Updating the practical classes on acoustic safety

Abstract

Abstract The paper presents the development of learning technology on acoustic safety. The possibilities of automating the practical tasks to increase students’ readiness level in project and expert activities are noted. As the result of master’s degree students questioning the interest in effectively disinfected silencer designs was identified and difficulties with tuning such devices were revealed. For practical class on acoustic safety the practical task on noise control of the ventilation system was adjusted and the silencer algorithmic model that is invariant to its dimensions and configuration was created. The control group of master’s degree performing a project task have composed silencers for ventilation systems with wide main air ducts and required broadband noise reduction. The following was established in the control group: students tuning the transformable device acquired the skill of composing the silencers for specific ventilation systems; students discussing the developed silencers have noted an increase in their level of readiness for project and expert activities in the field of acoustic safety; automating the calculations ensures the complete the project task in full without additional costs of training time. The modernized practical lesson on acoustic safety can be recommended for usage.
