EVIDENCE BASED PRACTICE
knowing why you make your choice
![Page 10: Widex Ireland ISHAA presentation](https://reader036.vdocuments.mx/reader036/viewer/2022070313/554bf376b4c9056b348b55e0/html5/thumbnails/10.jpg)
EVIDENCE BASED PRACTICE
EVIDENCE-BASED PRACTICE COMBINES THE BEST AVAILABLE EVIDENCE FROM RESEARCH WITH PATIENT CHOICES AND INDIVIDUAL CLINICAL JUDGEMENT (COX, 2005)
Best available evidence
Practitioner expertise
Client values & choices
Decision - Making
![Page 11: Widex Ireland ISHAA presentation](https://reader036.vdocuments.mx/reader036/viewer/2022070313/554bf376b4c9056b348b55e0/html5/thumbnails/11.jpg)
EVIDENCE BASED PRACTICE/ Evidence-based practice gives a sound foundation for decision making in
the audiological practice/ The approach is:
/ ONE HEARING PROBLEM AND ONE PATIENT AT A TIME.
/ 5 STEP PROCESS TO TACKLE ONE PROBLEM AT A TIME.

/ The Audibility Extender improves speech perception and production for children and adults with severe-to-profound high frequency hearing loss
/ Acclimatisation and training are essential for improvements in speech perception/production
/ Initial low preference for speech sounds
/ Progress in language scores and acceptance occur fast after targeted use of the Audibility Extender
/ Counselling is necessary to facilitate acceptance
/ Increase in confidence and self-esteem in school-aged children

/ Based on Speech Intelligibility Index (SII) optimisation
/ Ensures optimum SII in all listening environments
/ Speech is heard clearly under noisy conditions

MAIN FINDINGS FROM STUDIES
/ The Speech Enhancer can improve speech intelligibility in noise
/ The Speech Enhancer does not compromise listener comfort in noisy environments
/ Measurements of long-term average gain changes with the Speech Enhancer activated/deactivated confirm that the Speech Enhancer varies with SNR and hearing loss
![Page 41: Widex Ireland ISHAA presentation](https://reader036.vdocuments.mx/reader036/viewer/2022070313/554bf376b4c9056b348b55e0/html5/thumbnails/41.jpg)

ZEN/ Harmonic sound program
/ Based on fractal technology
/ Adjustable tempo and pitch
/ Six different zen styles for relaxation and concentration purposes
![Page 45: Widex Ireland ISHAA presentation](https://reader036.vdocuments.mx/reader036/viewer/2022070313/554bf376b4c9056b348b55e0/html5/thumbnails/45.jpg)
MAIN FINDINGS FROM STUDIES/ On average, 70% rated the Zen styles as relaxing
/ By adjusting the Zen tones to the preferences of the subjects, 86% found the fine tuned Zen style to be relaxing. The Zen tones can provide a relaxing listening background.
/ Helps a large portion of the hearing impaired population relax and concentrate.
/ Tinnitus sufferers, who are under double strain, rate the effects of tinnitus significantly milder after six months of daily Zen use
