“…In the works mentioned above, original applications were used. However, in our previous work [11][12][13], we used commercial applications. In this case, the measurement accuracy of the applications also needs to be continuously checked: The results of the accuracy tests of our previous work may no longer be applicable to verify currently available tools even for educational purposes in a quantitative sense.…”

“…Considering the above situations, we proposed an introductory teaching program of urban acoustic environments using a mobile device (hereafter, this term is used for both smartphones and tablets) with applications for acoustic measurements [11][12][13]. In these studies, the outcome was supposed to be a map with the following characteristics: comments on the acoustic environment at some specific points, in a certain area in a city, where a characteristic sound was heard, and its physical measurement data (e.g., sound spectra and A-weighted sound pressure levels) measured by mobile device (iOS) applications [11,12]. This is a kind of simple sound map describing urban acoustic environments.…”

“…This is a kind of simple sound map describing urban acoustic environments. By adding the measured value of, for example, SPL at various points, typical physical phenomena such as attenuation due to the shielding effect by other buildings can be understood by looking at the SPL data recorded on the map [11]. Also, sound spectrum data give clearer characteristics of the sound heard.…”

In this paper, we revisit the acoustics education program using mobile devices to better understand urban environments. We begin with a summary of our past projects to demonstrate a model case of the concept. In these projects, the output was mainly supposed to be a noise map with measured sound pressure levels (SPLs) and sound spectra. This methodology can obviously be applied to larger-scale urban studies. Including measured sound spectra can be another advantage. Next, current problems in measurement accuracy due to recent device developments are explained and the required examinations are stated. Finally, the accuracy of the current versions of the applications as well as recently available devices are discussed. The results of this study provide information regarding the measurement accuracy of mobile devices, and some suggestions for their practical use are given, which are also useful for additional studies pertaining to the urban acoustic environment.

“…Nowadays, smartphones are quite popular among students. Therefore, using such devices, it would be possible to provide them an opportunity to make an exercise to measure physical values with their spontaneous interest [2][3][4][5][6]. In this report, as a test case, we conducted an introductory teaching program for understanding sound environment by using a smartphone, and discussed its potential possibility and development.…”

In an introductory course for environmental/architectural acoustics in universities, it is often used the teaching method based on soundscape, in which students are asked to make a sound map with listening their surrounding acoustic environment. However, if objective measurement of sound pressure level or frequency spectrum can be introduced in such a course, it will interest students in environmental acoustics, and enable them to discuss the acoustic environment more profoundly. Measurement apparatuses are usually expensive and difficult to be used in such a course. Therefore, we consider to use a smartphone: using a smartphone with acoustic measurement applications, it can be possible to introduce an objective measurement in such an introductory course for beginners. In this study, first some applications for acoustic measurement are examined to confirm their accuracy as well as the effect of a simple handmade windscreen. Secondly, using suitable applications, as a possible work in the course, sound maps with measurement results by a smartphone are made and their examples are shown. Finally, some issues to introduce this method in actual courses are discussed.

Abstract:Automatic control systems is the specialized fundamental course of automation major. The teaching effect of this course will influence the learning of the post-requisites. It's important to improve the teaching quality of this course. This paper analyzed the problems of existing teaching methods. According to these problems, teaching reform methods were proposed to engage and motivate students' initiative, strengthen the students' capability of analyzing and solving problems.
