Teaching the basics of acoustics using smartphones

This communication proposes a basis for offering short introductions to the basic principles in acoustics, like adding decibels and the behavior of Helmholtz or quarter-wavelength resonators. The proposed approach combine mobile and experiential learning approaches using smartphone sensors and applications. The objective of these mobile laboratories is to complement, but not replace, traditional laboratories, which allow for more advanced learning in particular topics. However, the proposed series of experiments can be carried out autonomously; students can explore scientific knowledge in real-life situations and without time or place constraints. Indeed, generic or everyday places can be considered, contrary to traditional laboratories that have to be held in dedicated or specific premises.
