In comparing ceramics vs tantalums one of the oft cited disadvantages is the tendancy for ceramics to exhibit a piezoelectric (i.e. microphonic) effect. Old-school technicians talk about ceramic disk capacitors "singing along to the music" in audio circuits.
I am having great difficulties trying to quantify this effect. The closest I have is a Kemet paper.
So, is this effect still significant in modern X75/X5R capacitors (for example)? Does it vary by package size and manufacturer? What frequency range will cause problems? What sort of noise (microvolts? millivolts?) can be expected to be generated and at what frequencies?
Most papers discuss audio circuits, but primarily I am interest in applications with vibrations under 200Hz (sometimes much less).
