Noise mapping has now become a common method to assess urban sound environments. Strategic maps such as the ones required by the Environmental Noise Directive give a good impression on the impact of human activities on the living environment. However, they do not include all available scientific knowledge with regard to the causal path that lead to unwanted or wanted effects of environmental sound on humans. In this contribution we will discuss the available scientific knowledge on perception of sound and proven and potential effects gathered either by psychophysical, epidemiological, or bio-monitoring methods. We will then explore the state of the art in embedding this knowledge in both modeling and monitoring the effects of environmental sound. A clear distinction is needed between impact of sound at home, in and around the dwelling, including the quiet side on the one hand and the public space on the other. Public space covers restorative environments such as tranquil parks but also tranquil routes, areas of cultural importance, and even commercial environments. Future developments related to smart cities, sensor networks, and research needs will be discussed.

The purpose of this talk is to present and discuss a range of in-situ and laboratory methods which can be used to measure the morphological characteristics of porous materials. In the case of foams and granular media used for noise control applications the most common of these characteristics are pore size and its distribution, porosity and pore connectivity. In the case of fibrous media, the most useful non-acoustical characteristics are the fibre size and packing density. In the case of outdoor surfaces such as gravel, sandy soils and agricultural land which can be partly saturated with water, it is of direct interest to measure remotely the degree of water saturation, hydraulic permeability and pore size gradient. In the case of materials with good physicochemical properties, it is of interest to determine their internal pore surface area, porosity and pore size scales. In this paper the existing and newly emerging acoustic characterisation methods are discussed in terms of their complexity, accuracy and sample requirements. The application of these methods relate to traditional needs to measure and predict the in-situ performance of noise control elements and outdoor surfaces, to ensure the quality control during material manufacturing process and to be able to measure non-invasively the micro- and nano-structure of porous media which is used in catalytic filters, electric capacitors and for gas storage.

The Italian Opera House (IOH) has been the most stable home for opera for about four cen-turies. In fact from the second half of XVII century to early XX century theaters in Italy were built with rings of boxes piled up and with a gallery on top: this design was exported in nearly every European capital during the XVIII century. Nowadays it can be estimated that, ranging from the smallest one (1000 m3) to the largest one (10.000 m3), more than 800 IOH are still active and spread all over the country. All these buildings need restoration, renovation and, in some cases, complete reconstruction as for Teatro Petruzzelli in Bari and "La Fenice" in Venice destroyed by the fire in 1991 and in 1996 respectively. These events deprived not only the cities of Bari and Venice, but the whole word, of masterpieces of architecture and acoustics and raised the idea and the awareness that the acoustics of historical spaces for opera and music is a cultural heritage which has to be investigated, protected and enhanced. From here the increasing interest in understanding the unique acoustics of IOH with his very special future of rings of boxes: the "palchetti". In this work the background for the box design will be outlined with reference to the motivations that led to adopt this solution and to the consequences for the acoustics. Some of the open research issues will be addressed too.

Wim van Keulen has 20 years of experience in the field of developing and applying noise-reducing pavements. He received bachelor degrees in psychology, theology, and law and bachelor, master, and PhD degrees in psychophysics. In 2003 he started VANKEULEN consultancy with the accent on noise-reducing pavements. He developed the majority of low-noise pavements in the Netherlands and published about 150 papers. He is visiting professor at a number of universities in the Netherlands and abroad. In collaboration with the Technical University of Delft he developed a very accurate model for tyre-road noise that is applied for the development of various kinds of pavements. He developed a number of measurement methods for low-noise pavements.

In various policies and local legislation it is stated that the noise levels from road systems have to diminish. In most cases, noise reduction at the source is preferred. In case of road traffic noise this requires the application of low-noise pavements. Low-noise pavements have proven to be very effective and efficient in reducing (annoyance from) road traffic noise. Not only do they reduce absolute noise levels, but, probably more important, their subjective impression is considered to be very positive and often seem to contradict the ob-jectively measured noise level reductions. Additionally, the durability of low-noise pave-ments is still a major problem, which limits their application significantly. From practice it has been shown that technological research alone is not sufficient to prolong their durability. A number of aspects from acoustics, psychology, policy and legal contracts facilitate the quest for durable noise-reducing pavements.

Numerical procedures, such as the finite element and boundary element methods, are known to be very suitable tools for the investigation of acoustic problems. It turned out, however, that early formulations of these methodologies are rather computer time consuming and therefore not used very often in practical applications. The contribution aims to give an overview of recent developments in the fields of FEM and BEM and of the resulting new possibilities to investigate real life problems in technical acoustics. In particular, the methodologies will be validated by representative measurements and some complex industrial applications will be discussed in detail. Finally, some future trends in modern computations and possible topics for further research will be addressed. All methods and developments treated in this contribution are introduced briefly and illustrated by examples which show how the approaches can be used and how accurate they are.

Approximately 21% of the children in the United States school system speak a language other than English at home, but are being taught in English at school. English is additionally being used more and more often as a common language in international settings, even though participants at these international events again are not native English speakers. How do adverse room acoustic environments, including higher background noise levels and longer reverberation times, impact English-as-a-Second-Language (ESL) talkers and listeners versus native English talkers and listeners? This presentation focuses on two recent studies at the University of Nebraska that investigate how assorted room acoustic conditions impact English speech comprehension of ESL persons versus native-English-speaking persons. In the first study, the talkers were all native-English-speakers, and speech comprehension results are compared between ESL listeners and native-English-speaking listeners. In the second study, the talkers were all native-Mandarin-speakers, presenting in English. Speech comprehension results are compared between three groups then: native-English-speaking listeners, native-Mandarin-speaking listeners, and ESL listeners whose native language is not Mandarin. Results indicate that high background noise levels (greater than 50 dBA) negatively impact all listening groups, but have a greater detrimental effect on ESL listeners. In terms of reverberation time, native English speaking listeners are more capable of coping with longer reverberation, but such adverse conditions do still produce lower speech comprehension by ESL listeners.
