BNAM2014 - Scientific program

Invited keynote speakers:

Professor Trevor Cox, Salford, UK, "popularising acoustics".

While sound is important to everyone, acoustic engineering is a relatively unknown discipline. In this keynote, methods that have been used by the author to popularise acoustics will be outlined and critiqued. First, psychoacoustic experiments run via the Internet will be discussed. These allow the public to take part in scientific exploration as test subjects or as a citizen scientist. Drawing on experience from half a dozen popularist experiments that have reached hundreds of thousands of people, the secrets of successful engagement will be outlined. In addition, experienced gained from BBC Radio 4’s So You Want To Be A Scientist, will be drawn upon to discuss how the public can run experiments and become more than just test subjects. New digital technologies allow the public to participate in acoustic science by enabling them to record and upload sounds to the Internet. Two projects, one on soundscapes and another on sound tourism are drawn on as examples. A key audience to target with outreach work is school children. The talk will finish by discussing a number of projects that have engaged school children in acoustics, highlighting the problems of reaching teachers and pupils.

Trevor Cox is a Professor at the University of Salford where he teaches acoustic and audio engineering and do research in acoustics.

Linda Madalik, acoustic consultant, Estonia, "Historical overview of room acoustics design in Estonia".

A historical overview is given to point out most significant projects and buildings in Estonia during different periods. The choir stand in Tallinn Song Festival Grounds  (1960) is presented as the most important building among these, contribution of  acoustician Helmut Oruvee to this building and his other numerous projects are described. Origin of most important halls and their acoustical characteristics are briefly summarized. Sound system of new Nokia Concert Hall is introduced. An open question is posed: Does acoustics design in Estonia have specific features?

Jesper Hvass Schmidt, Odense University Hospital, "Health related effects in relation to noise exposure from wind turbines and other noise sources"

There is an increasing concern in the community that noise from large wind turbines lead to adverse health effects. Despite numerous complaints from neighbors to wind turbines, research done so far has not been able to document serious health problems in relation to wind turbine noise. Most research done has been using subjective questionnaires as estimates of health problems related to either distance from wind turbines or measured and calculated A-weighted noise levels. There is a lack of studies investigating objective health parameters in relation to other characteristic exposure parameters such as low frequency noise. Moreover, other “noise” sources such as traffic noise, music and industrial noise are also discussed to highlight some of the differences regarding noise exposure and health effects.

See list of all possible topicsTechnical sessions contains presentations on all fields of acoustics, e.g., Environmental Acoustics, Building and Room Acoustics, Electro-acoustics, Machinery Acoustics, Psychoacoustics, Instrumentation and measurement techniques, Musical Acoustics, General Acoustics
