    • Strategic noise map of a major road carried out with two environmental prediction software packages 

      Arana Burgui, Miguel Upna Orcid; San Martín Murugarren, Ricardo Upna Orcid; 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 ...
    • Are urban noise pollution levels decreasing? 

      Arana Burgui, Miguel Upna Orcid (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, ...
    • Uncertainties caused by source directivity in room-acoustic investigations 

      San Martín Murugarren, Ricardo Upna Orcid; Arana Burgui, Miguel Upna Orcid (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 ...
    • Aspectos biopsicológicos de la infección por virus inmunodeficiencia humana (VIH) 

      Aparicio Ágreda, María Lourdes Upna; Cuevas Jiménez, Carlos Pablo (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006)   Artículo / Artikulua  OpenAccess
      El objetivo de este artículo es ofrecer una comprensión global de la infección por VIH. Si bien es un proceso inicialmente asintomático, el avance de la infección produce consecuencias a nivel de funcionamiento, en gran ...
