8. Further technological optimizations
In addition to the above choices, satisfactory performance also depends on a number of precautions: minimizing all causes of loss.

Reducing viscous losses: the first point in obtaining sufficient performance from a thermoacoustic machine is to reduce the acoustic impedance
of the regenerative stack, otherwise excessive speeds will generate prohibitive viscous losses. For example, when using standing waves, the stack should be positioned...
