Abstract
Environmental noise can produce negative effects on people’s health
since it interferes with basic activities such as sleeping, resting,
studying and communicating. These effects depend not only on the
physical characteristics of the noise itself, but also on parameters
associated to each person and each environment. It is thus important
to study noise pollution from a quantitative point of view as well
as a from the point of view of the annoyance that it produces in
the population.We have conducted a social survey aiming to identify
the main sound sources, evaluate the annoyance and analyse the main
effects of noise on people. The survey was distributed to a sample
of people living approximately in the corners of an imaginary 250
m grid placed over the map of the city of Valladolid (Spain). The
same corners were used to perform in situ measurements for a noise
city map.There are two main purposes for this research work: (1)
we want to compare the objective noise measurements to the annoyance
reported by the people in order to find some kind of dose–effect
relationship, and (2) we want to analyse how the population of Valladolid
evaluates noise reduction from an economical and social point of
view.
