Listas de monossílabos para teste logoaudiométrico: validação de construto

Abstract

Introduction: Speech stimuli are used as part of basic audiological assessment for speech recognition analysis, and validated materials are required for this purpose. Purpose: To perform construct validation of new lists of monosyllables for speech audiometry assessment. Methods: The speech recognition percentage index was determined with two materials: two new lists of monosyllables, which were validated for content and considered to be equivalent, and the list of Pen and Mangabeira-Albernaz (1973), considered as the gold standard in the clinical routine of speech audiometry assessment in Brazil. The former were presented as recorded material and the latter, via monitored live voice, by the same speaker. Individuals living in the same city where the research was conducted and who had moderate to moderately severe hearing loss in at least one ear were selected from a database. Twenty right-handed subjects -aged between 18 and 44, with mixed or conductive and sensorineural hearing loss -participated in this research. The scores resulting from the application of these lists were correlated. Data were analyzed by ear; there was a total of 18 right ears and 18 left ears. Results: There was no statistically significant difference between the right and left ears. There was a strong correlation between the new lists previously developed for this research and the list of Pen and Mangabeira-Albernaz in different hearing loss groups. When comparing the pairs of resulting scores, there was also a strong linear correlation between the new lists and the list of Pen and MangabeiraAlbernaz. Conclusion: The new monosyllable lists were validated for the construct.

Descending audiometric configuration: tonal means, speech perception and audiological hearing disadvantage

“…For the SRI survey, the monosyllable word lists of Vaucher et al (19) , were presented at the individual's comfort level (from 25 to 40 dBHL above the tritone mean), in a digital recording, using a Toshiba CD player, coupled to the audiometer, duly calibrated, aiming at excluding the influence of the examiner and maintaining standardization among the subjects. To obtain the percentage of correct answers, 4% of each word repeated correctly was considered.…”

Avaliação audiológica

“…Estímulos de fala são usados como parte da avaliação audiológica básica durante a realização da logoaudiometria (audiometria vocal), por meio da detecção e reconhecimento da fala, contribuindo para a confirmação dos limiares tonais obtidos na audiometria (VAUCHER et al, 2017).…”

Configuração audiométrica descendente: médias tonais, percepção de fala e desvantagem auditiva

“…Para a pesquisa do IPRF, foram utilizadas as listas de palavras monossílabas de Vaucher et al (19) , apresentadas no nível de conforto do indivíduo (de 25 a 40 dBNA acima da média tritonal), em gravação digital, por meio de um aparelho de CD Player, marca Toshiba, acoplado ao audiômetro, devidamente calibrado, a fim de excluir a influência do examinador e manter a padronização entre os sujeitos. Para obtenção da porcentagem de acertos, considerou-se 4% a cada palavra repetida corretamente.…”
