SPECTRAL-ANALYSIS OF SOUNDS PRODUCED BY M USICAL-INSTRUMENTS USED FORAUDIOLOGICAL SCREENING IN CHILDREN

Some time ago audiological screening in infants was mostly performed u sing muscial instruments or equivalents. The use of acoustic evoked po tentials and otoacoustic emissions changed the strategies of hearing a ssessment in newborns and infants, however, musical instruments are st ill in use. An adequate interpretation of screening results obtained w ith musical instruments necessitates a profound knowledge of frequenci es and intensities derived from these instruments. In this study spect ral analyses of sounds from these instruments were performed. The resu lts may be of value for those using muscial instruments as a tool for audiological screening. In addition, the results show that with some i nstruments intensities able to cause inner ear damage can be generated .
