Hearing is one of the 5 senses humans own and it has a huge role in development and learning. Its impairment has significant consequences on communication, social and academic life and emotional status of a person. Aging is the most important risk factor for hearing loss (Moyer, 2012). World Health Organization estimates that 328 million adults have hearing loss greater than 40 dB in better hearing ear (WHO, 2017; 2013). Given that any type of hearing impairment could have significant consequences on communication, social and academic life and emotional status of a person, it is very important that it is discovered in time and treated adequately. There are numerous ways today how to discover hearing impairment. One of the methods how to discover hearing impairment as early as possible is screening, that is, defining the impact of hearing impairment on everyday life (Goff, 2013). Self-assesment of hearing and related social and emotional difficulties gives a subjective view on impairment. Hence, it is a recommended way of screening the hearing loss among adults and elderly. For this purpose, Hearing Self-assessment Quesstinaire is proposed in Croatia. Previous research has shown that this questionnaire has potential to be used as a screening tool for hearing impairment in adults, showing possible functional hearing difficulties in persons with hearing impairment (Bonetti, Vodanović, 2012). The goal of this research was to investigate USS sensitivity towards relation between functional hearing difficulties and the degree of hearing loss. Research sample was made of persons with hearing impariment who completed the questionnire. Collected data was analyzed descriptively and the questionnaire sensitivity was investigated with cluster analysis. Differences in total results between the clusters were tested with nonparametric Man-Whitney U Test. Analysis showed that the questionnaire has the ability to differentiate persons with different degree of hearing loss according to their impression of hearing difficulties and the socio-emotional consequences of heraing impairment.
