Interpreters as professional listeners

This chapter investigates the auditory health risks faced by interpreters, whose professional activity requires prolonged exposure to sound via headphones. It provides an overview of the anatomical and physiological foundations of hearing, the acoustic principles relevant for the interpreting task, and the cognitive load associated with simultaneous listening and speaking. Particular emphasis is placed on hazards linked to poor sound quality, sudden volume peaks, high levels of audio compression, and continuous headphone use. These factors can contribute to auditory disorders such as noise-induced hearing loss, tinnitus, hyperacusis, and general listening fatigue. They can also produce extra-auditory effects, including both functional and organic disorders. The chapter reviews studies on interpreters and other professionals who intensively use headsets, such as call centre agents, and it also examines Italian legislation on occupational noise exposure, highlighting a lack of adequate protection for interpreters’ hearing. The chapter closes with evidence-based recommendations for auditory self-protection and prevention, including sound checks, audiometric monitoring, awareness of volume levels, and inclusion of sound quality clauses in service contracts. It argues for greater institutional awareness and calls for further research into the complex relationship between interpreting, hearing health, and working conditions.
