“…Several studies reported fewer correlations of PTA and ASSR thresholds on the 0.5 kHz frequency (17,7,23) as well as on the 4kHz frequency (21). A possible explanation could be the type of stimulus modulation because instead of amplitude modulation or amplitude and frequency modulation (7,21) this study used the exponential amplitude modulation associated to the modulation of frequency.…”

“…In cases of sensorial hearing losses the thresholds determined by the ASSR has shown strong correlations with behavioral thresholds determined by the Visual Reinforcement Audiometry (VRA) and/or conditioned audiometry (6,11,12,13,14,15,16), as well as by the pure tone audiometry (PTA) (17,18,19,20,21). In what refers to the degree of sensorial hearing loss the studies show weaker correlations with the less severe losses (22,7,23,24).…”

Background: the auditory steady state response (ASSR) is an electrophysiological procedure that evaluates, at the same time, the hearing thresholds of both ears at various frequencies. This procedure reduces the time of testing and enables the stimulation of levels close to 125dB HL, characterizing residual hearing. Aim: to verify the applicability of the ASSR to determine the hearing thresholds in different levels of sensorineural hearing loss. Method: 48 individuals aged 7-30 years, with different levels of hearing loss were assessed. The Pure tone Audiometry (PTA) and the ASSR were carried out in following carrier frequencies 0.5; 1; 2 and 4k Hz. The carrier frequencies in the ASSR were modulated in amplitude and frequency, with multiple dicotic stimulation for mild and moderate hearing loss. Simple stimulation was used to test the other hearing deficit levels. Results: there was a significant association (p<0.01) between the thresholds obtained in the PTA and in the ASSR for all of the tested frequencies, especially for the severe levels. However, for some patients, the hearing loss level was overestimated in the ASSR. Conclusion: the ASSR can be used to estimate the PTA threshold; nevertheless, it should not be analyzed in an isolated way, but seen as a complementary procedure to the behavioral auditory assessment. Key Words: Auditory Evoked Potential; Steady-State; Audiometry; Sensorineural Hearing Loss. ResumoTema: a resposta auditiva de estado estável (RAEE) é um procedimento eletrofisiológico que permite avaliar ao mesmo tempo os limiares auditivos de várias freqüências em ambas às orelhas, reduzindo assim o tempo de teste, e permite estimular até níveis próximos a 125dB HL, caracterizando assim a audição residual. Objetivo: verificar a aplicabilidade da RAEE para determinar os limiares auditivos nos diferentes graus de perda auditiva neurossensorial coclear. Método: foram avaliados 48 indivíduos com idade entre sete e trinta anos e diferentes graus de perdas auditivas. A Audiometria Tonal Liminar (ATL) e a RAEE foram avaliadas nas seguintes freqüências portadoras, 0,5; 1; 2 e 4k Hz. As freqüências portadoras na RAEE foram moduladas em amplitude e freqüência, com estimulação múltipla e dicótica nas perdas auditivas de grau leve e moderado. Estimulação simples foi utilizada nos outros graus de perdas auditivas. Resultados: houve associação significante (p < 0,01) entre os limiares obtidos na ATL e RAEE para todas as freqüências testadas, principalmente para perdas auditivas de grau profundo. Contudo em alguns pacientes o grau da perda auditiva pode ser super-estimado. Conclusão: a RAEE pode ser utilizada para predizer os limiares auditivos da ATL, porém não deve ser analisada de forma isolada, mas de forma complementar a avaliação audiológica comportamental.

“…Previous studies have reported no correlation between auditory steady-state response threshold and behavioural threshold for these patients, [2][3][4] and have reported that auditory steady-state response thresholds range from 20 to 70 dB or more around the behavioural thresholds for this population. With such variability, a patient with a moderate hearing loss as determined by auditory steady-state response assessment could potentially have a normal behavioural threshold or a severe hearing loss, or any degree of loss between these two extremes.…”

“…Esta situación se explicaría por el modelo de activación más amplio en la membrana basilar, así como por el tiempo de viaje aumentado hacia la región apical de la cóclea, donde se detectan los sonidos graves. Además el ruido ambiental puede producir un efecto de enmascaramiento en las frecuencias más bajas 4,[25][26][27][28][29][30] . La frecuencia de modulación (Mf) también podría ser un factor que influye en la respuesta de PEAEE.…”

“…Esta similitud entre ambos umbrales concuerda con los altos índices de correlación descritos anteriormente para el mismo grupo y se corresponde con investigaciones previas 6,23,31 . En el grupo de normoyentes se observaron diferencias mayores que las planteadas por otros autores 20,24,29,33 . Esta discrepancia se puede argumentar por la limitación en el control del ruido ambiental al no realizar el examen de PEAEE en una cámara sonoamortiguada, variable que afectaría en mayor grado a sujetos con mejor nivel auditivo.…”

RESUMENIntroducción: Los potenciales evocados auditivos de estado estable (PEAEE) son respuestas cerebrales frente a estímulos auditivos continuos modulados en amplitud y/ o frecuencia (AM/FM). Este examen puede determinar objetivamente umbrales por frecuencia específica.Objetivo: Conocer el manejo y describir los resultados de la aplicación de los PEAEE en sujetos con distintos niveles auditivos.Material y método: Estudio exploratorio y transversal en sujetos de 10 a 30 años con audición normal o pérdida auditiva (55 oídos). El estímulo consistió en un tono puro (0,5, 1, 2 y 4 kHz) a 46 Hz AM/FM.Resultados: Se obtuvo alta correlación entre la audiometría y PEAEE, tanto en el promedio (r =0,980) como en cada frecuencia evaluada. Los umbrales de PEAEE fueron superiores a los audiométricos y la diferencia promedio fue 23 dB HL en normoyentes y 13 dB HL en hipoacúsicos.Conclusiones: Los umbrales de PEAEE en sujetos hipoacúsicos fueron más cercanos a los audiométricos que en normoyentes. Dada la alta correlación entre la audiometría y PEAEE, éste podría incorporarse en la evaluación clínica, siendo un complemento en la detección y estudio de patologías auditivas.Palabras clave: Potencial evocado auditivo de estado estable, frecuencia de modulación, umbral electrofisiológico de PEAEE, umbral audiométrico estimado.

Multiple Auditory Steady-State Responses in Children and Adults with Normal Hearing, Sensorineural Hearing Loss, or Auditory Neuropathy

Abstract: Multiple ASSRs may reliably predict the behavioral threshold in subjects with SNHL and may serve as a valuable objective measure for assessing the hearing threshold across different frequencies in candidates for cochlear implants and children with auditory neuropathy.
