- Sonova AG
- Brief Summary
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.
- Detailed 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.

- Primary Outcome Measures
Name Time Method Speech Intelligibility score using the AZ Bio Sentence Test-teacher condition One day (Visit 1) Sentences are presented from a front speaker located 8.5 feet away from participant. Diffuse background noise is presented from four corner speakers. Various Signal to Noise Ratios (SNR) will be tested: +4 dB, +2 dB, and -2 dB. The number of words correctly repeated will be calculated and expressed as a percentage for each SNR level. A higher score is better.
Speech Intelligibility score using the AZ Bio Sentence Test- small group condition One day (Visit 1) Sentences are presented randomly from three different speakers, located around a small table with the participant, simulating a small group at a table. Diffuse background noise is presented from four corner speakers. Various Signal to Noise Ratios (SNR) will be tested: +4 dB, +2 dB, and -2 dB. The number of words correctly repeated will be calculated and expressed as a percentage for each SNR level. A higher score is better.
- Secondary Outcome Measures
Name Time Method Listening Fatigue using the Vanderbilt Fatigue Scale for Children Two days (Visit 2 and Visit 3) Ten questions related to fatigue, answers rank from 1 (never) to 5 (almost always). Total scores can range from 10 to 50, with higher scores indicating more self-perceived fatigue.
Subjective Preferences of participants Two days (Visit 1 following the lab testing, and Visit 3, following the field trial) Participants will be asked to rank their preference for the microphone systems using a Likert type of rating scale (1-5), where a lower score (\<3) would indicate preference for the partner mic and a higher score (\>3) will indicate preference for the Roger Touchscreen.
