Anomaly detection for environmental noise monitoring
… preferred measure for continuous environmental noise monitoring over raw audio because accepted standards and devices exist, these data do not compromise voice privacy, and thus an octave-band sound meter can legally collect data in public. By setting up an experiment that continuously monitors …

Unattended acoustic sensor systems for noise monitoring in national parks
… such as speech recognition and environmental monitoring, online detection and classification of these transient events is required. This is even more crucial for applications such as environmental monitoring as it is often done at remote locations where it is unfeasible to set up a large, …

Developing a framework of non-fatal occupational injury surveillance for risk control in palm oil mills
… NFOI surveillance by using epidemiological data, noise exposure data and NFOI data among palm oil mills’ workers. A total of 420 respondents who assigned in operation and processing areas (OP) (n=333) and general or office workers (n=87) had voluntary participated in this research. A questionnaire …

Noise Characerization For Proposed UCF Phyiscal Science Building Sites.
Today's Advance Technology Facilities require low noise levels and increased noise monitoring. Ambient noise can interfere with the accuracy and precision of experiments and manufacturing processes. Therefore preconstruction site surveys are needed to develop strategies for mitigating noise. …

URBAN SEISMIC AMBIENT NOISE ANALYSIS: INNOVATIONS AND APPLICATIONS
Seismic ambient noise generated by human activities provides an opportunity to monitor aboveground human activities without intruding on privacy. However, extracting specific signals from noisy seismic noise is challenging. Seismic ambient noise also contains information about the underground …

An evaluation of noise reduction strategies at large commercial airports in the United States: A policy analysis and framework classification
<p>Noise pollution from aircraft, specifically in the vicinity of airports as aircraft takeoff and land, is a problem that has been shown to have negative impacts on the welfare of humans, animals, and the surrounding environment. The problem may only become worse as air travel increases for cargo …

Reduction of wind induced microphone noise using singular spectrum analysis technique
Wind induced noise in microphone signals is one of the major concerns of outdoor acoustic signal acquisition. It affects many field measurement and audio recording scenarios. Filtering such noise is known to be difficult due to its broadband and time varying nature. This thesis is presented in the …
