“…This finding is similar to the result of another study, which showed no significant association between the two variables 23 . These findings can be explained by the fact that the test evaluates the lower brainstem, as this structure has fully matured within the first years of life, it is expected that after five years of age, all subjects are already within the normal range of function, with no response differences after this age.…”

Resumo: OBJETIVO: investigar os achados do teste Masking Level Difference com os resultados do reflexo acústico e a composição do sistema fonológico de crianças com transtorno fonológico, com o propósito de verificar se há associações que possam auxiliar a compreensão do processo de aquisição de linguagem atípica. MÉTODOS: estudo quantitativo, observacional e descritivo, desenvolvido por meio de levantamento secundário de um banco de dados, constituído de avaliações fonoaudiológicas de 110 crianças com transtorno fonológico, com idades entre 5 e 10 anos. Para a composição do corpus deste estudo o requisito utilizado foi a realização da timpanometria, com curva timpanométrica do tipo A (Jerger) e possuir avaliação do Masking Level Difference. RESULTADOS: dos dados de 110 crianças, 57 se enquadraram nestes requisitos, compondo a população deste estudo, sendo 42 do sexo masculino e 15 do sexo feminino. Destas 57 crianças, 23 (40,3%) apresentam resultado do Masking Level Difference normal e 34 (59,7%) apresentam resultado alterado. Não foi encontrada diferença estatística na relação entre o Masking Level Difference com as variáveis idade, sexo, grau de inteligibilidade de fala e o resultado do reflexo acústico contralateral e ipsilateral. Na relação entre a aquisição fonológica dos fonemas em onsetinicial e medial, foi encontrada significância estatística entre a não aquisição dos fonemas /s/ e /ʀ/ em onset inicial e /s/ e /z/ em onset medial com o resultado do teste alterado. CONCLUSÃO: outras habilidades do processamento auditivo, além da interação binaural, devem ser estudadas a fim de identificar a relação deste com o transtorno fonológico.

“…A comparison between 8 and 11 year old children showed a general improvement in performance with age, which is consistent with suggestions that neuromaturation of some portions of the auditory system may not be complete until age twelve or later [40,41]. A similar improvement in performance with age (from 6 -10 years) was reported by Willeford for his fixed 500 Hz low-pass filtered speech test [42].…”

Objective: One type of test commonly used to examine auditory processing disorders (APD) is the low-pass filtered speech test (LPFST), of which there are various versions. In LPFSTs, a monaural, low-redundancy speech sample is distorted by using filtering to modify its frequency content. Due to the richness of the neural pathways in the auditory system and the redundancy of acoustic information in spoken language, a normal listener is able to recognize speech even when parts of the signal are missing, whereas this ability is often impaired in listeners with APD. One limitation of the various versions of the LPFST is that they are carried out using a constant level of low-pass filtering (e.g. a fixed 1 kHz corner frequency) which makes them prone to ceiling and floor effects. The purpose of this study was to counter these effects by modifying the LPFST using a computer-based adaptive procedure, and to evaluate the performance of normal-hearing participants of varying ages on the test. Methods:In this preliminary study, 33 adults and 30 children (aged 8 to 11 years) with no known history of listening difficulties were tested. The University of Canterbury Adaptive Speech Test (UCAST) platform was used to administer a four-alternative forced-choice adaptive test that altered a low-pass filter (LPF) to track the corner frequency at which participants correctly identified a certain percentage of the word stimuli. Results: Findings on the University of Canterbury Adaptive Speech Test -FilteredWords (UCAST-FW) indicated a significant maturational effect. Adult participants performed significantly better on the UCAST-FW in comparison to the child participants. The UCAST-FW test was reliable over repeated administrations.Conclusions: An adaptive low-pass filtered speech test such as the UCAST-FW is sensitive to maturational changes in auditory processing ability.

“…Still, a differentiation between auditory, i.e., sensory perceptual and cognitive or linguistic disorders is an important issue (Fitzgibbons and Gordon-Salant 1996; Cacace and McFarland 1998), also because APD is not always accompanied by weak phonological awareness (Sharma et al 2006). All this points to the need to clearly differentiate APD from speech disorders, which necessitates the inclusion of nonlinguistic test material (Moore 2006;Moore et al 2011). The BSA recently introduced a new consensus on a working definition: "APD is characterized by poor perception of both speech and non-speech sounds."…”

“…Almost all auditory skills described by the ASHA or the British Society of Audiology (BSA) can be investigated using both speech and nonspeech stimuli. Among others, there are tests investigating (1) localization or in the broadest sense spatial hearing using noise bursts (Kühnle et al 2013) or speech (Cameron et al 2006a, b), (2) discrimination of simple sounds Moore et al 2011) or speech stimuli (Kraus et al 1996), and even (3) binaural interaction based on clicks (Gopal and Pierel 1999;Delb et al 2003) or speech sounds (Willeford 1985). If auditory processing is solely measured using speech sounds, then the criteria recently established by the BSA (2011) would not be met, namely that APD is characterized by poor perception of both speech and nonspeech sounds.…”

Auditory Processing Disorders with and without Central Auditory Discrimination Deficits

Auditory processing disorder (APD) is defined as a processing deficit in the auditory modality and spans multiple processes. To date, APD diagnosis is mostly based on the utilization of speech material. Adequate nonspeech tests that allow differentiation between an actual central hearing disorder and related disorders such as specific language impairments are still not adequately available. In the present study, 84 children between 6 and 17 years of age (clinical group), referred to three audiological centers for APD diagnosis, were evaluated with standard audiological tests and additional auditory discrimination tests. Latter tests assessed the processing of basic acoustic features at two different stages of the ascending central auditory system: (1) auditory brainstem processing was evaluated by quantifying interaural frequency, level, and signal duration discrimination (interaural tests). (2) Diencephalic/telencephalic processing was assessed by varying the same acoustic parameters (plus signals with sinusoidal amplitude modulation), but presenting the test signals in conjunction with noise pulses to the contralateral ear (dichotic signal/ noise tests). Data of children in the clinical group were referenced to normative data obtained from more than 300 normally developing healthy school children. The results in the audiological and the discrimination tests diverged widely. Of the 39 children that were diagnosed with APD in the audiological clinic, 30 had deficits in auditory performance. Even more alarming was the fact that of the 45 children with a negative APD diagnosis, 32 showed clear signs of a central hearing deficit. Based on these results, we suggest revising current diagnostic procedure to evaluate APD in order to more clearly differentiate between central auditory processing deficits and higher-order (cognitive and/or language) processing deficits.
