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].
