Psychoacoustic models for speech intelligibility and loudness can be used successfully for deriving a prescriptive fitting rule specifically to high frequency hearing losses. This article describes the development of a new prescriptive fitting algorithm for high frequency hearing losses, OPEN, including a detailed rationale and supporting clinical studies.
Learning Outcomes
- As a result of this Continuing Education Activity, readers will be able to define Open Loop Gain (OLG) measurement and explain the purpose and relevance in regard to fitting open canal hearing instruments
- As a result of this Continuing Education Activity, readers will be able to describe the rationale for the development of the OPEN algorithm
- As a result of this Continuing Education Activity, readers will be able to explain the outcomes of studies of the OPEN algorithm with regard to ratings of sound quality, feedback, speech intelligibility
