Materials provide the functions of sound absorption, sound isolation, sound diffusion and vibration damping for various applications.  Significant advances of the material technologies allow us to have a better understanding of the prediction of the performance and the production of the acoustic materials in past decades.  This technical area aims to identify the most promising advanced technologies in the development of material science, manufacturing processes, structures, etc., which improve the design, production and performance of acoustic materials and metamaterials. Presentations can include, but not limited to, conceptual design, theoretical development and practical implementations.

This session covers all aspects of aerodynamically generated noise. Emphasis is given to topics associated with aircraft noise such as whole-aircraft noise predictions, community noise and noise quality. Also covered are topics related to turbomachinery noise, fan noise and aerofoil noise radiation. Papers dealing with the aerodynamic noise mechanisms and applications such as jet noise, automotive noise and wind turbine noise are also invited. This session also deals with passive and active methods for reducing aerodynamic noise.

With the increasing mechanization of buildings there are increasing demands from occupants for reduced noise and vibration levels. This session considers the measurement, prediction and control of noise and vibration inside buildings. The sources could be internal building equipment (e.g. lifts, washing machines), external noise and vibration activities or activities inside mixed-use buildings (e.g. gyms in multi-storey residential blocks).

We all are confronted with sound in our immediate environment: at work, while commuting, recreating, and at home. Every sound can be identified as pleasant, disturbing or unwanted. Unwanted and chronic sound can negatively affect our health and well-being. At extreme levels it leads to hearing damage, at lower levels annoyance, sleep-disturbance, disturbance of activities and stress may occur. There is also a risk of long-term cardiovascular effects and metabolic changes, and cognitive effects. The new WHO guideline values were based on exposure-annoyance relationships.  The effects of noise are a function of its characteristics as well as non-acoustic factors and health promoting effects by supporting recovery from stress. In particular, the social context influences how people perceive sound in their environment and how they can actively contribute to the design and planning of cities and thus to the quality of life. After an overview of current developments in the field, and of epidemiological evidence of the health effects, this group of sessions will address the policy impacts of the WHO noise guidelines, the effect of occupational exposure and hospital noise, standardization of measures and planning and building cities for a better quality of life with a special focus on sounds.

This theme area covers a range of topics in psychological acoustics. It also includes examination of relationships between psychological and physiological responses. Sound perception, models of perception of sound attribute strengths and their use in noise evaluation, as well as models of summative judgments of sounds and their relationship to perceived attributes are also part of this theme area. The influence of non-acoustic factors on perception of sound is part of this theme area. Both other sensory modalities (e.g., visual, haptic, vibratory, etc.) and other factors that influence sound perception (context, experience, etc.) are part of this theme area. This area has overlap with soundscapes, product sound quality, annoyance and other health effects (sleep disturbance, speech interference, task interference), and product design.

The recent trend of vehicle sound qualities for better impression are involving areas related to powertrain noise, tire-road noise, aerodynamics noise and other equipment noise such as electric motor noise, gear contact noise and so on. And the sound created for the confirmation of the finger touch of the push button, sound created for making sure winker is operating for examples are also the target of modification.

Current popular area for our interest exists for the quiet cars, namely, electric driven cars. The cars of this type are too quiet at the low speed driving and the sound is hard to recognize for the pedestrians.

We would like to expect as many subjects as possible to be involved for designers and the engineers who are responsible for developing products to help understand the current status.

Soundscape presents a paradigm shift from the conventional focus on noise control, emphasizing on a holistic and interdisciplinary approach to promote sustainable acoustic environment. Recently, with the advent of new technologies, soundscape approach has been attracting increasing attention across researchers, designers, and policy makers. This session covers a wide range of aspects relating to soundscape. The themes include environmental noise strategy, the uses of sound in architecture and urban planning, auralization, psychoacoustics, virtual or augmented reality in soundscape, and community involvement and soundscape assessments.

Theoretical, methodological, and empirical/application studies are welcome.

Our current subject on this topic is related to classic power-plant noise and vibration on one hand and recent hybrid car system and electric driven motor car system on the other.

The target is also related to the tire and road related noise and vibration as well. With respect to conventional engines, the areas will be covered from gasoline engine and Diesel power-plant. Those are to some extent different due to the difference of combustion mechanism. And there exists different difficulty to overcome current problems for improvement.

Aero dynamics noise is also important at high speed driving from the viewpoint of driver and guest inside the compartment on one hand and inhabitants outside on the other.
