3D compressible simulation of a muffler with pseudosound prediction levels
(Purdue University, 2016)
Conference lecture
Restricted access - publisher's policyThe main objective of this paper is to present a numerical resolution of a suction muffler configuration by using an in-house object oriented CFD & HT code TermoFluids (Lehmkuhl et al. 2007), able to handle tridimensional ... -
A measurement method to discriminate aircraft fly-over noise
(2010)
Conference report
Restricted access - publisher's policyCurrently aircraft noise monitoring systems use a mesh of single microphones distributed around an airport to continuously sample the noise level. This fact requires a manual process of aircraft noise event detection and ... -
A methodology for the calculation of the noise radiated by the rails and the tunnel structure in railway tunnels
(Sociedad Española de Acústica (SEA), 2019)
Conference report
Open AccessIn this paper, a robust and fast numerical methodology to compute re-radiated noise in underground railway tunnels is proposed. In this study, the noise analysis does not account for the noise radiation from the train ... -

A short survey for a thermo-ducted kitchen hood wasted heat self-powered
(ASME International, 2022-08-17)
Article
Restricted access - publisher's policyIn this note, a brief survey is given to the possibility for a thermo-ducted kitchen hood where exhaust fan or other mechanical devices are no longer needed, and then, in addition, no sound is generated. The aim of this ... -
Active control of sound transmission through an aperture in a thin wall
(2014)
Conference report
Open AccessThe reduction on sound transmission through an aperture by active means is theoretically investigated. The primary field is composed by a plane wave that arrives at a rectangular aperture placed in an infinite rigid thin ... -
Active noise control for open windows
(2021-08-01)
Article
Restricted access - publisher's policyOver the last decades, the applications of the active noise control system are broadened. In this study, the active noise control is modeled to reduce the noise pass through an open window. The objective is to define a ... -
Actuaciones contra el ruido de actividades de ocio
(2018)
Conference report
Restricted access - publisher's policyIn many cities can be found areas where there is a high concentration of local leisure activities and evening entertainment (music bars, nightclubs, restaurants…) that develop their activity in coexistence with the residential ... -
Aircraft noise-monitoring according to ISO 20906: evaluation of uncertainty derived from the human factors affecting event detection
(2012)
Article
Restricted access - publisher's policyOne of the most important issues in aircraft noise monitoring systems is the correct detection and marking of aircraft sound events through their measurement profiles, as this influences the reported results. In the recent ... -
Analytical simulations on active control of sound transmission through an aperture in a rectangular enclosure
(2014-03-01)
Article
Restricted access - publisher's policyThis paper uses an analytical model of sound transmission through an aperture for the study of the performance of an active control of sound inside the enclosure to prevent the transmission of sound through an aperture ... -
Automatic detection of alarm sounds in a noisy hospital environment using model and non-model based approaches
(2017-11-12)
Research report
Open AccessIn the noisy acoustic environment of a Neonatal Intensive Care Unit (NICU) there is a variety of alarms, which are frequently triggered by the biomedical equipment. In this paper different approaches for automatic detection ... -
Automatic detection of equipment alarms in a neonatal intensive care unit environment: a knowledge-based approach
(International Speech Communication Association (ISCA), 2015)
Conference report
Restricted access - publisher's policyAlarm sounds triggered by biomedical equipment play a key role in providing healthcare in a neonatal intensive care unit (NICU). This paper presents our work on automatic detection of acoustic alarms in a noisy NICU ... -
