Regulations 2 and 6
NOISE INDICATORS 1. Definition of the day-evening-night level Lden The day-evening-night level Lden in decibels (dB) is defined by the following formula:

⎟ ⎟ ⎟ ⎟
⎠
⎞
⎜ ⎜ ⎜ ⎜
⎝
⎛ ++
++= 10 10L
10 5L
10 L nighteveningday
10*810*410*1224 1g101Lden
in which: - Lday is the A-weighted long-term average sound level as defined in
ISO 1996-2: 1987, determined over all the day periods of a year,
- Levening is the A-weighted long-term average sound level as defined
in ISO 1996-2: 1987, determined over all the evening periods of a year,
- Lnight is the A-weighted long-term average sound level as defined in
ISO 1996-2: 1987, determined over all the night periods of a year;
in which:
- the day is 12 hours, the evening four hours and the night eight
hours. The Competent Authority may shorten the evening period by one or two hours and lengthen the day and/or the night period accordingly, provided that this choice is the same for all the sources and that they provide the Commission with information on any systematic difference from the default option,
- the start of the day (and consequently the start of the evening
and the start of the night) shall be chosen by the Competent Authority (that choice shall be the same for noise from all sources); the default values are 07.00 to 19.00, 19.00 to 23.00 and 23.00 to 07.00 local time,
- a year is a relevant year as regards the emission of sound and
an average year as regards the meteorological circumstances;
Environment ENVIRONMENTAL (ASSESSMENT AND MANAGEMENT OF
NOISE) REGULATIONS 2006

2005-27 Subsidiary 2006/121and in which:
- the incident sound is considered, which means that no account
is taken of the sound that is reflected at the façade of the dwelling under consideration (as a general rule, this implies a 3 dB correction in case of measurement).
The height of the Lden assessment point depends on the application:
- in the case of computation for the purpose of strategic noise
mapping in relation to noise exposure in and near buildings, the assessment points must be 4,0 ± 0,2 m (3,8 to 4,2 m) above the ground and at the most exposed façade; for this purpose, the most exposed façade will be the external wall facing onto and nearest to the specific noise source; for other purposes other choices may be made,
- in the case of measurement for the purpose of strategic noise
mapping in relation to noise exposure in and near buildings, other heights may be chosen, but they must never be less than 1,5 m above the ground, and results should be corrected in accordance with an equivalent height of 4 m,
- for other purposes such as acoustical planning and noise
zoning other heights may be chosen, but they must never be less than 1,5 m above the ground, for example for:

- the design of local measures meant to reduce the noise impact on specific dwellings,
- the detailed noise mapping of a limited area, showing
the noise exposure of individual dwellings.

NOISE) REGULATIONS 2006

2005-27 Subsidiary 2006/121 2. Definition of the night-time noise indicator
The night-time noise indicator Lnight is the A-weighted long-term average sound level as defined in ISO 1996-2: 1987, determined over all the night periods of a year; in which:
- the night is eight hours as defined in paragraph 1, - a year is a relevant year as regards the emission of sound and
an average year as regards the meteorological circumstances, as defined in paragraph 1,
- the incident sound is considered, as laid down in paragraph 1, - the assessment point is the same as for Lden.
3. Supplementary noise indicators In some cases, in addition to Lden and Lnight, and where appropriate Lday and Levening, it may be advantageous to use special noise indicators and related limit values. Some examples are given below:
- the noise source under consideration operates only for a small
proportion of the time (for example, less than 20 % of the time over the total of the day periods in a year, the total of the evening periods in a year, or the total of the night periods in a year),
- the average number of noise events in one or more of the
periods is very low (for example, less than one noise event an hour; a noise event could be defined as a noise that lasts less than five minutes;
- the low-frequency content of the noise is strong, - LAmax, or SEL (sound exposure level) for night period
protection in the case of noise peaks, - extra protection at the weekend or a specific part of the year, - extra protection of the day period, - extra protection of the evening period, - a combination of noises from different sources,

NOISE) REGULATIONS 2006

- the noise contains strong tonal components, - the noise has an impulsive character.

SCHEDULE 2 Regulation 7(2)
ASSESSMENT METHODS FOR HARMFUL EFFECTS
1. Dose-effect relations should be used to assess the effect of noise on populations. The dose-effect relations introduced by future revisions of this Schedule will concern in particular:
(a) the relation between annoyance and Lden for road and industrial
noise, (b) the relation between sleep disturbance and Lnight for road and
for industrial noise.
2. If necessary, specific dose-effect relations could be presented for:
(a) dwellings with special insulation against noise as defined in
Schedule 3, (b) dwellings with a quiet façade as defined in Schedule 3, (c) different climates/different cultures, (d) vulnerable groups of the population, (e) tonal industrial noise, (f) impulsive industrial noise and other special cases.
