    • An efficient algorithm for the evaluation of tonality and the determination of the tonal frequency according to IEC 61400-11 

      Arana Burgui, Miguel Upna; San Martín Murugarren, Ricardo Upna; Ezcurra Guisasola, María Amaya Upna; Valencia Leoz, Ana Upna; Llorente, Elena (Institute of Noise Control Engineering, 2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      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 

      San Martín Murugarren, Ricardo Upna; Tello, Pablo; Valencia Leoz, Ana Upna; Marzo Pérez, Asier Upna (MDPI, 2020)   Artículo / Artikulua  OpenAccess
      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 

      San Martín Murugarren, Ricardo Upna; Arana Burgui, Miguel Upna; Ezcurra Guisasola, María Amaya Upna; Valencia Leoz, Ana Upna (Institute of Noise Control Engineering, 2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      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 ...
    • People exposed to traffic noise in european agglomerations from noise maps: a critical review 

      Arana Burgui, Miguel Upna; San Martín Murugarren, Ricardo Upna; Salinas Hilburg, Juan Carlos (De Gruyter, 2014)   Artículo / Artikulua  OpenAccess
      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 ...
    • Strategic noise map of a major road carried out with two environmental prediction software packages 

      Arana Burgui, Miguel Upna; San Martín Murugarren, Ricardo Upna; San Martín Erviti, María Luisa Upna; Aramendía Santamaría, Emilio Upna (Springer Netherlands, 2010)   Artículo / Artikulua  OpenAccess
      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 ...
    • Uncertainties caused by source directivity in room-acoustic investigations 

      San Martín Murugarren, Ricardo Upna; Arana Burgui, Miguel Upna (Acoustical Society of America (ASA), 2008)   Artículo / Artikulua  OpenAccess
      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 ...
