The study seeks to evaluate the impact of SpeechSensor and StereoZoom 2.0 on speech understanding in noise in dynamic listening conditions in pediatric hearing aid users.
The purpose of this study is to substantiate clinical performance claims regarding the benefit of the SpeechSensor feature on speech recognition in noise for side and rear speech as well as StereoZoom 2.0 benefit data for front speech in noise. In addition, the study will yield myPhonak app usability data and claims regarding children's impressions (confidence, anxiety) when given the opportunity to personalize their beamformer settings in noise during a home trial. Finally, this work will confirm hearing aid intended use for pediatric hearing aid users. Results will inform feature setting, provide critical post-market clinical hearing aid data and support for claims.

Speech intelligibility using AZBio sentences Verbal response accuracy based on percent of words correctly repeated on an open-set sentence recognition in noise task.
Verbal response accuracy based on percent of words correctly repeated on an open-set sentence recognition in noise task. 1. Initial - Personalized Signal-to-Noise-Ratio (SNR) is determined for each participant by finding the point where the participant scores 50% correct individual words within sentences. The personalized SNR is determined from the average of two list for a given condition. (SpeechSensor and SZ2.0 objectives) 2. For comparison conditions - Speech as noise will be presented at the participant's personalized SNR. Speech intelligibility will be determined by accuracy of individual words within sentences. The total words correct is determined for a single list for each condition. (Aided versus unaided, intended use objective).
Time frame: 3 hours
Speech Focus Slider Usability - Performance on a modified PHAST (Practical Hearing Aid Skills Test) tool will be used to document whether participants can successfully modify the Speech Focus slider.
1. Ability to use slider in the app will be determined on the basis of successfully or not successfully completing a single task, "In a situation when you want to use the app, show me what you would do." The child will be reinstructed one time and must successfully perform the desired task to be eligible for the home trial. 2. Ability to successfully use slider in the app will be determined based on successful execution of all of the following tasks correctly): i. Show me what you would do to better hear a person in front; ii. Show me what you would do to hear more of the sounds around you. iii. Demonstrate what you should do when you leave the situation.
Time frame: 3 hours
Preference for having slider
Preference for having the Speech Focus slider accessible via the app will be documented with a Yes/ No question on a subjective questionnaire administered post-home trial.
Time frame: Up to 4 weeks

Confidence and Anxiety
The possible impact of having access to the Speech Focus slider on confidence and anxiety will be measured using subjective ratings on a post-home trial questionnaire (i.e., Likert scale).
Time frame: Up to 4 weeks
