Digital computers have proven themselves to be a useful tool in the solution of many scientific and engineering problems. To date, however, its use in the solution of electroacoustic problems has been very limited. A mathematical treatment of the equivalent electroacoustic networks often produces large systems of complex simultaneous equations which are time‐consuming to solve by hand‐calculations. As a result, the average electroacoustical engineer has developed a “feel” for the analog approach in preference to the classical methods. The ready facility of digital computers to perform innumerable arithmetic operations at high speed and without mistakes makes it now feasible to revive classical methods as a useful engineering tool. In this paper we will discuss the use of a computer to (1) calculate the gain‐frequency characteristic of a transistorized audio amplifier, (2) to predict the low‐frequency response and sensitivity of proposed loudspeaker designs. and (3) as an aid to predict the acoustic load characteristic of proposed loudspeaker locations.
