  The paper presents an approach to the verification of noise prediction models in selected localization in the city of Gdansk. The experiments described include a comparison between environmentalmeasurement results performed in the terrain and the noise level prediction results. The NMPB-96 (Nouvelle Méthode de Prévision du Bruit) and Harmonoise models outcomes provide the subject ofthe analysis. The proposed solution of continuous...

  The results of long-term continuous noise measurements in two selected schools are presented in the paper. Noise characteristics were measured continuously there for approximately 16 months. Measurements started eight months prior to the acoustic treatment of the school corridors of both schools. An evaluation of the acoustic climates in both schools, before and after the acoustic treatment, was performed based on comparison of...

  Artykuł dotyczy porównania dwóch rodzajów oceny hałasu w aglomeracjigdańskiej. Pierwsza ocena została przygotowana na podstawie prognozy hałasu w oparciu o mapy stworzone metodami obliczeniowymi w roku 2007. Druga ocena bazuje na rzeczywistych danych pomiarowych zarejestrowanych przez system ciągłego monitoringu działającego w aglomeracji od 2008 roku. W artykule zaprezentowano i przeprowadzono analizy występujących różnic pomiędzy...
