Underwater Speech Examples

The following speech samples are recorded under water with microphones that were connected to swim googles. Here the idea was to used speech command such as "play", "stop", or "next/previos song" to control an MP3 player that is tipically weared on the backside of the head (kept to the head via the swim googles). The music signals are played either via waterproof headphones or bone-conduction loudspeakers (used in our case). Even a simple recognition scheme performed rather good for such "unusual" sounds.

New Lecture - Fundamentals of Acoustics

Starting this winter term the DSS group offers a new lecture entiteled "Fundamentals of Acoustcs". The lecture is given by Dr. Jan Abshagen (see picture). It will be a 3+1 lecture which takes place once a week. The lecture will cover the following topics:

  • fundamentals of vibrations,
  • theory of sound fields,
  • sound and systems,
  • transducers,
  • sound-structure interaction,
  • ship acoustics,
  • ...
