The setup can be used both with or without airflow. A 3m long diffusing section can be added to the facility to reduce air velocity and minimize acoustic reflections back into the test section. The ...

The findings indicated that smaller geometrical elements can produce diffuse reflections, which are essential for creating a rich acoustic environment in large spaces like cathedrals[1].

A Japanese construction firm has developed a 3D speaker that raised over 530 million yen (about $3.4 million) through ...
