Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected to discover the auditory thresholds and auditory performance of the participants in speech situations with and without the use of hearing aids through the test of speech perception in silence and noise. It is expected to obtain answers on the level of satisfaction of the participants about the two products tested through the satisfaction questionnaires applied. | — |
Secondary
| Measure | Time frame |
|---|---|
| Discover patient satisfaction with the two tested sound amplification devices and compare them. To discover the performance of the users in the tests of speech perception (silence and noise) using the two technologies; Discover the quality and performance of the two technologies in the long term; Achieve a high-tech, low-cost hearing product for universal health care.;It is expected to conclude which hearing aids (analogue of WHO-Inc. Or the digital of the Brazilian market) will bring greater auditory benefit and greater satisfaction for the participants. | — |
