| Sumario: | Abstract:
The World Health Organization estimates that 1.1 billion young people worldwide could be at risk of hearing loss due to unsafe listening practices. When audiometry is still normal, a difficulty to discriminate speech in noise (SND) may be an initial symptom of hearing impairment.
The objective was to analyze the relationship between general music exposure (GME) and SND, in university students with normal hearing from Córdoba, Argentina, between the years 2015 and 2016.
A descriptive cross-sectional correlational study was carried out. Thirty-three university students between 18 and 25 years were included, with impedance within normal values and air hearing thresholds in the conventional range ≤ 21 dB HL. Those who were exposed to occupational noise were excluded.To evaluate the GME, the adapted version for Argentina of the questionnaire "Sound exposure in recreational activities'' was applied. The self-report of SND was evaluated through the question "How often do you have difficulty understanding speech in noisy environments?". The studies were carried out at CINTRA, CONICET-UTN. There was no conflict of interest and the research was approved by the ethics committee of the Hospital Nacional de Clínicas.
It was found that a 52% (n = 17) of the young people presented GME “Low-Medium” and 48% (n = 16) “High”. A 58% (n = 19) reported a SND “with difficulty” and 42% (n = 14) “without difficulty”. A 62.5% (n = 10) of the total of young people who presented a “high” GME reported difficulties in the SND. On the other hand, only 35.2% (n = 6) of the young people who presented a “low-medium” GME reported difficulties in SND. Although empirically there seemed to be a relationship between the degree of GME and SND, the Chi Square test it was not statistically significant (p = 0.5787). In future work, it would be interesting to study SND with specific audiological tests in addition to self-reporting, to strengthen the analysis of the relationship between GME and SND.
