Physiological, Behavioural and Subjective Measures of Listening Effort

Each participant will be fitted with noise reduction disabled. Disabled means that no sound processing algorithm that removes noise from the speech signal is active.

Each participant will be fitted with the noise reduction program on the same hearing aid. The principle of the noise reduction algorithm is to remove noise from a speech signal with the aim of improving the speech intelligibility and comfort.

Each participant will be fitted with a second noise reduction program on the same hearing aid. The parameterization of this NR algorithm differs from that in NR(1).
