Abstract:

A system is described which permits the automatic sampling and digital recording of the filtered outputs from several transducers in the 13 octave bands from 16 to 100 cps. The signals are presented in digital form on a printed paper tape. Four transducers were used in this particular application, but the system described is flex ible, so that additional transducers may be used. For transducers having different sensitivities or responding to different dynamic parameters e.g., pressure or velocity a correction is required to obtain absolute levels. Author
