Audiometry database system using a local area network.

We linked several audiometers to a personal computer to implement a standard pure-tone audiometric database system using a local area network (LAN). The efficiency of data entry and retrieval was increased by taking advantage of a relational database. The following five programs were developed: automatic incorporation of hearing test data program, audiogram retrieval and display program, patient information incorporation program, data transmission program through LAN, and evaluation of results of tympanoplasty. Data obtained over ten years or more can be rapidly stored and retrieved in this system, making it easier to evaluate the patient's hearing after tympanoplasty.
