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)
External 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 ... -
