Puretone audiogram showed moderate to severe sensorineural hearing loss from 250 to 2000 Hz bilaterally. No responses recorded at higher frequencies at the audiometric limit.
Speech audiometry showed reduced speech discrimination abilities at high intensities. However, this is consistent with her puretone audiometric results.
Tympanometry showed normal tympanometric peak and pressure bilaterally. Absent acoustic reflexes were noted at all test frequencies for both ears.
B. Characteristics and limitations of Sue’s current hearing aids.
One of the first things, perhaps the most important during hearing aids fitting, is to provide appropriate gain for the patient after a thorough hearing assessment. Oticon Intiga RITE (receiver in the ear) is aimed at an immediately comfortable fit and minimal occlusion to thus minimize unnatural sensations. To use an RITE with open fit domes, Sue needs to have good low frequency hearing. Apparently, it cannot provide enough gain Sue needed in the fitting software. It uses smaller (size 10) batteries compared to batteries used by many other miniature hearing aids (size 312 or 13), which could also pose management issues.
Intiga 6‘s modulation based noise management does not allow channel-specific noise reduction, compared to TriState Noise Management. Modulation based noise management assesses the likelihood of rather constant noise in specific frequency regions and tends to be sensitive to the presence of any noise, whether speech is also
