PROBLEM TO BE SOLVED: To smoothly enable a hearing test of a plurality of subjects so as to easily avoid crosstalk (interference) with the existing radio equipment.SOLUTION: The audiometer includes headphone parts 1-1 to 1-5 and response operation parts 2-1 to 2-5 of a plurality of sets D1 to D5, and a body part 3, and the body part 3 performs radio communication with the headphone parts 1-1 to 1-5, performs radio communication with the response operation parts 2-1 to 2-5 independently of the radio communication with the headphone parts 1-1 to 1-5, supplies a test sound output command to the headphone parts 1-1 to 1-5 to cause the headphone parts 1-1 to 1-5 to output test sound, and acquires operation information of subjects to the response operation parts 2-1 to 2-5. Then, the body part 3 performs radio communication with the headphone parts 1-1 to 1-5 and the response operation parts 2-1 to 2-5 of the plurality of sets D1 to D5 by a time division multiplex method.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】 既存の無線設備との間で混信(干渉)を回避しやすく複数の被験者の聴力検査を円滑に行えるようにする。【解決手段】 当該オージオメータは、複数セットD1~D5のヘッドホン部1-1~1-5および応答操作部2-1~2-5と、本体部3を備え、本体部3は、ヘッドホン部1-1~1-5との間で無線通信を行うとともに、ヘッドホン部1-1~1-5との間の無線通信とは独立して、応答操作部2-1~2-5との間で無線通信を行い、検査音出力指令をヘッドホン部1-1~1-5に供給しヘッドホン部1-1~1-5に検査音を出力させるとともに、応答操作部2-1~2-5に対する被験者の操作情報を取得する。そして、本体部3は、時分割多重化方式で、複数セットD1~D5のヘッドホン部1-1~1-5および応答操作部2-1~2-5との間で無線通信を行う。【選択図】 図1
