Efecto Preventivo de Ejercicios con Tubos de Resonancia en un Grupo Docente.

Multiple studies have determined the importance of voice in those professionals who use it as their main work tool. Within this group are announcers, call center agents, teachers, among others; this research will deepen the professors, these are found for several hours a day using their voice to transmit knowledge within the classroom, often in poor conditions for effective work performance. In addition, they are exposed to various environmental and organizational risk factors which predispose them and generate a diversity of laryngeal pathologies characteristic of their occupation. Participants belong to a voice conservation program. The design of pre-experimental, quantitative research, using pre-test and post-test in the same population, cross-sectional descriptive, under an epidemiological approach. A vocal self-perception survey was applied as a pre-test, in order to identify the perception that these professionals had about their vocal characteristics. After this, they performed a series of exercises with resonance tubes based on the Semi-Occluded Vocal Tract (TVSO) technique and finally, the vocal self-perception survey was reapplied as a post-test to determine the physiological effects and changes of these exercises on the acoustic parameters of voice and speech characteristics such as: intelligibility, naturalness and audibility; achieving an immediate therapeutic physiological effect and a subjective perception of improvement after therapy, generating a change in the vibratory pattern of your vocal folds, minimizing abuse and vocal misuse, creating awareness of the care that should be taken with the voice when Professionally used as the main tool of his work.
