4.2 Speech Reception Threshold in Noise
Compared
with the age-related control group, the children with SSD in our study
showed significantly higher (worse) SRTs in all testing conditions. When
tested with BCDs, SRTs became better in all three test conditions (all
p<0.05). This aided benefit is in line with the results
presented in a study by Li-Mei [12], in which the speech tests in
competing speech in separated configurations were performed on SSD
subjects fitted with a semi-implantable bone conductor and CROS.
However, in another study regarding the SRT of ADHEAR using adhesive
adapters in patients with SSD, no statistical difference was found
between the unaided and aided conditions [7]. This unsatisfactory
outcome may be due to the lower pressure provided by the adhesive
adapter compared to the headband used in our study [10].
