Experts from 29 European and 3 overseers countries participated ... -
The definition of the science of acoustics and its practical significance
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)For last 15 years the author investigates the history and implementation processes of the science of acoustics. First of all these questions of definition and practical significance were discussed and analysed in the ... -
The sound classification scheme of buildings as a Lithuanian regulation for protection against noise: 10 years usage experience
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)Different needs for quietness in working and living environment can be expressed by introducing classification scheme defined as a set of minimum two classes with different limit values for acoustical performance. One of ... -
Investigation of reverberation time in different purpose rooms
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)Good acoustical qualities are essential in spaces in which speech communication is important. Excessive background noise or reverberation in such spaces interferes with speech communication and thus presents negative ... -
Practical applications of floating constructions with mineral wool slabs on concrete base floor for tightened sound insulation
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)Impact and airborne sounds penetrating via separating floors between adjoined premises can be defined as the main annoying noise in multi-storey housings as well as in public residential buildings. Lithuanian regulations ... -
Detailed calculation method for aircraft noise mapping based on verified input data from measurements
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)Disadvantages of existing programs for aircraft noise calculation like INM and SOUNDPLAN are the following: lack in databases of valid noise and flight performance data for aircraft manufactured in CIS countries; usage by ... -
Noise climate in communities close to Madrid airport
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)This paper assesses the noise climate existing in some communities close to Madrid airport. The residents in these communities were complaining about the noise generated by the air traffic operating from the airport. Based ... -
Criteria for aircraft noise control around airports and their role in reaching the strategic goals in environmental protection from aviation impact
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)The extent of the noise problem is large. In the European Union countries about 40% of the population are exposed to road traffic noise with an equivalent sound pressure level exceeding 55 dB(A) daytime and 20% are exposed ... -
Statistics of subjective assessment of sound: detection of outliers and evaluation of their contribution
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)The subjective evaluation of noise perception plays an important role in decision making in many applications in the field of acoustics, such as the evaluation of noise perception (annoyance)in communities located near ... -
Draft of the guidance document of the Russian Federation on justification of sanitary protection zones around airports
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)Boundaries of the sanitary protection zones around airports are defined by calculation and proved by measurements for three factors mainly: local air quality, aircraft noise and electromagnetic fields. For all the factors ... -
Correlative analysis of noise propagation
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)Noise created by traffic is one of the major problems of environmental quality in Europe. It is related to an increasingly growing dissatisfaction of the public with the current situation. In most cities, noise increases, ... -
Interdependency analysis of current and future criteria and their limits for aircraft noise control in urban areas
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)Aviation in the 21st century contributes to climate change, noise and air pollution. Together with various social and economic problems, environmental issues have the potential to constrain the operation and growth of ... -
Increase and decrease of the noise radiated by high-Reynolds-number subsonic jets through plasma synthetic jet actuation
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)Since the discovery of the existence of largescale structures in high-Reynolds-number free shear flows [1] and their role in the radiation of noise to the far field [5], the control of their dynamics has been an important ... -
Experience of the National Aviation University in the application of active noise control in an aircraft cabin
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)This presentation is focused on the problem of noise reduction in the aircraft cabins including cockpits. The noise has an adverse effect on the crew first of all, since it is disturbing, tiring, and interferes with transfer ... -
On instability wave control in turbulent jets
(Abstracts of the International Conference “Acoustic climate inside and outside buildings”, 2014, 2014)The presentation is based on two main results obtained in the framework of international projects OPENAIR and Orinoco. Two considered effects are determined by control of large scale structures in the initial part of shear ... -
