    • Are urban noise pollution levels decreasing? 

      Arana Burgui, Miguel Upna (Acoustical Society of America, 2010)   Artículo / Artikulua  OpenAccess
      The majority of acoustic impact studies developed over the last 50 years have used a similar acoustic parameter Leq, Ldn but the noise mapping methodology has been very uneven. The selection of the measurement points, ...
    • 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; Valencia Leoz, Ana; 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 ...
    • 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; Valencia Leoz, Ana (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 ...
    • 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 ...
    • Trailing edge serrations effect on the aerodynamic performance of wind turbines 

      Llorente, Elena (2019)   Tesis doctoral / Doktoretza tesia
      En esta tesis se analiza el impacto que tienen los dientes serrados, colocados en el borde de salida de las palas, en el comportamiento aerodinámico del aerogenerador en el que están instalados. Inicialmente se ha realizado ...
    • 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 ...
    • Zwicker's annoyance model implementation in a WASN node 

      Pastor Aparicio, Adolfo; López Ballester, Jesús; Segura García, Jaume; Felici Castell, Santiago; Arana Burgui, Miguel Upna (Sociedad Española de Acústica, 2019)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      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 ...
