ALL NIOSH MEASUREMENTS

1. DATASET MOTIVATION This dataset was created to collect empirical evidence of real-world noise pollution levels in different urban configurations within the Eixample district of Barcelona. The main objective is to establish a transparent, unedited comparative record of acoustic impacts between high-capacity roads (such as Carrer d'Aragó) and newly pedestrianized green axes (such as Carrer de Consell de Cent). The measurements were captured using the NIOSH Sound Level Meter. 2. ASSOCIATED RESEARCH / BACHELOR'S THESIS This dataset is strictly linked to and serves as the primary fieldwork appendix for the following Bachelor's Thesis: * Thesis Title: Noise Pollution: Causes, Consequences, and Solutions * Author: Gaetano Heliot * Academic Institution: Universitat Autònoma de Barcelona (UAB) * Course: Smart and Sustainable Cities Management * Academic Year: 2025-2026
