A Preliminary Analysis of Tympanometric Parameters in a Local Multiethnic Population
Audiology Research, 2020 Background: Tympanometry is a routine clinical test ordered at the Department of Otolaryngology, Ear, Nose and Throat (ENT) at Changi General Hospital (CGH). In combination with the pure tone audiogram, tympanograms aid in the diagnostic value of various

Analysis of wideband tympanometry in Ménière’s disease
Brazilian Journal of Otorhinolaryngology, 2022 Introduction: Endolymphatic hydrops is the pathophysiological substrate of Ménière’s disease. The changes in the inner ear, transmitted to the middle ear through changes in the ossicular chain mobility, can be quantified by wideband tympanometry, through

Data-driven acoustic impedance inversion with reweighted L1 norm sparsity constraint
Frontiers in Earth Science, 2023 Acoustic impedance (AI) inversion is widely used in geophysics and reservoir prediction. But the traditional impedance inversion method cannot fully exploit the sparse characteristics of geological attributes. There are problems with multiplicity and low
