Manuals and tools in acoustics. New version of the DB HR noise calculation tool.
I can admit that the issue of noise and acoustic calculation is one of the most overlooked points in a project, perhaps due to its complexity, because it has always been in the shadow of isolation or due to the simple fact that it is not attractive when projecting a project. edifice.
Remember how many times we have mentioned … "You can't be in this place, the noise !! … I hear the neighbors, how badly isolated it is! … etc" ad nauseam.
In this case, and given the magnitude of the issue and given the new version of the DB HR Noise Calculation Tool we wanted to complement the information with different manuals and practical guides, as well as applications to be able to understand a little better the great forgotten of the works.
Acoustic manuals or guides for learning the characteristics:
- Noise Manual (ICARO - Good practice guide for projecting acoustic quality in buildings) … HERE.
- Environmental noise explained in a simple way … HERE.
- Acoustics for architecture…. HERE.
- Introductory guide to general acoustics … HERE.
- Introduction to architectural acoustics … HERE.
- Acoustics in installations … HERE.
Note: From the Arauacustica portal (HERE) You can access an infinity of manuals, articles and links on topics related to acoustics more aimed at large buildings to different videos to improve our understanding. Also interesting is the SEA (Spanish Acoustic Society) … HERE.
Free tools or applications to help us calculate acoustics projects:
- From PLADUR acoustic insulation calculation tool … HERE.
- From URSA different tools and applications in acoustics … HERE.
- From PLACO … HERE. (Online tool - at the bottom of the page)
- From CHOVA … HERE. (In theory it is free and good results, carried out in conjunction with the Polytechnic University of Valencia - Campus Gandia)
As data, let us remember how noise affects health:
From the Technical Code portal a reprogramming the previous acoustic application to improve it in different aspects that will help us to verify compliance with the most frequent cases of our projects or work before the Basic Document - DB HR .
For new construction, rehabilitation or existing buildings (More information to see all the corresponding regulations here). Calculations in acoustics in rooms, calculation of acoustic absorption and reverberation
As a starting point, the “multiplatform” has been improved. Incorporated improvements in the excellent catalog of typical construction elementsFor both new construction and existing buildings and adding new databases, the user can also add their own characterized solutions in order to reduce time. Other points of interest are usability, renewal in the selection of construction elements and joints, improvement in project work … etc.
Why isolate acoustically
Although here we could spend hours and hours talking about the real benefits and benefits of living a little quieter, what we are interested in is knowing the scale of noise to know how much is the maximum according to regulations and common rates:
Acoustic calculation
This article is full of manuals and different tools to be able to practice the pertinent acoustic calculations sensibly, but we would like to provide a general scheme that can clarify concepts and verify in a simple way:
The tool is free and free to facilitate the application of the DB HR General Option:
Note: Update of theCalculation tool of the Basic Document of protection against noise:
It is a reprogramming of the previous version of the calculation tool that turns it into a multiplatform computer application that can be run on MacOS, Windows and Linux operating systems. The application includes a user manual that shows in a simple way how to use it.
The tool incorporates the data from the Catalog of Constructive Elements and the user can add their own characterized solutions. New construction elements have also been added that may be common in existing buildings.
The usability of the tool has been considerably improved compared to previous versions, overcoming many of the limitations they presented. The introduction of new modes of selection of construction elements and connections, the grouping of calculation cases in projects, as well as the use of other database technologies, provide the new version with a substantial improvement in terms of ease of use.
The tool is free and free. Download it: (They are direct downloads)
This tool, which facilitates the application of the calculation method of the general option of the DB HR Protection against noise, of the CTE, has been developed through collaboration between the General Directorate of Architecture, Housing and Land of the Ministry of Development and the Institute of Construction Sciences Eduardo Torroja, CSIC.
Access to the application and all the documentation from HERE. In addition you can also access theNew DB HR application guide Noise protection.
