- ItemAcesso aberto (Open Access)Desempenho de idosos em um teste de fala na presença de ruído(Pró-Fono Produtos Especializados para Fonoaudiologia Ltda., 2008-09-01) Calais, Lucila Leal [UNIFESP]; Russo, Ieda Chaves Pacheco; Borges, Alda Christina Lopes de Carvalho [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Pontifícia Universidade Católica de São Paulo Departamento de Clínica Fonoaudiológica; Santa Casa de Misericórdia de São Paulo Faculdade de Ciências Médicas; Centro de Estudos dos Distúrbios da AudiçãoBACKGROUND: speech perception of elderly, in silence and in the presence of background noise. AIM: to characterize and compare the hearing abilities of elderly in a monaural speech perception test, in the presence and absence of background noise (Speech Discrimination Test - SDT and Speech Perception in Noise - SPIN). METHOD: Participants of this study were 55 subjects of both genders, 60 years old or above, distributed in two groups: Control Group (CG), constituted by elders with no hearing loss and Study Group (SG), constituted by elders with symmetrical sensorineural hearing loss. The SPIN test was used, initially with the presentation of a word list in silence and later in the presence of Speech Noise. RESULTS: no difference was observed between genders in the SDT and the SPIN test. Correlation with age was observed only in the SDT for SG. A significant difference was observed when comparing the performance of the groups in the SDT and SPIN test. Regarding the presence of substitutions in the articulation of words, it was observed that it occurred in both groups and was more frequent in SPIN test, especially for the SG. CONCLUSION: the presence of the noise during the production of speech sounds is disadvantageous for elders, independently of the presence of hearing loss, but having a higher impact for those with hearing loss problems.
- ItemAcesso aberto (Open Access)Efeito da prática musical no reconhecimento da fala no silêncio e no ruído(Pró-Fono Produtos Especializados para Fonoaudiologia Ltda., 2006-08-01) Soncini, Fabiana; Costa, Maristela Julio [UNIFESP]; Universidade Federal de Santa Maria; Universidade Federal de São Paulo (UNIFESP); Universidade Federal de Santa Maria Departamento de Otorrino-FonoaudiologiaBACKGROUND: auditory training improves the perception of complex acoustic signals as well as the perception of speech. AIM: to verify if auditory training, through the practice of music, has an influence on the ability to recognize speech in quiet and noisy situations. METHOD: participants of this study were 55 individuals, with no musical experience (non-musicians) and 45 professional musicians who had been playing at military bands for at least 5 years (musicians). All of the participants were male right-handed military volunteers, with normal hearing thresholds and with ages varying between 25 and 40 years. Using the Portuguese Sentence Lists (LSP) test, sentence recognition threshold was investigated in quiet (SRTQ) and in noise (SRTN). Based on the obtained data, the signal/noise ratio (S/N) was calculated. The sentences and noise (fixed to 65 dB HL) had a monoaural presentation using headphones. RESULTS: when comparing the performances of both groups, the statistical analysis pointed no significant difference between the mean values obtained for the SRTQ. However, a statistically significant difference was verified between the mean values obtained for the S/N ratio. CONCLUSION: in a quiet situation, musicians and non-musicians had similar performances. However, in the noise situation, musicians presented better performances, indicating that musical practice is an activity that improves the ability of speech recognition when in a noisy environment.
- ItemAcesso aberto (Open Access)Índice percentual de reconhecimento de sentenças no silêncio e no ruído: efeitos da aclimatização no indivíduo avaliado sem as próteses auditivas(CEFAC Saúde e Educação, 2010-10-01) Santos, Sinéia Neujahr Dos; Petry, Tiago; Costa, Maristela Julio [UNIFESP]; Universidade Federal de Santa Maria; Centro Universitário Feevale; Universidade Federal de São Paulo (UNIFESP)PURPOSE: to check the effect of acclimatization on sentence recognition in quiet environment and under noise, in new users of hearing aids, evaluated without their use, before and after the acclimatization period. METHODS: the study comprised 40 individuals, aged between 28 and 78year old with mild to moderate sensorineural hearing loss. They were starting the selection and adaptation process of hearing aids. The tests were conducted in three sessions, before the adaptation of hearing aids, fourteen days and three months later, respectively. they were applied to Portuguese Sentences Lists test (COSTA, 1997), in free field, in quiet environment and under noise, both in fixed 65 dB A intensity, in which we obtained the percentual indexes of sentences recognition in quiet environment (PISRQ) and under noise (PISRN). RESULTS: the mean values for PISRQ in the 1st, 2nd and 3rd sessions were, respectively, 65%; 72% e 83% dB A. The mean values of PISRN for the 1st, 2nd and 3rd sessions were 51%; 58% e 59% dB A, respectively. While comparing the results between sessions, there was a statistically significant difference for PISRQ between the 1st and 3rd e and between the 2nd and 3rd session, and for PISRN, between the 1st and 2nd e and between the 1st and 3rd session. CONCLUSION: the subjects improved their performance using hearing aids, even being evaluated without them, and this improvement may be related to the acclimatization effect.
- ItemAcesso aberto (Open Access)Non-flat audiograms in sensorineural hearing loss and speech perception(Faculdade de Medicina / USP, 2013-06-01) Andrade, Kelly Cristina Lira de; Menezes, Pedro de Lemos; Carnaúba, Aline Tenório Lins; Rodrigues, Renato Glauco de Sousa; Leal, Mariana de Carvalho; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de Pernambuco Fonoaudiologia; Universidade Estadual de Ciências da Saúde de Alagoas; Universidade Federal do Rio Grande Física; Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: The audibility thresholds for the sound frequency of 137 upward- and downward-sloping audiograms showing sensorineural hearing loss were selected and analyzed in conjunction with speech recognition thresholds obtained from individuals seen at a public otolaryngology clinic to determine which frequencies in slope audiograms best represent speech recognition thresholds. METHOD: The linear regression model and mean square error were used to determine the associations between the threshold values. RESULT: The mean square error identified larger errors when using thresholds of 500, 1000, and 2000 Hz than when using audibility thresholds of 500, 1000, 2000, and 4000 Hz. The linear regression model showed a higher correlation (91%) between the audiogram thresholds for frequencies of 500, 1000, 2000, and 4000 Hz than for the frequencies of 500, 1000, and 2000 Hz (88%). CONCLUSION: Frequencies of 500, 1000, 2000, and 4000 Hz were the most significant in predicting the speech recognition threshold.
