Occurrence of Device Related Adverse Events |
The number of Device Related Adverse Events will be monitored and totaled. Each Adverse Event is measured using a severity scale of: mild, moderate, or severe. The causality is measured with a scale of: Not related, unlikely, possible, probable, and causal relationship. |

Preference Rating |
Subjects will answer a questionnaire that asks them to choose which program that they preferred. The questionnaire gives Program 1 or Program 2 as the choices as well as a no Preference option for those that did not notice a difference between the two. The percentage of subjects that chose each Program will be calculated to determine if more preferred the optimized music program. |

Sound Perception Test - Pitch |
The sound perception test is called the Adaptive Music Perception test. It is tested in the lab with digitally synthesized recordings of components of tones. It tests the overall perception of Meter with pitch (in Hz). A lower score is better. A higher score means that it took higher Levels of Hz to perceive a difference between musical notes.The subjects are tested in the unaided, aided with the standard program, and aided with the test (optimized) program. The scores will be averaged and analyzed to determine if one program results in better (lower) test scores. |

Music Sound Quality Rating |
The sound quality of the devices when listening/playing music will be rated using a questionnaire. The questionnaire asks subjects to rate various aspects of the sound using a 5-point scale with 1 being the worst answer and 5 being the best. The questionnaire will be answered for Program 1 and Program 2. The scores for each question will be averaged across subjects and the difference between the two programs calculated to determine if one music program results in better sound quality scores. A positive score is in favor of the fine-tuned program and a negative score would be in favor of the standard program. They will test Program 1 and Program 2 during the same period as they have the ability to use a button on the Hearing aid to switch between programs. |

Sound Perception Test - Duration |
The sound perception test is called the Adaptive Music Perception test. It is tested in the lab with digitally synthesized recordings of components of tones. It tests the overall perception of duration (in milliseconds). A lower score is better. A higher score means that it took longer in milliseconds to perceive a difference between musical notes.The subjects are tested in the unaided, aided with the standard program, and aided with the test (optimized) program. The scores will be averaged and analyzed to determine if one program results in better (lower) test scores. |

Sound Perception Test - Level |
The sound perception test is called the Adaptive Music Perception test. It is tested in the lab with digitally synthesized recordings of components of tones. It tests the overall perception of Meter with Level (in decibels). A lower score is better. A higher score means that it took higher levels in dB to perceive a difference between musical notes.The subjects are tested in the unaided, aided with the standard program, and aided with the test (optimized) program. The scores will be averaged and analyzed to determine if one program results in better (lower) test scores. |

Sound Perception Test - Brightness |
The sound perception test is called the Adaptive Music Perception test. It is tested in the lab with digitally synthesized recordings of components of tones. The perception of the Timber of music is tested by the brightness (measured in dB). Lower scores are better. A higher score means that it took higher levels in dB to perceive a difference between musical notes.The subjects are tested in the unaided, aided with the standard program, and aided with the test (optimized) program. The scores will be averaged and analyzed to determine if one program results in better (lower) test scores. |

Sound Perception Test - Attack |
The sound perception test is called the Adaptive Music Perception test. It is tested in the lab with digitally synthesized recordings of components of tones. The perception of the Timber of music is tested by the attack (measured in Hz). Lower scores are better. A higher score means that it took higher levels in Hz to perceive a difference between musical notes.The subjects are tested in the unaided, aided with the standard program, and aided with the test (optimized) program. The scores will be averaged and analyzed to determine if one program results in better (lower) test scores. |

Sound Perception Test - Spectral Irregularities |
The sound perception test is called the Adaptive Music Perception test. It is tested in the lab with digitally synthesized recordings of components of tones. The perception of the Timber of music is tested by the spectral irregularities (measured in dB). Lower scores are better. A higher score means that it took higher levels in dB to perceive a difference between musical notes.The subjects are tested in the unaided, aided with the standard program, and aided with the test (optimized) program. The scores will be averaged and analyzed to determine if one program results in better (lower) test scores. |
