Abstract

Worldwide, the increase in the number of the elderly is already a reality. In Brazil, this figure is becoming increasingly significant. In the Brazilian age pyramid, this gradual change is directing a different behavior in several areas and, therefore, new public policies for the elderly care are changing the national scene.With the emergence of new technologies in the area of Audiology, researchers have emphasized the importance of individualization in the approach of the hearing impaired needs.Specifically analyzing the audiological issues, starting with the diagnosis process for the detection of hearing loss, there is a concern in meeting those individual needs to make communication more effective, carrying out directed evaluations prior to the hearing aid (HA) fitting, so that all the elements necessary to a satisfactory adaptation are guaranteed.In spite of the numerous advances and the possibility of a greater scope of prescriptive methods, the studies that guide the individualized process of HA fitting in the hearing-impaired elderly individual are few. In this context, a more detailed study about the comparative aspects of the targets' values prescribed by the methods is necessary, correlating with the verification results, with the speech intelligibility index, and mainly with the individual characteristics of the elderly emphasized by the expectation and satisfaction with the use of amplification. Thus, the objective of this project is to establish a HA fitting protocol for the hearing impaired elderly individual considering the individual characteristics. This proposal will be carried out through the comparative analysis of the targets' values prescribed by methods DSL m [i/o] v5.0 and NAL NL2 in correlation with the analysis of the speech intelligibility index (SII) and speech perception in silence and noise and, afterwards, through the evaluation of the results.This study pursues a further guidance in working with the elderly population, in consonance with the patient-centered model considering individual needs, including listening expectations, instead of concentrating only on hearing thresholds and electroacoustic characteristics of electronic devices. A more complete perspective of the understanding of the use of techniques and technologies to favor the human side and increase efficiency. (AU)
