Questions 1-9 refer to the following Case 1: This patient is an 82-year-old gentleman with a history of a gradually progressive hearing loss in both ears, over the last 15 years.  He states that he has difficulty hearing, especially in groups and that he understands better when people speak more slowly.  This is the first complete hearing evaluation he has ever received.  Consider his history and the audiometric data below, and then answer the following questions about this case:     250 Hz   500 Hz   1000 Hz   2000 Hz   3000 Hz   4000 Hz   8000 Hz   Right Ear   Air Conduction   30 dB HL   35dB HL   40dB HL   55 dB HL   70 dB HL   70 dB HL   70 dB HL   Left Ear   Air Conduction    30 dB HL   30 dB HL   40 dB HL   55 dB HL   65 dB HL   70 dB HL   70 dB HL   Unmasked   Bone Conduction   25 dB HL   35 dB HL   35 dB HL   55 dB HL   65 dB HL   70 dB HL   ———-       Otoscopy   Tympanograms   SRT   WRS   Right Ear   Non- impacted cerumen both ears   Type A both ears   45   76%   Left Ear   45   72%     Question 6: Regarding audiological intervention for this gentleman’s hearing loss:

The principle of operation of an FM listening system is:

Word Recognition Scores are obtained using:

The patient whose audiogram is shown here is age seven years. The degree of hearing loss is:

An otoacoustic emissions test measures: 

Audiograms contain the results of an audiological evaluation.  On the graph, the horizontal axis represents:

Auditory information from each ear is represented in both cerebral hemispheres.

Based on what you know about dynamic range, compared to a person who has normal hearing, if a person’s hearing thresholds are all at 40 dB HL, this person’s dynamic range would be:

A bone-conduction vibrator applied to the the skull could result in the tone being heard in:
