Accordingly, there is growing need for an applicable objective test that represents aided thresholds and cortical processing of amplified sounds.
For all aided conditions and at all frequencies, the aided thresholds are significantly better than the unaided thresholds.
It is not possible to perform real ear measurements; soundfield aided thresholds, sentence reception thresholds (SRTs), and self-reports were obtained to evaluate the outcomes.
In implanted patients, aided thresholds were measured (Interacoustic AC30 Audiometer connected to a Pioneer A 103 amplifier, JBL TLX130 loudspeakers) with subjects wearing their sound processor on user settings.
After an acclimatization period of 30 minutes, the following three measurements were performed in the sound field: (1) aided thresholds using narrow band noise, (2) aided speech understanding in quiet using German monosyllabic words (Freiburger word test) at a presentation level of 65 dB SPL, and (3) aided speech understanding in noise using the German Oldenburger sentence test (OLSA) [ 19].
The aim of the study was to observe and report the long-term audiological progress and speech development of children with CC deformity after CI by means of CAP, SIR, MAIS, MUSS scores and CI aided threshold.
Although the participants felt that their hearing aids were fitted appropriately, aided hearing thresholds obtained in the soundfield were improved to 42 dB HL, which meant that some of the weaker signals were not audible.
In order to assess the aided benefits with the implant, aided soundfield thresholds were measured with warble tone signals presented at 90 degree azimuths, with the left ear both plugged and muffed.
Additionally, VOI were defined on the averaged PET image acquired over time interval 4 4.5 h p.i.; to investigate possible differences in kinetics within tumor tissue, up to three VOI were defined in areas showing relatively high (VOIHigh), average (VOIAvg), and low (VOILow) PET signal, as determined visually with the aid of thresholding.
These results are consistent with findings in aided soundfield thresholds.
Audiologically, all five patients demonstrated an average improvement of aided soundfield thresholds of approximately 35 dBHL with the Carina device.
