Working on a unique loudspeaker and amplifier switch box for high end users and scientific research. The switch box enables the user to choose between two speaker pairs and two amplifiers. It also comes with a level adjustment for each speaker pair and amplifier. This way one can switch between a high sensitivity speaker and a small bookshelf speaker with the same SPL. It is also possible to switch between sensitive valve amps, as the amps will always see a load when switching.

Possible Modes:

  • Speaker pair A/B
  • Amplifier C/D
  • Mixed Speaker/Amplifier A/B/C/D

                        Scientific blind tests can be made easily and reproducible!

The switch box also comes with an integrated sine and noise generator for customers without an audio analyzer. Level adjustments can be made very easy with a mobile phone.

 

Stay tuned!

Worked on a study of a helmet design for skydivers. Skydivers can fall quite fast in a typical range from 160km/h to more than 300km/h. The noise of the wind and mechanical strain can be quite high! Dimples, known from golf balls, can effectively reduce noise. A special dimple design with new linings showed, that noise can be reduced by more than 6dB in the critical frequency range of our ears! Special test equipment was built to measure both vibration and SPL inside the helmet with a kemar head.
