Environmental noise has become, in recent decades, a serious problem for the health of the population. In the Master's Degree in Occupational Risk Prevention, the possible negative effects on the human being are studied as well as the possible solutions for the control of this annoying and unhealthy noise. Nowadays, it is worth mentioning the interest for the incorporation of acoustic resonators for noise control and noise filtering in its transmission stage. Given that the students' profile of the Master of Occupational Risk Prevention are not became familiar with physical phenomenology and, in their case, the mathematical formulation required for his understanding, the current computer tools can be of great help.

In this article, we present the modelling of the acoustic behaviour of quarter wavelength resonators and Helmholtz resonators using the finite element method (FEM). With these models, developed using the commercial tool COMSOL Multiphysics, students can visualize the physics phenomena involved in the resonators behaviour as well as the characteristics of the wave phenomena.

Thus, this paper describes a practical session of the subject 'Environmental Acoustics' focused on the characterization of resonators. The considered practice session carries out a new contextualization, where students take an active role in adjusting the learning process of their personal skills.

Different types of real resonators, isolated matrices or in 2D formation are loaded as support of teaching resources in digital format to the e-learning platform of the university (PoliformaT).

The development of this platform implemented in the UPV facilitates the use of these new teaching models that combine traditional on-site laboratory assignments with other learning assignments carried out autonomously online by students.
