The introduction deals with the description of some achievements of the advanced Danish audiology, and the equipment corresponding to this, in the paedoaudiometric department in the State Hearing Centre in Odense. The author has examined groups of normally hearing children aged from 4 months to 12 years at this Centre. They were outpatient and mostly single examinations which is the most frequent routine method used at the Centre. The audiometric part deals with the results of examination with headphones, in the free field, using pure tones and with special filtred programmes, and of threshold values with and without sound localization. The situation, reaction, interest, cooperation and sound localizing power of the child during examination, and the results at the play-board and with a series of other equipment are the subject of the psychological part. The aim of the investigation was to obtain basic, normal data and information for the Centre to permit the assessment of audiograms in outpatient paedoaudiometric practice as normal or pathological. The results may perhaps be interesting and useful for purposes of comparison for other paedoaudiometric instituts.
