A plea for opera being practised as political expression: a lecture on the creation of HAPPY HAPPY, an operatic song-cycle with party by Mathis Nitschke
While researching transducers I found the cheap products like Visaton etc., some new companies in the mid range and a new higher end company name Revolution Acoustics. To get an idea how those high end and mid range models perform, I bought them and made a test (I ruled out the cheap ones immediately). I would have loved to find a video like this on the internet while doing my research, so I decided to make one.
At the time, when I could still repair my car myself, I could recognize the condition of the car by the sound of the blinker relay. This click-clack was caused by an electromagnetic switching process. The relay is a mechanical component that wears out and changes its sound as the vehicle ages. The relay resinifies, the clacking becomes harder.
