REGULATIONS ON THE MOSTOF THEM I’m allowedto LEVELS NOISE IN MIDDLE In the WHICH PEOPLE WORK And 145/2004

Article 1.

These Regulations prescribe the maximum permitted noise levels in the environment where people work and stay.

Article 2.

The sizes for describing noise and the manner and conditions for measuring and determining these quantities are defined by the following standards:

HRN ISO 1996 -1 -2 –3, Acoustics – description, measurement and determination of environmental noise,

HRN ISO 9612, Acoustics – guidelines for measuring and determining noise exposure in the working environment,

HRN EN 60804, sound meters with integration and averaging.

Article 3.

Terms within the meaning of this Regulation shall have the following meaning:

Noise source is every machine, device, installation, plant, means of operation and transport, technological process, electroacoustic device for broadcasting music and speech, noisy activity of humans and animals and other acts from which sound is propagated. The sources of noise are considered to be wholes as immovable and mobile objects and open and closed spaces for sports, recreation, play, dance, performances, concerts, listening to music, etc.

A residence

space is any open and closed space in which people reside permanently or temporarily.

A workspace

is any open and closed space where people work.

The basic noise level

of L95 is the noise level that has been exceeded 95% of the measurement time.

An equivalent permanent leq noise

level is that level of constant noise that would have the same effect on a human as observed variable noise of the same duration.

Residual noise

is the total noise present in a place before there has been any change in the existing situation.

L
_maxnT
is the highest noise level during measurement standardized at an echo time of 0.5 s.

Rating level serves to assess compliance with permissible noise levels. This is any predicted or measured acoustic level to which adjustment has been added. It is denoted by the index R.

Adaptation

is any size added to the predicted or measured acoustic level for taking into account some noise characteristics:

– content of prominent tones, impulses, information (clearly recognizable speech, music or singing), deep tones (deep tones are considered to exist when the valued level of C exceeds by more than 20 dB permissible A-noise level),

– the time period of noise (day, night, time of day rest, working hours),

– types of noise sources (road, air, rail transport, industry).

Article 4

The provisions of this Regulation relating to the day shall also apply to the evening.

NOISE IN OUTDOOR Space

Article 5.

1. The maximum permitted rating levels of outdoor noise emissions are given in Table 1. this rule.Table 1

Zone	Purpose of space	Maximum allowed rating noise levels L RAeq in dB(A)
Noise
		for day(L day )	night(L night )
1.	Zone intended for rest, recovery and treatment	50	40
2.	Zone intended only
	housing and residence	55	40
3.	Mixed zone, predominantly
	residential purposes	55	45
4.	Mixed, predominantly business zone with housing	65	50
5.	Economic zone (manufacturing, industry, warehouses, services)	– On the border of construction particles within the zone – The noise can’t be… ziti 80 dB(A)
		– At the border of this zone, noise must not exceed the permissible levels of the zone with which it borders

2. The values listed in Table 1. this Regulation relate to the overall level of noise and emissions from all existing and planned noise sources combined.
3. Zones from Table 1. these Regulations are determined on the basis of physical planning documents.

Article 6.

For areas where the existing residual noise level is equal to or higher than the permissible level according to Table 1. from Article 5. Noise emissions resulting from newly designed, constructed or reconstructed or adapted buildings with associated noise sources shall not exceed the permitted levels set out in Table 1. Article 5 this Regulation, reduced by 5 dB(A).

For areas where the existing residual noise level is lower than the permissible level according to Table 1. Article 5 Noise emissions resulting from newly designed, reconstructed or adapted buildings with associated noise sources shall not increase existing noise levels by more than 1 dB(A).

Article 7.

Noise level from newly built structures of transport infrastructure including railway lines, state roads and county roads in settlements, which touch or intersect zones from the 1st, 2nd, 3. and 4 of Table 1, Article 5. of this Regulation, should be designed and built in such a way that the noise level at the border of the planned road corridor does not exceed the equivalent noise level of 65 dB(A) during the day and 50 dB(A) at night.

In the case of reconstruction or adaptation of transport infrastructure buildings which generate noise above the permitted level, the construction of the transport infrastructure shall be designed or reconstructed or adapted in such a way as to reduce the noise level to the permitted level referred to in paragraph 1. this article.

Exceptionally, in the case where, during the reconstruction or adaptation of transport infrastructure structures, it is impossible to reduce the noise level according to paragraph 2. By applying the usual technical measures for noise protection on similar buildings, the design should explain the reasons and demonstrate that all available and technically acceptable noise protection measures have been taken.

NOISE IN ENCLOSED LIVING SPACES

Article 9.

All new sources of noise in and outside the building together must not raise the existing noise level in the living rooms.

Noise protection measures in the case of new sources of noise pursuant to paragraph 1. this article, should be applied to these new sources of noise.

CONSTRUCTION SITE NOISE

Article 17

– Works in open space and on buildings

Regardless of the zone in Table 1. Article 5 during the daily period, the permitted equivalent noise level shall be 65 dB(A). In the period from 08.00 to 18.00 hours, an equivalent noise level of an additional 5 dB(A) is allowed to be exceeded.

When performing construction work at night, the equivalent noise level shall not exceed the values in Table 1. Article 5 this rule.

For construction sites within an economic zone (zone 5) referred to in Table 1 Article 5 the equivalent noise level shall not exceed the established values during the day and night period.

By way of derogation from paragraph 1, 2. and 3. of this Article, it is allowed to exceed the permissible noise levels by 10 dB(A), in the case if required by a technological process lasting up to a maximum of one (1) night, or two (2) days over a period of thirty (30) days.

On the case of exceptional exceedance of the permitted noise levels pursuant to paragraph 4. the contractor is obliged to notify the sanitary inspection in writing, and this case must also be entered in the construction log.

– For works in multi-user buildings other than those measures in paragraphs 1, 2, 3, 4. and 5. of this Article, additional criteria shall apply:

In buildings with sojourn rooms where one stays at night, works can be carried out exclusively during the day period.

The permitted equivalent noise levels in the residence premises of the apartments are 40 dB(A), whereby in the period between 08.00 and 18.00 hours it is allowed to exceed the permissible noise levels by 10 dB.
