Efeito da estimulação acústica contralateral nas medidas temporais das emissões otoacústicas
(CEFAC Saúde e Educação, 2009)
OBJETIVO: comparar o nível de resposta e o tempo de latência das emissões otoacústicas sem e com apresentação de ruído contralateral. MÉTODOS: foram avaliados 30 indivíduos, com idade entre 18 e 30 anos, sem queixas auditivas ...
A minimal model to understand the discrepancies between acoustic and electromagnetic emissions in fracturing processes
(IOP Publishing Ltd, 2021)
Despite their common origin, experiments show that acoustic and electromagnetic emissions evolve in different ways during the fracture processes of brittle materials. It is common to find peaks of acoustic activity without ...
