Abstract: Some time ago audiological screening in infants was mostly performed using musical instruments or equivalents. The use of acoustic evoked potentials and oto-acoustic emissions changed the strategies of hearing assessment in newborns and infants, however, musical instruments are still in use. An adequate interpretation of screening results obtained with musical instruments necessitates a profound knowledge of frequencies and intensities derived from these instruments. In this study spectral analyses of sounds from these instruments were performed. The results may be of value for those using musical instruments as a tool for audiological screening. In addition, the results show that with some instruments intensities able to cause inner ear damage can be generated.
