Appendix A
The Table below indicates the Unit number, type, and assumed finished floor level.

The following predicted road traffic noise levels are shown: L10(18hour), maximum Leq(!hour) day,
and maximum Leq(| hour) night.

For rail traffic the predicted Lmax at the most exposed window of the most exposed facade has been
shown. For other facades or other windows the Lmax may be lower. This is certainly the case for
facades located away from the road and rail.

‘The Lmax can vary significantly at a facade, depending on whether or not intervening structures
(acoustic barriers, residences) obstruct direct line of sight.

The TNR for living rooms and bedrooms has been shown (for rail noise 6 dB(A) has been added to
the noise level reduction required), as well as the construction categories.

In terms of nomenclature for the duplexes (Unit Type Z4), “'F’ means the unit facing the road and
rail, “A” denotes the rear unit (located away from the road/rail), while “AF” means that both units are
more or less equally exposed to the noise from the road and rail.
