OBJETIVO: determinar curvas logoaudiométricas, utilizando o teste Listas de Sentenças em Português (LSP), em um grupo de indivíduos normo-ouvintes e um grupo de indivíduos com perda auditiva neurossensorial, e comparar os resultados obtidos nestes grupos. MÉTODOS: utilizou-se o teste Listas de Sentenças em Português (LSP) para determinar os Limiares de Detecção de Voz (LDV), Limiares de Reconhecimento de Sentenças no Silêncio (LRSS), e os Índices Percentuais Máximos de Reconhecimento de Sentenças no Silêncio (IPMRSS), em um grupo de indivíduos normo-ouvintes (grupo A) e um grupo de indivíduos com perda auditiva neurossensorial (grupo B). RESULTADOS: o grupo A foi composto por 19 indivíduos do sexo feminino e 11 do sexo masculino, com idades entre 18 e 40 anos. No grupo B, 15 indivíduos eram do sexo feminino e 14 eram do sexo masculino, com idades variando entre 23 e 81 anos. Para o grupo A, encontraram-se valores médios de 16,47 dB para o LDV; 23,77 dB para o LRSS e de 31,23 dB para o IPMRSS. Já no grupo B, os valores encontrados foram de 38,38 dB para o LDV; 50,35 dB para o LRSS e 59,65 dB para o IPMRSS. Na análise estatística, encontrou-se diferença estatisticamente significante entre os grupos. CONCLUSÃO: foram traçadas as curvas logoaudiométricas para os grupos estudados. Os dados permitem inferir que a cada 1 dB de variação, na intensidade de apresentação das sentenças, ocasionou uma mudança de 6,77% no reconhecimento de fala para os indivíduos normo-ouvintes e de 4,70% e no grupo de indivíduos com perda auditiva.

Introduction Speech tests such as logoaudiometry measure the ability to perceive and recognize oral sounds. The Speech Recognition Index (SRI) is one of the speech tests adopted in clinical routine; it uses standardized live voice and recorded speeches. The live voice speech method can be influenced by intra and interspeaker variability, as well as by regionalism variability, whereas recorded tests show consistency in their presentation. Objective Analyzing results of the SRI test applied to live voice and recorded speeches from Paraná State, in different Brazilian counties. Method The sample comprised 125 individuals, 25 from each county (Rio de Janeiro, Florianópolis, Porto Alegre, Salvador and Curitiba), from both sexes, in the age group 20 to 70 years; the SRI was applied in both techniques. Results The recorded speech method showed prevalence of hit improvement in Rio de Janeiro (40%), Salvador, Porto Alegre and Florianópolis (28%). Individuals from Salvador and Florianópolis subjected to the recorded speech method showed better results in the left ear. Individuals from Rio de Janeiro and Porto Alegre showed satisfactory results in both ears, whereas those from Curitiba did not show statistically significant difference between the left and the right ear. Conclusion The recorded CD application method showed prevalence of hit improvement (%) in the SRI responses in comparison to the live voice speech technique in most of the studied counties. According to the hit rate measured in the herein investigated counties, Rio de Janeiro showed the best results in the recorded speech method.

Purpose: To present and describe a new strategy and protocol for obtaining the Sentences Recognition Indexes (SRI), using the Lists of Phrases in Portuguese test (LPP), considering words in the analysis of responses; to analyze and compare the results using the previous and the new strategies by checking their applicability and suitability. Methods: To consider each word of the sentence, words were classified according to their importance: functional and content words, assigning them, respectively, two and one points. SRI were obtained in 33 normal hearing adults, and results were compared using the two strategies. Results: A new protocol was established. Each point corresponds to the following percentages in each list: 1B, 1.11%; 2B, 1.13%; 3B, 1.17%; 4B, 1.16%; 5B, 1.20%; and 6B, 1.11%. The median SRI obtained through usual and new strategies were, respectively, for the list 1B: 60 and 82.57%; 2B: 70 and 80.79%; 3B: 50 and 76.60%; 4B: 70 and 82.60%; 5B: 50 and 77.20%; and 6B: 60 and 82.14%. A significant difference was found when these strategies were compared. Conclusion: New strategy and protocol for evaluating the SRI were developed using the LPP test, considering each word of the sentence. When comparing the responses it was noticed that when considering each word in the sentence it is possible to scale, more detailed and less variability, the actual ability to recognize speech of each individual, the new strategy and protocol developed confirmed its applicability and suitability to assess Sentence Recognition Indexes in Quiet in individuals with hearing disorders in a specific listening condition.
