patient response format: Open Sets

A

no response choices and no contextual cues are provided to patients

48
Q

patient response format: Closed Sets

A

provide limited set of response choices; easier than open sets. used for testing cochlear implants.

49
Q

Signal/Speech to noise ratio

A

the level of signal you want to listen to v. everything else that is just noise

  • speech stimuli: 10 dB louder than noise = +10 SNR
  • speech stimuli: 10 dB softer than noise = -10 SNR
50
Q

Dynamic Range

A

the difference between threshold of discomfort and threshold of audibility

51
Q

3 aspects of understanding

A

1) the loudness of things
2) tuning of things
3) processing of things

52
Q

CROS

A

Contralateral Routing of Signal (AC or BC)

  • used with unilateral and single sided deafness
  • no useable hearing in bad ear
  • normal or near normal hearing in good ear
53
Q

BICROS

A

Bilateral Contralateral Routing of Signal

- No useable hearing in bad ear, but there is hearing in the better ear as well

54
Q

BAHS

A

Bone Anchored Hearing System

- 2 uses: conductive/mixed HL when Air conduction hearing aid is contraindicated; and SSD

55
Q

BAHS involves…

A

inserting a titanium screw into the mastoid area behind the ear

provides hearing by bone conduction

56
Q

Psychosocial Support

A

Helps patient manage psychological and social difficulties associated with their hearing loss. Aimed to increase self-acceptance; self- confidence. Helps understand how hearing loss impacts life

57
Q

Microphone

A

May be directional or omnidirectional. Can be switched between (some automatically according to environment)

58
Q

Directional

A

more sensitive to sound originating front of the user rather than the back. These enhance the signal-to-noise ratio and are better in noisy environments

59
Q

Omnidirectional

A

sensitive to sound from all directions

60
Q

Amplifier

A

almost all are digital and replaced analog versions. 3 stages to amplification process: preamplifier, signal-processing and output stage

61
Q

Peak- clipping

A

limits loud noises from passing through but may introduce distortion

62
Q

Receiver

A

sounds are converted back into acoustic energy; can be described as a mini loudspeaker or a microphone in reverse

63
Q

BTE

A

Behind the ear. Mild to profound. Flexible/ customizable. Fewer feedback problems, easy maintenance

64
Q

RITE

A

Receiver in the ear. Mild to severe. Small casing behind the ear, short receiver sits in ear. Custom fit, cosmetic appeal and may distort sound of user’s voice

65
Q

ITE

A

In the ear. Mild to Severe. fit in external ear

66
Q

ITC

A

In the canla. Mild to moderately-severe. Fits in external ear. fill less of cochlea that ITE. Custom fit, cosmetic appeal and may distort sound of user’s voice

67
Q

Completely in the canal. Inside ear canal, remote control for adjustment, reduces feedback and improves localization, virtually invisible, distort sound of user’s voice and high maintenance.

68
Q

How to fit hearing aid GOAL

A

make soft sound audible, moderate sound clear and comfortable, and loud sound should be loud but not uncomfortable.

69

One hearing aid

70
Q

2 hearing aids. eliminates head shadow, loudness summation

71
Q

A

what comes out of the receiver- linear processing happens in between

73
Q

Processing Gain

A

consistent across intensities, up until saturation point

74
Q

Peak clipping

A

clipping of peaks of signal that reaches saturation level (point where an amplifier no longer provides an increase in output compared to input)

75
Q

Compression processing

A

varying output as a function of input. Louder inputs not given the same gain as softer inputs. Goal= decrease dynamic range of sound environment so that all sound can be placed in the REDUCED dynamic range

76
