Objective:
To evaluate the validity, clinical utility, barriers and facilitators of the manikin-based audiometric simulator, Clinical Assistant for Research and Learning.
Design:
The validity, clinical utility, barriers, facilitators and simulation accuracy were evaluated via an online questionnaire and in-person pure-tone audiometric assessments.
Study Sample:
A total of 38 participants (age range 21-63) completed the study. All participants had formal training in pure-tone audiometric assessments. Participants were audiology students, registered practicing audiologists, hearing instrument dispensers, and undergraduate students.
Results:
The programmed and measured audiograms had an absolute agreement within 5 decibel hearing level. Ease of use, clarity of workflow, realism, and feasibility in clinical practice were the reported facilitators, whereas cost and availability of technical support were the identified barriers to implementation.
Conclusions:
The manikin-based simulator was shown to be an accurate and valid tool in practicing pure-tone audiometric procedures. Clinical applications and future directions were also discussed.
