Clinical Fittings
A way to demonstrate that a patient's goals have been met
What is Validation?
Analyzes perceived effect of hearing loss on emotional and social adjustment in the elderly
What is the HHIE?
Written plan with explicit instruction on hearing aid use over a period of time
What is a graduated wearing schedule?
Result of poor ear mold fit or excessive gain
What is feedback?
Representation of HA output in response to the spatial origin of the signal
What are Polar Plots?
A way to ensure the hearing aids meet established standards
What is Verification?
Evaluates success of fitting, with one question covering each of the 7 outcome domains
What is the IOI-HA?
Two groups of activities provided to patients after their initial fitting
What are structured and unstructured activities?
To remove this, use a pencil eraser or swab with cleaner
What is contact corrosion?
Describes a patient's hearing health journey in distinct stages

What is SNR Loss?
Used to determine if normal loudness perception has been accomplished
What is the PAL?
Opportunity to share experiences, learn communication strategies, and reduce stigma with other hearing aid users
What is Group Audiologic Rehab?
Can lead to intermittency, reduced output, and battery corrosion problems
What are moisture problems?
Assesses each channel for noise through modulation detection
What is Gain-Reduction DNR?
Used to determine whether or not a patient's scores are the same or different
What is the Critical Difference?
Used to evaluate success of fitting and patient experience
What is the SADL?
Required by the FDA to review with the patient at initial fitting appointment
What is the user instructional brochure?
Results in squealing when earhook has been removed
What is internal feedback?
Feature allowing for channel specific directionality
