To reduce their space requirement, quarter wavelength resonators are coiled up into a spiral to have the shape of flat cylinder. The practical implementation these is tested using 3D printing, laser cutting and machining. Numerical simulations impedance tube measurements first compared for normally incident plane wave excitation. This step allows evaluate effect resonator's inlet diameter, internal wall thickness, overall height as well its constitutive material. A series samples then...
The examination of skull sexual dimorphism has been the subject numerous morphologic and craniometric studies, but disadvantage these studies is that they are dependent on experience operator involve subjectivity. In 1996, a team from Taiwan refined methods enabling sex an individual to be determined using cephalometric plots made lateral teleradiography. To validate their work European population, 114 dry skulls (59 men 55 women) were examined. Cephalometric teleradiography with orthodontic...
An important dip in the sound transmission loss of curved panels occurs at ring frequency. The relevance using small-scale resonators to solve this issue is experimentally demonstrated on an aircraft sidewall panel. effect varying spatial distribution single frequency (including combination with a broadband soundproofing treatment), as well multi-frequency fixed studied. Large improvement measured under diffuse acoustic field excitation obtained around limited added mass and very small...
Abstract Digital image correlation, deflectometry and digital holography are some of the full-field optical measurement techniques that have matured in recent years. Their use vibroacoustic applications is gaining attention there a need for cataloging their performance order to provide, broad community users potential future users, quantitative qualitative evaluations these three approaches. This paper presents an experimental comparison methods context vibration measurements, along with...
Subjective individual experiences seem to indicate that odors may form strong connections with memories, especially those charged emotional significance. In the dental field, this could be case odorant eugenol, responsible for typical clinging odor impregnating office. The of eugenol evoke memories unpleasant and, therefore, negative feelings such as anxiety and fear, since eugenates (cements containing eugenol) are used in potentially painful restorative dentistry. This hypothesis was...
A technique to setup a simply supported rectangular plane panel for laboratory vibroacoustic tests is described and validated. For given fixed thin vertical supports, dimensionless parameter proposed size these supports following desired frequency precision compared theoretical eigenfrequencies of with such boundary conditions. numerical study confirms the potential this design parameter. Detailed instructions assembling adequate on rigid frame are then given. Finally, three cases which...
The main scope of this work is to study the effect embedding a periodic pattern inside porous material, in order passively improving its acoustic performance terms sound transmission loss. A contemplated application improvement classical aeronautical soundproofing packages. In reach goal, numerical models an package including patterns are implemented using finite element method and Transfer Matrix Method. Firstly, some proposed configurations experimentally tested, providing comparison...
Among the factors which could explain avoidance behavior toward dental care, typical clinging odor of office, due to eugenol, is investigated in this study. The hypothesis supported by well-known effects odorants may influence cognition, emotion, and behavior. association between eugenol fear anxiety be explained fact that eugenates (eugenol-containing cements) are often used potentially painful restorative dentistry on vital teeth. emotional impact odors two other products (menthol methyl...
Data visualization and visual storytelling are increasingly common terms when institutions scientists want to introduce people their research science through stories. Yet mostly teach train in the language of scientific journals, whereas dissemination calls for other forms communication. A new university course introducing such a form communication is proposed postgraduate students at Université de Sherbrooke since January 2020. Its main objective help develop general interest skills into...
This paper aims at developing an experimental method to characterize the vibroacoustic response of a panel diffuse acoustic field (DAF) excitation with different laboratory setup than those used in standards (i.e., coupled rooms). The proposed methodology is based on theoretical model DAF and measurement panel's sensitivity functions, which its wall plane waves. These functions can be estimated experimentally using variations reciprocity principle, are described present paper. principles...
This study aims at validating an experimental method for characterizing the vibration behavior of panels excited by a turbulent boundary layer (TBL) excitation as possible alternative to standard means like wind tunnels or in situ tests. The approach takes advantage explicit separation contribution from dynamic panel. Based on measurement deterministic transfer functions panel, called “sensitivity functions,” which are then combined with either measurements model wall-pressure fluctuations...
This letter proposes an experimental method to estimate the absorption coefficient of sound absorbing materials under a synthesized diffuse acoustic field in free-field conditions. Comparisons are made between experiments conducted with this approach, standard reverberant room method, and numerical simulations using transfer matrix method. With simple setup smaller samples than those required by standards, results obtained proposed approach do not exhibit non-physical trends provide...
Abstract This paper describes an approach for identifying the magnitude and location of both stationary transient mechanical loadings applied to a thin rectangular simply supported plate. Full‐field deflectometry measurements virtual fields method are used with local equilibrium equation plate in time domain solve force reconstruction problem, whereas previous work by authors this last frequency domain. As result, it is possible reconstruct load history addition location. Experimental...
Micro-perforated panel sound absorbers are widely used in noise control applications the fields of architectural acoustics and transport acoustics. Combining micro-perforated panels with other resonant or absorbing systems may broaden frequency range which they absorb while ensuring that large absorption values reached. In this work, a hybrid absorber combines coiled quarter wavelength tube is proposed. Series parallel configurations these two studied from analytical, numerical, experimental...
