New application guide for DB HR Protection against noise

Practical application manual for DB HR Protection against noise

The Application Guide of the Basic Document of Protection against noise was born within the scope of Eduardo Institute of Construction Sciences Torroja under the collaboration agreement carried out between said Institute and the Ministry of Promotion within the strategy of this Ministry to generate a series of supporting documents that facilitate the application of the Basic Documents of the CTE.

Its purpose is to facilitate the practical application of the Basic Document DB HR Protection against noise from Technical Building Code , CTE. Contains DB HR interpretation criteria, comments and application examples made with the intended to serve as support for technicians who participate in the building process, whether in the drafting of construction projects construction, as in the execution and control of works, although not are familiar with proper acoustic concepts.

We must remember the data of the types of noises with which following scheme:

We can understand a little more in a general way from the guide of works and examples of reforms before a catalog with extensive useful information.

Essential points of the LOE before the CTE (Technical Building Code)

Within the habitability requirements, there is framed the basic requirement of “Protection against to noise” , which consists of limiting, within the buildings and under normal conditions of use, the risk of inconveniences or diseases that the noise can cause to the users as a consequence of the characteristics of their project, construction, use and maintenance.

Objectives of the DB HR Basic Document (Basic Protection Document against noise)

To give an adequate response to the basic requirement of protection against noise, in the elaboration of the DB HR have pursued , among others, the following objectives:

• Raise regulatory sound insulation levels in construction in response to a social demand widespread, adapting them to the European average
• Adequately contemplate the transmission mechanisms acoustics between rooms, including the transmission of noise by flanks, thus overcoming the deficiencies of the NBE-CA in the prediction of noise transmission between rooms.
• Limit reverberant noise in rooms such as classrooms and conference rooms, where it is necessary to get adequate levels of intelligibility, or canteens and restaurants, where you should suitably limit the noise of background.

The Law of Noise and the DB-HR

Within the national regulatory framework, in relation to the protection against noise in buildings and outside the LOE and the CTE, must necessarily cite the Law 37/2003 on Noise . Bliss Law is the transposition of the European Directive on Assessment and management of environmental noise and has as a basic objective the prevention, surveillance and reduction of environmental noise pollution produced by acoustic emitters of any kind.

The Noise Law has two complementary regulations what they are:

• RD 1513/2005, dated 16 December , which develops the Law 37/2003, of November 17, on Noise, regarding to the evaluation and management of environmental noise
• RD 1367/2007, dated 19 October , by which the Law is developed 37/2003, of November 17, on Noise, regarding to acoustic zoning, quality objectives and emissions acoustic.

The writing of DB HR has been coordinated with the writing of Law 37/2003, of November 17, on Noise and with its regulatory developments, regarding the protection of users regarding noise from outside and the facilities. To obtain a global vision, provides the schema:

…………………………………………

• Dcc – HR – Document with comments from the Ministry of Promotion with the December 23, 2016 version.
• GUIDE DB-HR – Application guide for DB HR Protection against noise with the December 2016 version. Contains 48 pages: Introduction, full section 1 and section 2 up to 2.1 Acoustic Insulation.
• GUIDE DB-HR – Application guide for DB HR Protection against noise. Contains 417 pages: Introduction, sections 1, 2, 3 and annexes.

All documents can be accessed from HERE.

At this point we must remember the article… « Acoustics manuals and tools. The DB noise calculation tool HR» Where we can identify more than 30 manuals and tools to complement our work and the article of exterior carpentry in PVC from HERE given its importance in the building envelope.
