Exam Preview for 37723: Study Reveals Signia Split Processing Signi

Study Reveals Signia Split Processing Significantly Improves the Signal-to-Noise Ratio

Please note: exam questions are subject to change.

1. What is the basic principle behind split processing? It processes sounds arriving from different directions separately. It always uses two different gains at the two ears. It uses half of the features to achieve longer battery life. It splits the processing between the hearing aid and the wearer’s smart phone.
2. How many processing channels are used in the Augmented Focus? 2 12 24 48
3. What effect does the split processing have on speech? Speech becomes highly compressed. Speech may be provided less gain reduction than noise. Speech and noise become equally loud. Speech is always maintained at a loud level.
4. In the study, which processing condition resulted in the highest output SNR? unaided omnidirectional ADIR+DIR split processing
5. On average, how much did split processing improve the SNR compared to single stream processing? 4.2 dB 2 dB 1 dB 0 dB
