| dc.description.abstract | Due to the urbanization and verticalization processes of cities, urban noise is
one of the main agents of pollution in large cities and is considered a public health
problem by the World Health Organization (WHO). In an attempt to minimize the effects
of urban noise, studies have been conducted to improve the understanding of facade
acoustics, in order to reduce the impact of environmental noise inside buildings. To
analyze this impact, ABNT NBR ISO 16283-3:2021 sets requirements for evaluating
the performance of facade systems in the field. This is a complex process that requires
careful placement of equipment - sound source and sound analyzer - and
consideration of all variables at the site that may influence the test, such as the design
and implementation of the building. Given the increasing use of augmented reality
technology and its advantages in various sectors, this work aims to explore the
feasibility of using Augmented Reality as an auxiliary tool for conducting acoustic tests
in the field, with emphasis on assisting in equipment placement. For this purpose, five
case studies were analyzed, in which the distance from the facade was measured in
two ways: manually (using dimensional equipment) and using the Augin augmented
reality app. The distance measurements were statistically analyzed using analysis of
variance (ANOVA). It was observed that it is not recommended to use only the Augin
app for the complete acoustic performance test, as it was not very accurate in terms of
the sound source position, which could result in not meeting the minimum distance
requirement specified in ABNT NBR ISO 16283-3:2021. However, augmented reality
allows for a preliminary analysis of any test location - using the geometry template and
a physical path of the Reference Tracker. This preview of the testing process is crucial
as it enables the identification and evaluation of potential sources that could affect the
test results. | en |
