Abstract
Numerical modelling is of importance for the design, improvement
and study of acoustic transducers such as microphones and
accelerometers. Techniques like the boundary element method and
the finite element method are the most common supplement to the
traditional empirical and analytical approaches. However, there
are several difficulties to be addressed that are derived from the
size, internal structure and precision requirements that are
characteristic of these devices. One of them, the presence of very
close surfaces (e.g. the microphone diaphragm and back-electrode),
leads to machine precision errors and instabilities in the
computations of numerical solutions. An investigation to deal with
this narrow-gap problem has been carried out.
