摘要

As very often the young people are exposed to high sound levels at their leisure activities, dangerous for their hearing acuity, it is important to know exactly the sound immission during the participation in such entertainments which requires the use of suitable measurement techniques. The aim of this paper is to describe in detail the techniques especially implemented and equipments appropriately calibrated employed for measuring the sound immission levels during the principal recreational activities of two groups of adolescents: attendance to discotheques and use of walkman/discman, along four years. It was performed in the frame of an interdisciplinary longitudinal study on the hearing effects in adolescents by non-occupational noise exposure and its relationship with physical and psychosocial variables developed in Cordoba (Argentina). In the case of discotheques, besides the well-known dosimeter, a miniaturised measurement instruments chain powered with battery and transportable in a hidden way were used. The measurements of real ear levels by using walkman and/or discman were carried out with the aid of instrumental line - manikin-technique - complying standards IEC 60959 and 60711. The systems employed allowed adjusted descriptions to the real sound situations through statistical noise descriptors, frequency analysis, noise dose, etc. fulfilling with the required accuracy.
