Later years legislation and regulation
has put emphasize on the work of reducing indoor noise levels in Norwegian
dwellings down below certain limits. For some years the effort has lead to a
wide activity of performing sound insulation improvement, generating projecting
work for transportation infrastructure owners and acoustic consultants. The
majority of these efforts have been governed by the national institutes who are
the legally responsible for the major noise sources.
During the last year a group consisting
of “The Norwegian Public Roads
Administration”, “Jernbaneverket”, “Avinor”, “The Norwegian Defence Estate
Agency” and “The Norwegian Pollution Control Agency” has joined forces in
development of a new common data assisted tool for management of indoor noise
from road, rail and aircraft noise sources. The goal is to harmonize the
processes of registering building conditions, improvement of sound insulation, and reporting for
national statistics purposes. A building oriented noise database system, and a belonging user application are the two main
components of the tool. It is intended to replace the existing tools “VSTØY”
used for road traffic noise and “Støybygg” mainly used for aircraft and rail
traffic noise. The tool is featured with full 1/3 octave spectrum capabilities
and a spectral construction database from SINTEF Byggforsk. From the start it
will be closely related to the new road traffic noise mapping system “Norstøy”.
In addition it will have import features adapted to other commonly used systems
like NORTIM and Cadna A. Though the tool is intended for use by the noise
source owners and their consultants, it will be freely available to the public.
The paper and presentation at BNAM 2010
will explain the conceptual modeling structure of the new tool, its database
and its user interface.
