“…In terms of basic knowledge, with the core feature that acoustic research needs to distinguish between frequency bands, the teaching content based on theories such as fluctuation acoustic method, geometric acoustic method, and statistical energy method is established for low frequency and middle and high frequency respectively [4][5]. Through these contents, students can master the basic theories necessary for acoustic simulation, so as to recognize the essential properties of acoustic problems, and have a deep understanding of complex problems under the support of basic theories.…”

Existing acoustic simulation courses are mostly heavy on software, light on theory and the practical teaching method is outdated, which leads to the students' single ability to solve complex problems, single problem solving idea, insufficient innovative application ability and other problems. In view of these problems, this course actively carries out teaching innovation, from the content system, the teaching form of two dimensions of innovation to realize the students to master solid acoustic simulation theory, skilled application of acoustic simulation software to deal with the problem, and the ability to use the software to carry out innovative design as the teaching objectives. In terms of content system, this course is centered on the core key point of acoustic simulation -applicable frequency band, respectively, for low-frequency, medium and high-frequency simulation, the establishment of fluctuating acoustics and geometric acoustics, statistical energy analysis of the combination of the content system, through the consolidation of theoretical knowledge, enables students to understand the principles of the corresponding software, and has the ability to expand the complexity of the problem. In the form of teaching, instead of focusing on the explanation of software operation in the classroom, the video of software explanation and real case explanation are carried out before, during and after the classroom, so as to realize the studentcentered practice in each section, thus improving the students' ability to solve problems with diversified ideas and innovative applications, and finally realizing the innovative goal of "strong foundation, heavy practice and innovation", The ultimate goal is to realize the innovative goal of "strengthening foundation, emphasizing practice and seeking innovation".

“…This soundcard oscilloscope could be used for many kinds of measurements. For example, the previous researchers have used it to measure the relationship between frequency and the amplitude of the voltage signal (Wild et al, 2010). In addition, the soundcard oscilloscope was free for public education purposes (Wild and Swan, 2011;Zeitnit, 2015).…”

In the present study, an experimental teaching material using a soundcard oscilloscope developed for science, technology, engineering, and mathematics (STEM) education considering the engineering viewpoint was applied to address student's misconceptions in the alternating current (AC) circuit topic in high school physics. Four experiments were conducted, and 13 conceptual understanding questions were used to explore the concept of the AC circuit among 192 secondary school students in Indonesia. This study concluded that the STEM system used in this study was considered to be useful to overcome the various misconceptions in high school physics. As a result of this study, it is recommended that more researchers should find, create, develop, and implement more teaching materials that support the understanding of students in AC circuits as well as the other parts of physics. Deeper investigations into the pre-conceptions of students would be another area of research that this study identified as an area of the focus needed in investigating cases of misconceptions.

“…There are examples for the use of sound card-based measurements for this type of measurement in the literature. For example, Wild and Swan [21] examined the spectra of musical instruments and steady waves in a one-end-opened pipe with a frequency sweep excitation technique.…”

“…As it has been known for many years [2][3][4], oscilloscopes can be replaced with sound cards with certain limitations, and many kinds of signal processing (including spectral analysis) can be implemented. The input of the RLC circuit can be driven by the output of a PC sound card, while the signals at the output of the circuit can be detected by the input of the sound card.…”

Real-time analysis of mechanical and electrical resonances with open-source sound card software

Abstract. We present an easily reproducible, open-source, sound card based experimental setup to support transfer function measurement. Our system is able to visualize signals of mechanical and electrical resonances and their spectra in real time. We give a brief description of the system, and show some examples of electrical and mechanical resonance experiments that are supported by the system. The theoretical background, experimental set-up, component selection and digital signal processing are all discussed, and more detailed information (building instructions, software download) is provided on a dedicated web page (http://www.noise.inf.u-szeged.hu/edudev/RealTimeAnalysisOfResonances/) The experimental set-up can support undergraduate and graduate education of students of physics, physics education and engineering by means of experimental demonstrations and laboratory exercises. The very low cost, high efficiency and transparent system provides a scalable experimental environment that can be easily built in several instances.
