Abstract : Two types of devices which may be used in producing pulse trains for pulse count audiometry are described. The electromechanical model, while simple to understand, has disadvantages such as adjustment problems and it porduces acoustic and electrical noise. The digital electronic model eliminates these problems and costs less to construct. The digital approach using integrated circuits offers unusual flexibility for interfacing audiometers with computing equipment. (Author)
