Re: Membrane damping and backplate distance
Author: Posted by Jürgen Breitlow - Neumann

The higher dampening comes from the friction in the airflow. When the membrane moves to the backplate the air is compressed an partially pressed into the holes in the backplate. The resistance of for the airflow depends on the viscosity, the distance to the 'next' hole and the distance between membrane and backplate. When the membrane moves back the airflow goes the way back flow resistance is the same. In flow physics this is known as the law of Hagen-Poiseuille.
