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 ... -
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 ... -
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 ... -
