Primary | The signal-to-noise ratio (SNR) benefit for speech in noise (reported in decibel, dB) | Patients are tested in a sound attenuated booth (the crescent of sound) with nine audio stands, an equipment cabinet, and a testing station for the assessment of spatial-listening skills. A 'Speech in noise' test was used. In this test, recorded spoken sentences are presented from straight ahead (0°) while noise is also coming from 90° to the left or right from the participant, who is asked to repeat the sentence. The number of keywords successfully repeated is recorded and repetition of at least three keywords per sentence is required to judge correct performance. The level of the sentences and the background noise are adaptively varied to estimate the signal-to-noise ratio (SNR) for 50% correct performance. The test was conducted with the participant using the frequency modulated systems (aided condition) or not using the frequency modulated systems (unaided condition). The level of SNR is reported in dB. | week 1 | No |
