“…For example, we can consider simple practices, such as the study of stationary waves on a guitar string, to more complex situations, such as stationary waves in surfaces, resonating cavities, echolocalization, Doppler effect in moving sound emitters/receivers, etc. There is quite a lot of literature in using smartphones for teaching and in describing this kind of wave propagation practices, see for example [3][4][5]. In this paper, the novelty is to focus on designing practices where sound is used as a messenger, useful to better understand the physics involved.…”

The study of oscillations, waves, and sound is included in most first-year courses on Physics, however, analyzing audio recordings to understand and test physics experiments in laboratory practices is not a common practice, compared for example with the use of visual techniques. In this paper, we fill in this gap showing the usefulness of the application of sound recording and its analysis in Physics Laboratory practices of first-year Engineering University studies. Sound recording is very simple and implemented in commonly available technology tools, such as smartphones. The analysis can be done with ease in free open-source applications, such as Audacity. This means that this experimental procedure can be easily implemented and extensively used, even in distance learning, which is particularly convenient in a pandemic context. In fact, we illustrate in this work how this approach let us to successfully transform two in-person lab practices into sessions that can be run remotely: the study of free fall and measurement of the coefficient of restitution of a ball bouncing when released from a certain height, and the measurement of the speed of vehicles by analyzing the Doppler effect of the sound that the motor vehicles produce. With this, we conclude that this is a powerful technique that should be considered, alone or in combination with other techniques, for instance video analysis, when planning the lab practices of Physics courses.

“…De esta forma, los alumnos tienen una información mucho más rica (posición y/o aceleración en Congreso In-Red (2016) función del tiempo) para el estudio del movimiento armónico simple. Pueden calcular así el período, y compararlo con el que se obtiene de forma tradicional mediante la medida del tiempo de las oscilaciones (Sans et al 2016;Cuenca-Gotor et al 2015;. En la figura 1 se muestra una fotografía de la sesión de prácticas del muelle, y en la figura 2 se muestra con más detalle la colocación del teléfono móvil para la realización de la práctica.…”

“…Estas propuestas están en la misma línea que este trabajo, pero ninguna de ellas hace referencia a la implementación de estos experimentos en grupos de alumnos (Klein et al 2014;Kuhn y Vogt 2012;González y González Rebollo 2015;Huete et al 2015;Arribas Garde et al 2015;Kuhn y Vogt 2013;Sans et al 2013;CastroPalacio et al 2013;Tuset-Sanchis et al 2015;Castro-Palacio et al 2014). Solamente en algunos trabajos recientes realizados por nuestro grupo, aparecen las primeras referencias a la implementación de este tipo de experiencias con alumnos (Sans et al 2016;Cuenca-Gotor et al 2015;.…”
