Audio processors as a learning tool for basic acoustics

Abstract

Basing on the audio processor Audacity, this paper presents the use of this kind of\ud programs as a so called “hear-and-see” learning tool for basic acoustics. Some activities\ud designed as laboratory experiments, which can be carried out also remotely in a sort of\ud home laboratory, have been already successfully implementedPreprin

Comparative study of three audio processors as environments for laboratory activities on wave physics and acoustics

“…Indeed, many of them have been already implemented within an elective course on acoustics in our engineering college, as described in Ref. 50. In the following, we describe them briefly:…”

“…See Ref. 50 for a more detailed description of this activity using Audacity. Figure 2 shows the display of such a sound sample in Adobe Audition, giving four musical notes (F 1 -F 4 ) from a trombone in octave distances.…”

“…See Ref. 50 for a more detailed description of this activity using Audacity. As an example for the possible results, Figure 3 shows the relative intensity level of the first 15 harmonics obtained by a given student (in his own representation).…”

“…6; see a complete description in Ref. 50). For grading the test loudness, students do not have to use any audio processor, but any other audio player (e.g., Microsoft Media Player) with no waveform display, that is, no clue to any loudness value.…”

Development of a virtual winder for computer‐aided education using Virtools

“…Courseware, based on computer technology and multimedia technology, has been becoming more and more widely adopted in almost all education levels. Pejuan and Novell 1 provide a “hear‐and‐see” learning tool for basic acoustics combining sound and image. In Gao and Wang 2 the process of constructing virtual hydraulic circuits by Flash is demonstrated in detail.…”
