Накратко на български

Методите за измерване на звукоизолацията при строителни елементи се анализират, като се сравняват физическите данни с усещането на хората за шум. Това помага за създаването на по-точни стандарти и по-ефективни материали за защита от шум в сградите.

Advanced physical-acoustic and psycho-acoustic diagnostic methods for innovation in building acoustics

The principal societal goal of the project is to contribute towards a better sound insulation by exploiting the consortium platform of state-of-the-art expertise. This is achieved by a methodology that consists of 5 work packages: (WP1) Improving the diagnostic methods for objective assessment of physical properties of buildings elements (ISO140). Accurate measurements are needed in order to adequately assess and compare the performances of sound insulation elements. This is mainly challenging for low frequencies, due to the non-homogeneous distribution of the sound pressure levels in the sending and receiving room of a test facility. In this project, different measurement methods are compared and new ones are developed and validated. (WP2) Involving subjective assessment of sound insulation to help propose a suitable single-number quantity (ISO 717). It is well known that due to physiological and psychological reasons, people's judgement of the sound insulation performance of a building element is more complex and depends on multiple aspects of the sound. Nevertheless, for the sake of pragmatical comparison of the sound insulation performance in practical situations, it is useful to have a single number rating for that performance. In this project. by performing a variety of listening tests, we are assessing the adequacy of the currently used single number ratings in terms of their consistency with people's subjective assessments, and we are trying to further fine-tune ratings for optimum adequacy. (WP3) Enabling sustainable product innovation based on improvements achieved in diagnostic methods. Besides their acoustic insulation insulation performance, there are several other aspects of building elements that need to be taken into account during the product development. Innovations of products that are beneficial for some aspects of the performance can be harmful for other aspects. Also, improvements of product features are only sustainable if those improvements are also appreciated by their users. Therefore, in this work package, we take a helicopter view on multiple aspects of building insulation elements, in order to see which innovations are compatible with all aspects, as well as which ones have most societal value. (WP4) Disseminating all relevant techniques and results via proper media and personal contacts to designers, architects, as well as ISO policy makers, so that the efforts are investments in this project find their way to society, improving the life of EU citizens.

Цел на проекта

As clearly stated in report no. 10/2014 ""Noise in Europe 2014"" by the European Environment Agency, noise pollution is a major environmental health problem in Europe, yet the lack of comparable common assessment methods causes significant inconsistencies in exposure estimates of people affected by noise. However, in the past few years building acoustics has been influenced by evolution issues in terms of new acoustics requirements focused on sound insulation at low frequencies (reflected in proposals in the ISO 140 family), and by improving the single-number quantities (ISO 717) which would correlate better with subjective perception of sounds transmitted through building structures.The proposed project aims at (1) improving the diagnostic methods for more precise determination of physical properties of building elements (ISO140), (2) involving subjective assessment of sound insulation to help propose a suitable single number quantity (ISO 717), and (3) enabling sustainable product innovation as the result of improved diagnostic methods.First and foremost, novel acoustic measuring techniques, specifically, Laser Scanning Vibrometry and acoustic cameras, will be applied for developing novel diagnostic procedures. Second, noise perception tests will be developed using advanced, full 3D sound field recreation techniques. Single number quantities will be proposed to reflect perceived annoyance by noise, with the extension to low-frequency range <100 Hz. Finally, these advancements will be used for innovative design of building elements with improved sound insulation.This will have a lasting impact on collaborating partners of the consortium, both on universities, whose task will be to implement the research findings in practical solutions connected to noise abatement for raising living comfort, and SMEs, who will gain knowledge for innovation in design of sound insulating building elements and learn new methods for a precise detection of sound insulation deficiencies""
