Reduction of the occlusion effect induced by earplugs using quasi perfect broadband absorption
Autor: Kévin Carillo, Franck Sgard, Olivier Dazel, Olivier Doutres
Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-12 (2022)
Abstract Passive earplugs are used to prevent workers from noise-induced hearing loss. However, earplugs often induce an acoustic discomfort known as the occlusion effect. This phenomenon corresponds to an increased auditory perception of the bone-co

Numerical investigation of the effects of model and operator uncertainties on component-based transfer path analysis methods with substructuring applied to aircraft-like components
Autor: Simon Prenant, Thomas Padois, Thomas Dupont, Olivier Doutres
Publikováno v: INTER-NOISE and NOISE-CON Congress and Conference Proceedings. 265:3201-3208
Hydraulic pumps are considered to have a major contribution to the structure borne noise generated inside aircrafts. Methods such as Component-Based Transfer Path Analysis (CB-TPA) are promising tools for aircraft manufacturers to build internal proc

Morphologic clustering of earcanals using deep learning algorithm to design artificial ears dedicated to earplug attenuation measurement
Autor: Bastien Poissenot-Arrigoni, Chun Hong Law, Djamal Berbiche, Franck Sgard, Olivier Doutres
Publikováno v: The Journal of the Acoustical Society of America. 152:3155-3169
Designing earplugs adapted for the widest number of earcanals requires acoustical test fixtures (ATFs) geometrically representative of the population. Most existing ATFs are equipped with unique sized straight cylindrical earcanals, considered repres

Towards a practical methodology for assessment of the objective occlusion effect induced by earplugs
Autor: Hugo Saint-Gaudens, Hugues Nélisse, Franck Sgard, Olivier Doutres
Publikováno v: The Journal of the Acoustical Society of America. 151(6)
The occlusion effect (OE) occurs when the earcanal becomes occluded by an in-ear device, sometimes leading to discomforts experienced by the users due to the augmented perception of physiological noises, or to a distorted perception of one's own voic

Acoustic imaging with spherical microphone array and Kriging
Autor: Thomas Padois, Julien St-Jacques, Kévin Rouard, Nicolas Quaegebeur, François Grondin, Alain Berry, Hugues Nélisse, Franck Sgard, Olivier Doutres
Publikováno v: JASA Express Letters. 3:042801
Acoustic imaging can be performed using a spherical microphone array (SMA) and conventional beamforming (CBF) or spherical harmonic beamforming (SHB). At low frequencies, the mainlobe width depends on the SMA radius for CBF and on the order of the sp

On the influence of the middle ear on the sound pressure level generated in open and occluded earcanals under a bone-conducted stimulation
Autor: Kévin Carillo, Franck Sgard, Guillaume Ramadier, Olivier Doutres
Publikováno v: The Journal of the Acoustical Society of America. 153:A332-A332
The occlusion effect is an acoustic discomfort commonly encountered by earplugs’ users, which corresponds to the increased auditory perception of the bone-conducted sound mainly at low frequencies. This perception is accompanied by the augmentation

Objectivization of the occlusion effect induced by earplugs in laboratory conditions—Effect of earplug type, insertion depth and background noise levels
Autor: Hugo Saint-Gaudens, Hugues Nélisse, Franck Sgard, Olivier Doutres
Publikováno v: The Journal of the Acoustical Society of America. 153:A159-A159
Blocking the earcanal’s entrance with an earplug can lead users to experience discomforts, one being the occlusion effect (OE), typically described as a distorted perception of one’s own voice. This discomfort sometimes causes users to misuse or

Towards a Holistic Model Explaining Hearing Protection Device Use among Workers
Autor: Olivier Doutres, Jonathan Terroir, Caroline Jolly, Chantal Gauvin, Laurence Martin, Alessia Negrini
Publikováno v: International Journal of Environmental Research and Public Health; Volume 19; Issue 9; Pages: 5578
Offering hearing protection devices (HPDs) to workers exposed to hazardous noise is a noise control strategy often used to prevent noise-induced hearing loss (NIHL). However, HPDs are used incorrectly and inconsistently, which explains their limited
