Full description

Speech intelligibility will be evaluated for school age children with hearing loss in a simulated classroom environment, using Phonak hearing aids and receivers and two different microphone transmitters: a Roger Touchscreen mic and a fixed directional microphone. The simulated classroom environment will include a teacher condition, in which speech is presented from a distance in front of the participant, and a small-group condition, in which speech is presented randomly from three different speakers around the participant. Both conditions will have diffuse background noise, and the various SNR (Signal to Noise Ratio) levels will be tested.

Subjective preference and fatigue questionnaires will also be collected from the participants after the use of each transmitter.
