Amplified music with headphones and its implications on hearing health in teens.

OBJECTIVE: To analyze the habits and behavior of adolescents exposed to amplified music with headphones and its implications on their hearing health. METHODS: One hundred thirty-one high school students, aged 15 to 18 years were given a questionnaire containing closed questions regarding their habits and behavior related to personal stereos use. It is a descriptive cross-sectional study and used the Chi-square test. RESULTS: It was shown that 79% of young people make use of portable music devices, 61.83% have a habit of using them often, 34.35% have long periods of exposure, and 37.40% use them at high volume. In terms of symptoms, present were: difficulty concentrating 63.36%; the need to ask people to repeat what was said 64.12%; the need to increase the TV volume 43.51%; tinnitus 38.93%, excitability 38.93%; and 36.64% of teens say they are somewhat worried about losing their hearing through the use of personal stereos. For the preventive aspects, 90.84% believe that noise is part of society, 80.92% find it important to reduce noise pollution, 51.91% would like to know the influence of the noise/pollution, but 74.81% would not like to participate in projects with questions about hearing health. CONCLUSION: The youths in this study are making indiscriminate use of personal stereos with headphones, within a population at risk for hearing loss considering its habits. Hearing Health Promotion Programs are recommended for this population.

[Utilization of optical devices and equipments by students with visual impairment]. / Utilização de recursos ópticos e equipamentos por escolares com deficiência visual.

PURPOSE: To verify perceptions and conduct of students with visual impairment regarding devices and equipment utilized in schooling process. METHODS: A transversal descriptive study on a population of 12-year-old or older students in schooling process, affected by congenital or acquired visual impairment, inserted in the government teaching system of Campinas during the year 2000. An interview quiz, created based on an exploratory study was applied. RESULTS: A group of 26 students, 46% of them with low vision and 53.8% affected by blindness was obtained. Most of the students were from fundamental teaching courses (65.4%), studying in schools with classrooms provided with devices (73.1%). Among the resources used in reading and writing activities, 94.1% of the students reported they used the Braille system and 81.8% reported that the reading subject was dictated by a colleague. Most of the students with low vision wore glasses (91.7%), and 33.3% utilized a magnifying glass as optical devices. Among the non-optical devices, the most common were the environmental ones, getting closer to the blackboard (75.0%) and to the window (66.7%) for better lighting. CONCLUSIONS: It became evident that students with low vision eye-sight made use of devices meant for bearers of blindness, such as applying the Braille system. A reduced number of low vision students making use of optical and non-optical devices applicable to their problems were observed, indicating a probable unawareness of their visual potential and the appropriate devices to improve efficiency.
