This study analyzes the effect of an equalizer-modulated auditory intervention on the asymmetry of interaural auditory perception in groups with different emotional states such as well-being, anxiety, depression and mixed anxiety-depression.


The present study follows a randomized, double-blind (investigator and outcome assessor), parallel and controlled design. The auditory intervention consisted of listening to classical music modulated by an equalizer for 30 minutes, 2 sessions a day separated by at least 3 hours, for 10 days (Monday to Friday for 2 weeks). Participants assigned to the control group are cited to the Health centre, but they do not received any intervention. These subjects follow the same evaluation and data collection process.

Once randomized, all participants will make a first control visit in which a pure-tone audiometry was carry out and completed the various psychiatric evaluation tests to classify into different groups: Goldberg Anxiety and Depression Scale (GADS), Hamilton Anxiety Rating Scale (HAM-A), Hamilton Depression Rating Scale (HAM-D), and Sociodemographic variables (age, gender, nationality, education, working status, noise exposure, use of ear protection, and present or past use of any analgesic, anxiolytic or antidepressant for longer than a week).

The study variables collected at 3 months were pure-tone audiometry (air conduction).
