Time-domain impedance boundary condition modeling with the discontinuous Galerkin method for room acoustics simulations.

J Acoust Soc Am 2020 Apr;147(4):2534

Building Physics and Services, Department of the Built Environment, Eindhoven University of Technology, P.O. Box 513, 5600 MB Eindhoven, The Netherlands.

The time-domain nodal discontinuous Galerkin (TD-DG) method is emerging as a potential wave-based method for three-dimensional (3D) room acoustics modeling, where high-order accuracy in the low frequency range, geometrical flexibility, and accurate modeling of boundary conditions are of critical importance. This paper presents a formulation of broadband time-domain impedance boundary conditions (TDIBCs) of locally-reacting surfaces in the framework of the TD-DG method. The formulation is based on the approximation of the plane-wave reflection coefficient at normal incidence in the frequency domain using a sum of template rational functions, which can be directly transformed to the time-domain.

Modelling of a hydroacoustic projector to produce low frequency sound.

J Acoust Soc Am 2020 Apr;147(4):2682

Dhwani Laboratory, Department of Mechanical Engineering, Indian Institute of Technology Kanpur, Uttar Pradesh-208016, India.

Low frequency sound is useful in several underwater applications, including sonar, underwater communication, detection of mines, sonobuoys, detection of oil or gas deposits, etc. Hydroacoustic projectors help in generating such low frequency acoustic waves far more effectively than other devices. Even though there is sufficient information available on modelling of various components used in complex hydraulic devices, there is a significant dearth of literature pertaining to mathematical modelling of hydroacoustic projectors and relevant experimental data.

Simulation of bronchial airway acoustics in healthy and asthmatic subjects.

PLoS One 2020 10;15(2):e0228603. Epub 2020 Feb 10.

Dipartimento di Elettronica, Informazione e Bioingegneria, Politecnico di Milano, Milan, Italy.

The onset and development of many airway pathologies affect sound propagation throughout the respiratory system; changes in respiratory sounds are detected primarily by auscultation, which is highly skill dependent. The aim of the present study was to compare healthy and asthmatic pulmonary acoustics by applying a 1D model of wave propagation on CT-based patient-specific geometries. High-resolution CT lung images were acquired in five healthy volunteers and five asthmatic patients at total lung capacity (TLC) and functional residual capacity (FRC). Read More

Binaural processing and phonological awareness in Australian Indigenous children from the Northern Territory: A community based study.

Int J Pediatr Otorhinolaryngol 2020 Jan 5;128:109702. Epub 2019 Oct 5.

Department of Linguistics, Macquarie University, Sydney, Australia; HEARing Co-operative Research Centre, Melbourne and Sydney, Australia; ARC Centre for Excellence in Cognition and Its Disorders, Macquarie University, Sydney, Australia. Electronic address:

Objective: Research has found that otitis media (OM) is highly prevalent in Australian Indigenous children, and repeated bouts of OM is often associated with minimal-to-moderate hearing loss. However, what is not yet clear is the extent to which OM with hearing loss impacts auditory signal processing specifically, but also binaural listening, listening in noise, and the potential impact on phonological awareness (PA) - an important, emergent literacy skill. The goal of this study was to determine whether auditory abilities, especially binaural processing, were associated with PA in children from populations with a high incidence of OM, living in a remote Australian Indigenous community in the Northern Territory (NT).

Purpose Numerous studies are testimony to the pivotal role of multicomponent tympanometry in diagnosis and differential diagnosis of auditory pathologies, not only of the middle ear but also the inner ear. Repeated measurements using multicomponent tympanometry have been used as a measure for stapedial tendon preservation during middle ear surgeries. However, such applications would produce reliable results only when multicomponent tympanometry produces replicable results across sessions. Read More

Comparison of two microphone array geometries for surface impedance estimation.

J Acoust Soc Am 2019 Jul;146(1):501

Acoustic Technology, Department of Electrical Engineering, Technical University of Denmark (DTU), Building 352, DK-2800 Kongens Lyngby, Denmark.

This study examines the estimation of the surface impedance of an absorber with microphone arrays. Two array geometries are compared-a rigid spherical array and a double layer planar array. The impedance is estimated via reconstructing the sound field (pressure and particle velocity) on the absorber's surface, using a plane wave expansion. Read More

Cochlear involvement in patients with systemic autoimmune rheumatic diseases: a clinical and laboratory comparative study.

Eur Arch Otorhinolaryngol 2019 Sep 30;276(9):2419-2426. Epub 2019 May 30.

Department of Rheumatology, University Hospital of Ioannina, Ioannina, Greece.

Purpose: Inner ear involvement has been reported in systemic rheumatic disease while detection of cochlin-specific antibodies has been reported in patients with idiopatic sensorineural hearing loss, suggesting cochlin's strong link to autoimmune hearing loss. The aim of this cross-sectional study was to calculate the prevalence of sensorineural hearing loss (SNHL) in patients with systemic rheumatic diseases, and to investigate any potential correlation with human antibodies to cochlin.

Methods: Patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjogren's syndrome (SS) and systemic sclerosis (SSc) according to the criteria of American College of Rheumatology were included in the study. Read More

Department of Oral & Maxillofacial Surgery, SRM Dental College Ramapuram, Chennai.

Patients with cleft palate have a high incidence of otitis media (OM), which, even after palatal repair, can persist and lead to auditory dysfunction. We aimed to identify what predisposes such patients to develop OM and correlate it with auditory function. We designed a prospective case-control study of adults who had had their cleft palates repaired in childhood. Read More

Methods for preventing middle ear barotrauma in computer-controlled pressurization of monoplace hyperbaric chambers.

Undersea Hyperb Med 2019 Mar-Apr-May;46(2):107-116

Department of Biomedical Engineering, Yonsei University, Wonju, Korea.

Middle ear barotrauma (MEB), one of the side effects of hyperbaric oxygen (HBO2) therapy, sometimes cannot be directly diagnosed during the therapy itself. Instead, its incidence and degree are judged based on subjective statements made by patients when in conversation with medical staff regarding how they feel. To prevent MEB in practice, it is proposed that the tympanic membrane evaluation system and automatic control chamber developed in a previous study be applied as part of a prevention algorithm [16].
