“…We also investigated elementary auditory perception and found that none of the threshold and supra-threshold tests performed (i.e., GDT, AM, FM, DLI, PTA noise , FPT and DPT) di↵ered significantly between the groups. Our data replicates several findings that also did not find di↵erences between chronic tinnitus and control groups (Bureš et al, 2019;Gilani et al, 2013;Moon et al, 2015;Raj-Koziak et al, 2022;Zeng et al, 2020). In all of these previous studies, elementary auditory stimuli were neither matched nor close to the tinnitus frequency.…”

Background: Many individuals with chronic subjective tinnitus report significant problems in comprehending speech in adverse listening situations. A large body of studies has provided evidence to support the notion that deficits in speech-in-noise (SIN) are prevalent in the tinnitus population, while some studies have challenged these results. Notably, elemental auditory perception is usually only minimally or not impaired. In addition, deficits in cognitive functions, particularly executive functions, have also been observed in individuals with tinnitus.Methods: In order to investigate differences in SIN performance and executive functioning, 25 participants with tinnitus and 25 control participants, between 23 and 58 years of age, were examined. A large audiometric battery was used, including tests of peripheral and central hearing, ranging from threhold and supra-threshold tasks to complex speech tasks. Additionally, four cognitive tests were performed, primarily covering the area of executive functions. Tinnitometry and tinnitus-related questionnaires were assessed to complement sample description and allow for secondary analyses. The groups were case-matched for age, sex, education, and hearing loss. We hypothesized, that tinnitus participants score lower in SIN and executive function tasks compared to healthy controls, while no group differences in elementary audio tasks were expected.Results: Hypothesized considerable differences in speech perception under adverse listening conditions were found in the SIN task and also in the gated speech task, while there were no differences in the basic speech recognition threshold task. Other elementary auditory perception tasks did not differ between the two groups. The cognitive tests revealed clear deficits in interference susceptibility in the Stroop task, but not in the Flanker task. There were no differences in inhibition or working memory tasks.Conclusion: Our results clearly delineate differences between the tinnitus and the control group in two tests of speech intelligibility under complex listening conditions. Further, the poorer performance in a task of interference control in individuals with tinnitus points towards a reduced central executive control in tinnitus. Taken together, these novel corroborating evidence supports the view of a deficient central inhibiton system in healthy individuals with tinnitus. Hence, we present important contributions to the ongoing debate about the effects of tinnitus on comprehension in adverse listening situations.

“…These tests are used in part in audiological practice, for example, to determine central processing disorders in children (Balen et al, 2019). However, there is little literature on these tests in tinnitus, but some studies using similar tests to ours did not find any di↵erences (e.g., Gilani et al, 2013;Raj-Koziak et al, 2022).…”

“…As EOAs são produzidas pelas CCEs da cóclea como resultado de processos de feedback mecânico ativo não linear, que podem ser espontâneos ou evocados por sons (Kemp et al, 1990;Norton et al, 1990;Serra et al, 2015). Para a avaliação comportamental do processamento auditivo, os relatos da relação com zumbido tangencia ao fato que este afeta certos aspectos do processamento auditivo como resolução temporal, percepção da fala no ruído e discriminação de frequência (Diges et al, 2017;Jain & Sahoo, 2014;Raj-Koziak et al, 2022).…”

Objetivo: verificar a influência da audiometria de altas frequências (AAF), exame audiológico não contemplado nos diagnósticos convencionais, mas de grande importância na detecção precoce da perda auditiva, no diagnóstico e ou caracterização do zumbido. Bem como a relação do zumbido na proposta da avaliação audiológica com AAF. Métodos: realizou-se um rastreio bibliográfico em seis revistas científicas nacionais da fonoaudiologia e otorrinolaringologia, com vasta abrangência de indexações. Resultados: a partir da busca na literatura, foram identificadas 119 referências; sendo que a partir destas, foram examinados 66 resumos. Ao final da verificação dos artigos, apenas três estudos foram eleitos dentro dos critérios de inclusão. As amostras contemplavam sujeitos com queixa de zumbido e audição normal, disfunção temporomandibular e possível perda auditiva súbita. Foi possível observar que a metodologia dos estudos contemplava a avaliação da AAF e outros complementos, como emissões otoacústicas, acufenometria, avaliação comportamental do processamento auditivo e aplicação de questionários. Não foi possível identificar nos estudos uso de um protocolo estruturado de AAF, inclusive que referenciasse algum padrão de normalidade. Conclusão: Apesar de poucas publicações nessas revistas relacionados ao uso da AAF associado ao zumbido, os estudos apresentaram amostras de pacientes com zumbido que fazem jus a pluralidade deste sintoma, assim como a diversidade de avaliação auditiva voltada a pacientes com zumbido e normo-ouvintes.

“…The control group consisted of 20 healthy subjects (mean age = 30, SD = 10.7) with no tinnitus, hearing loss, and ear/health problems. The sample size used in the study was based on the G*power analysis 13 derived from the effect size in the previous study 14 on the 4 psychoacoustic measures in normal hearing individuals with and without tinnitus. For an effect size of 0.32, 14 and power of 0.51 at significance level ( P ) of .05, the sample size required was 42.…”

BACKGROUND: Tinnitus is a sound perceived in the ears or head without any external or internal sound source. It can be hypothesized that the auditory processing at the different levels of the auditory pathway and working memory may get affected due to the additional sound contributed by tinnitus. The objective of our study is to evaluate binaural processes and working memory capacity in individual with tinnitus having normal hearing sensitivity. Methods: The binaural interaction process was evaluated using the interaural time difference and interaural level difference. Similarly, the binaural integration process was assessed using the dichotic consonant-vowel test, and the working memory was assessed using the audio descending span test and Audio 2N-Back span test. Mann–Whitney U test was done to see the significant difference between the groups. Results: The Mann–Whitney U test showed significantly poorer interaural level difference scores in the tinnitus group. Also, dichotic consonant-vowel test scores and auditory working memory test scores were found to be significantly lower in individuals with tinnitus. Conclusion: The binaural processes, along with the working memory capacity, are found to be affected in an individual with tinnitus, which in turn may affect the speech perception ability of the individual.
