13. Automated Loudspeaker Polar Response Measurements Under Microcomputer Control

AES Convention: 65 Paper Number:1586
Publication Date: 1980-02-06 

An automatic polar response measurement and analysis system controlled by an industrial/small business grade microcomputer is described. A Z80 microprocessor based S100-buss computer (a Cromemco System 3) interfaced with a one-third octave realtime analyzer and remote controlled turntable is used to gather response spectra at different angles. The disk stored spectral data is subsequently analyzed to generate polar/frequency response curves and beamwidth/directivity data. This paper emphasizes the practical aspects and problems encountered in development of the system`s hardware and software.

Don’t worry about people stealing your ideas. If your ideas are any good, you’ll have to ram them down people’s throats.
