ABSTRACT:
An automatic acoustical testing system is described wherein a digital computer controller utilizing hard-wired program memory is used to control testing of acoustical devices, such tests being carried out by driving a device to be tested with audio sound generator means and processing the output of the device by circuit means that are under the control of the computer resulting in digital readouts of the device's output amplitude and purity as well as providing graphical representations thereof.
