Abstract:
In order to assess lfn properly it is necessary to have knowledge of lfn, of
the social impact and of the legal and juridical possibilities. In many cases
to what limit a certain level of lfn is acceptable is questioned. A quite
common aid to assess lfn are curves in which levels (dB's) are related to
frequencies (Hz). In cases in question hearing thresholds, degree of annoyance
and the used 'normal' A-weighted standards have to be regarded. In the
Netherlands there are some lfn-curves. This article elucidates how one of
those curves is constructed. The first development of that 'EPA-curve' took
place in 1998. Revised in 2011. Following those principles of construction
enable to fit lfn-curves to an acoustical climate one wishes to be admissible.
Examples of factors are: degree (percentage) of coverage, emphasis on
protection of certain people or on the living space, the A- and C-weighted
general limits, avoiding 'all' noise or even granting wishes about quietness.
