Characterization of combustion anomalies in a hydrogen-fueled 1.4 L commercial spark-ignition engine by means of in-cylinder pressure, block-engine vibration, and acoustic measurements
Abnormal combustion phenomena are among the main hurdles for the introduction of hydrogen in the transportation sector through the use of internal combustion engines (ICEs). For that reason the challenge is to guarantee ... -
An efficient algorithm for the evaluation of tonality and the determination of the tonal frequency according to IEC 61400-11
The terms of tonality and tonal audibility of the noise emitted by wind turbines are defined and described in the standard IEC 61400-11. The procedure for tonality assessment at different wind speeds based on the narrowband ... -
How much are people willing to pay for silence? A one and half bound DC CV estimate
Noise is a major urban problem that has not received much attention from environmental economists. In this paper we present an attempt to value a noise reduction program in a Spanish city. Contingent valuation has been ... -
Managing transportation externalities in the Pyrenees region: measuring the willingness-to-pay for road freight noise reduction using an experimental auction mechanism
The estimation of the noise impact caused by road freight transportation is critical to have acknowledgment of the ambiance pollution caused by road traffic crossing geographical areas containing important natural resources. ... -
Modelo de regresión de Cox de la pérdida auditiva en trabajadores expuestos a ruido y fluidos de mecanizado o humos metálicos
Fundamento. Los trabajos sobre pérdida auditiva laboral se han centrado clásicamente en el estudio del ruido como causa principal. En la rama del metal es muy común la presencia de contaminantes físicos y químicos. En ... -
Pricing and internalizing noise externalities in road freight transportation
People living close to main roads may suffer from the nuisance of traffic and noise pollution. This paper assesses the effect of full routing cost in vehicle routing decisions by internalizing the external cost ... -
Remote (250 km) fiber Bragg grating multiplexing system
We propose and demonstrate two ultra-long range fiber Bragg grating (FBG) sensor interrogation systems. In the first approach four FBGs are located 200 km from the monitoring station and a signal to noise ratio of 20 dB ... -
El ruido como factor de riesgo en los músicos.
El ruido en el sector musical es un riesgo grave. Está constantemente presente tanto en ensayos como en actuaciones y a pesar de que el músico es consciente de su presencia, en la mayoría ... -
Strategic noise map of a major road carried out with two environmental prediction software packages
The main objective of this study is to analyze the differences found in the results of noise mapping using two of the most popular software techniques for the prediction of environmental noise. The location selected ... -
Tutela de los derechos humanos frente al ruido
El ruido es una de las principales preocupaciones medioambientales, sanitarias y de orden público en las sociedades actuales. A pesar de la proliferación de vías para su protección, el paso decisivo en la lucha frente ... -
Wavelets como método de reducción de ruido para señales pulsadas de THz en sistemas TDS
(2020) Trabajo Fin de Grado/Gradu Amaierako LanaReducir el ruido es crítico en sistemas pulsados THz-TDS (terahertz time-domain spectroscopy), especialmente si son usados en equipos de metrología, ya que incrementa tanto su ancho de banda como su rango dinámico, ... -
Zwicker's annoyance model implementation in a WASN node
Wireless Acoustic Sensor Network (WASN) nodes for noise measurement and acoustic environment description is a common use in the environmental measurement within the Smart City. The implementation of the psycho-acoustic ...
