Acoustic and psychoacoustic levels from an internal combustion engine fueled by hydrogen vs. gasoline
Whereas noise generated by road traffic is an important factor in urban pollution, little attention has been paid to this issue in the field of hydrogen-fueled vehicles. The objective of this study is to analyze the influence ... -
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 ... -
Experimental evaluation of distortion in amplitude modulation techniques for parametric loudspeakers
Parametric loudspeakers can generate a highly directional beam of sound, having applications in targeted audio delivery. Audible sound modulated into an ultrasonic carrier will get self-demodulated along the highly directive ... -
Influence of recording technology on the determination of binaural psychoacoustic indicators in soundscape investigations
The evaluation of soundscapes is mainly carried out through field surveys, using soundwalking methodologies. Through rating scales and annotation of comments, the experiences and expectations of the participants are ... -
Localization of sound sources in binaural reproduction of first and third order ambisonics
The use of higher-order ambisonics in spatial sound recordings makes it possible to increase the accuracy of recording information about the direction from which the sound comes to the listener. However, with binaural ... -

People exposed to traffic noise in european agglomerations from noise maps: a critical review
Two of the main objectives of the European Directive on environmental noise are, firstly, to unify acoustic indices for assessing environmental noise and, secondly, to standardize assessment methodologies. The ultimate ... -
Proyecto JAULAB, más allá del aula
El proyecto JAULAB surge desde el grupo de Acústica de la UPNA con el objetivo de, a través del arte, acercar el trabajo realizado en el Laboratorio de Acústica a espacios menos habituados al lenguaje científico y ... -
Simulación acústica de un evento singular en un entorno abierto: el Tribunal de las Aguas de la Huerta de Valencia
El Tribunal de las Aguas de la Huerta de Valencia, declarado Patrimonio Cultural Inmaterial de la Humanidad en 2009 por la UNESCO, es la más antigua institución de justicia existente en Europa. Cada jueves, bajo la gótica ... -
Sound scene recreator: herramienta para investigar la percepción de paisajes sonoros
Uno de los objetivos al analizar un paisaje sonoro es identificar sus componentes y su influencia en nuestra percepción del mismo. En esta comunicación se presenta una herramienta de software dedicada que facilita esta ... -
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 ... -
Subjective evaluation of the localization performance of the spherical wavelet format compared to ambisonics
A common goal of most spatial audio techniques is to reproduce the precise location and size of sound sources. Ambisonics is a well-established spatial audio technique that renders sound sources with increasing accuracy ... -
Uncertainties caused by source directivity in room-acoustic investigations
Although deviations in the measurement of acoustic parameters should be lower than the subjectively perceivable change in the corresponding parameter measured, this study reflects that directionality of sound sources could ... -
Variabilidad del promediado espacial de la reverberación y claridad en la catedral de Valencia
ISO 3382-1:2009 especifica los métodos de medición del tiempo de reverberación y de otros parámetros acústicos en salas de espectáculos, así como el método para evaluar los datos y presentar el informe de ensayo. Para ... -
Visualización de diferencias entre señales envolventes en formato ambisónico
Ambisonics es un formato de sonido de esfera completa en el que, en contraste con otros formatos envolventes, los canales no distribuyen la señal que alimenta a cada altavoz. Por ello, cuando se desea cuantificar diferencias ...
