1. Absorption of Sound : On the effects of field interaction on absorber performance
Abstract : Environmental noise has for decades been a well known problem, especially in urban areas. As noise requirements for vehicles are sharpened, noise reducing concepts are needed in early design stages requiring accurate simulations to support the design. READ MORE

2. Sound Field Design for Transducer Array-Based Acoustic Levitation
Abstract : Acoustic levitation is a technique where sound waves are used to hold an object at a designated position, suspending it against other external forces and keeping it stable in the desired position. Transducer arrays are an arrangement of many loudspeaker elements, tuned such that the array creates a sound field that is too complicated for the individual elements to produce on their own.

3. Experimental Validation of a Phased Array Ultrasonic Testing Probe Model and Sound Field Optimization
Abstract : New manufacturing technologies are developed to facilitate flexible product designs and production processes. However, the quality of the final products should not be compromised, especially for safety prioritized industries, e.g. aerospace industry. READ MORE

4. Analysis of Acoustic Absorption with Extended Liner Reaction and Grazing Flow
Abstract : Acoustic absorbing liners are efficient and commonly used measures to reduce sound levels in many fields of application. The sound reducingperformance of the liners is dependent on the acoustic state, defined by e.g. the flow and sound field interacting with the liner. READ MORE

5. Sound for Multisensory Motion Simulators
Abstract : Interaction in a virtual reality environment often implies situations of illusory self-motion, like, for example, in flight or driving scenarios. Striving for pictorial realism, currently available motion simulators often exhibit relatively poor sound design. READ MORE
