The term 'hearing threshold' is widely used in both American and Brazilian medical and scientific contexts, particularly in audiology, occupational health, and hearing aid fitting. In Brazil, audiologists and otolaryngologists (otorrinolaringologistas) regularly conduct hearing threshold tests as part of standard hearing evaluations. The concept is important in occupational safety regulations in both countries, where exposure limits are set based on hearing threshold preservation.
