This year's "Long Night of Research" was even a bigger success than last year!

The Acoustic Research Institute was presented under the motto: "What you see is what you hear."

Take a look at some pictures of the event!

6 different areas of current research of the Acoustics Research Institute was presented to the interested audience:

• Psychoacoustics: The field of acoustics investigates the interaction of acoustic emissions, humans and the environment. The pictures show the Director  of the Institute Werner Deutsch in conversation with our visitors.

• A specific application of psychoacoustics is the study of hearing with cochlear implants. An interactive presentation with graphic animations and simulations gave an audible acoustic impression of listening with such implants. They also showed how the localization of sound sources for cochlear implant makers work.
  • The Presentation of the Team Cochlear Implants.
    

• The acoustic phonetics deals with the phenomenon of language. Using examples from the Viennese, Albanian and West African Igbo linguistic vowel analysis was presented. Many visitors wanted to hear how the computer talks Viennese dialect. Visitors could also monitor effects arising from changes in the acoustic parameters of vowels with a Klatt synthesizer.

• The station of the numerical acoustics consisted of three parts: A three-dimensional model of the vocal tract illustrated the digital simulation of speech production. The formants and cross-coefficients were determined in real time and displayed on a monitor. The simulation of sound propagation in the field of traffic noise was presented on the basis of calculations of the noise effect of straight and curved noise barriers graphically and acoustically. The application of a beamformer (acoustic camera) with the possibilities of various priority-setting was shown the example of the measurement of sound radiation from train tracks. One of our colleagues played the musical saw to the sounds in real-time process based on a spectrogram demo shown staring at the monitor. Many children and their parents were astonished.

• The Working Group on Mathematics in acoustics, presented the mathematical basis of sound analysis, based on a time-frequency representation (similar to a music sheet of music was played). For the human ear is not discernible components were extracted and character frequency data is directly manipulated interactively. An ongoing study of the theory of Frame Multipliers and your applications explored in the theoretical and applied acoustics properties of certain operators. Besides the mathematical basis and the application has been demonstrated in computer programs.

• The implementation of the results of the multiplier project in the institute's own software S_Tools-STx was shown with a real-time filtering applications. The software mentioned above S_Tools-STx is the basis of research at the Acoustics Research Institute. The various functions of the program and its real-time analyzer were presented.
