Three-dimensional analysis of a noise barrier using a quasi-periodic boundary element method.

The Journal of the Acoustical Society of America

Fard SM, Peters H, Kessissoglou N, Marburg S.
PMID: 26093402
J Acoust Soc Am. 2015 Jun;137(6):3107-14. doi: 10.1121/1.4921266.

Two-dimensional (2D) numerical models are often used to estimate the environmental noise attenuation of a roadside barrier. The prediction of noise barrier attenuation using a 2D boundary element model assumes an infinitely long barrier with constant cross section. However,...

Supersonic intensity and non-negative intensity for prediction of radiated sound.

The Journal of the Acoustical Society of America

Liu D, Peters H, Marburg S, Kessissoglou N.
PMID: 27250172
J Acoust Soc Am. 2016 May;139(5):2797. doi: 10.1121/1.4948567.

Two numerical methods to identify the surface areas of a vibrating structure that radiate sound are presented. The supersonic intensity identifies only the supersonic wave components of the sound field contributing to far-field radiated sound. The supersonic intensity is...

'Quod scripsi, scripsi.' The quality of the report of telephone consultations at Dutch out-of-hours centres.

OBJECTIVE: To assess the quality of the content of reports of telephone consultations at out-of-hours centres and to investigate to what extent the reports reflect the actual telephone consultation.DESIGN AND SETTING: Cross-sectional qualitative study; 17 out-of-hours centres in The...

Non-negative intensity and back-calculated non-negative intensity for analysis of directional structure-borne sound.

The Journal of the Acoustical Society of America

Liu D, Havránek Z, Marburg S, Peters H, Kessissoglou N.
PMID: 28764429
J Acoust Soc Am. 2017 Jul;142(1):117. doi: 10.1121/1.4990374.

Non-negative intensity (NNI) is an approach to identify the surface areas of a structure that contribute to sound power. NNI is evaluated in terms of the acoustic impedance matrix obtained directly at the structural surface and as such can...

The effect of a crosslinking chemical reaction on pattern formation in viscous fingering of miscible fluids in a Hele-Shaw cell.

Chaos (Woodbury, N.Y.)

Bunton PH, Tullier MP, Meiburg E, Pojman JA.
PMID: 29092415
Chaos. 2017 Oct;27(10):104614. doi: 10.1063/1.5001285.

Viscous fingering can occur in fluid motion whenever a high mobility fluid displaces a low mobility fluid in a Darcy type flow. When the mobility difference is primarily attributable to viscosity (e.g., flow between the two horizontal plates of...

Walking and postural balance in adults with severe short stature due to isolated GH deficiency.

Endocrine connections

Santana-Ribeiro AA, Moreira-Brasileiro GA, Aguiar-Oliveira MH, Salvatori R, Carvalho VO, Alvim-Pereira CK, Araújo-Daniel CR, Reis-Costa JG, Andrade-Guimarães AL, Oliveira-Santos AA, Vieira ER, Gois-Junior MB.
PMID: 30865930
Endocr Connect. 2019 Apr;8(4):416-424. doi: 10.1530/EC-19-0103.

OBJECTIVES: Walking and postural balance are extremely important to obtain food and to work. Both are critical for quality of life and ability to survive. While walking reflects musculoskeletal and cardiopulmonary systems, postural balance depends on body size, muscle...

Acoustic metamaterial capsule for reduction of stage machinery noise.

The Journal of the Acoustical Society of America

Melnikov A, Maeder M, Friedrich N, Pozhanka Y, Wollmann A, Scheffler M, Oberst S, Powell D, Marburg S.
PMID: 32237831
J Acoust Soc Am. 2020 Mar;147(3):1491. doi: 10.1121/10.0000857.

Noise mitigation of stage machinery can be quite demanding and requires innovative solutions. In this work, an acoustic metamaterial capsule is proposed to reduce the noise emission of several stage machinery drive trains, while still allowing the ventilation required...

Direct discrete complex image method for sound field evaluation above a non-locally reacting layer.

The Journal of the Acoustical Society of America

Eser M, Gurbuz C, Brandão E, Marburg S.
PMID: 34852590
J Acoust Soc Am. 2021 Nov;150(5):3509. doi: 10.1121/10.0007065.

Thin layers of porous media are widely adopted in sound absorption and noise control applications due to their compact arrangement. Particularly, porous media with low flow resistivity exhibit complex, non-local reaction behavior. Therefore, sound field prediction above these media...
