Vol.1-3 asking audio / acoustic experts
Kyushu University Graduate School of Arts and Engineering Dr. Kazuhiko Kawahara
"What is the acoustic design that Kyushu University of Engineering and Kyushu University Art Engineering?"



This is a plan to invite people who are active in various fields related to sound and talk about various themes about "sound" by our chief scientist. The first time, we talked to Dr. Kazuhiko Kawahara of the Kyushu University Graduate School of Arts and Engineering, which FINAL is currently conducting joint research. I wrote the text as it was, so I think there is something difficult to read, but I think that you can feel the words of the speaker from the text. I will share the story that I heard for about 4 hours into the main items. Part 3 is "What is the acoustic design that Kyushu University of the Arts, Kyushu University Art Engineering has?"

What are the acoustic designs that Kyushu University of the Arts and University of Art and University of Arts?

Hamasaki: A university that was entered that way. Kyushu University of Art and Design. So, an instructor of Kyushu Art Engineering University. Was it the Kyushu University Faculty of Arts and Engineering now?

Kawahara: It's Kyushu University Faculty of Art and Engineering.

Hamazaki: Kyushu University and Kyushu University of the Arts are integrated, and the Kyushu University Faculty of Art and Engineering is now on the Ohashi campus in the southern ward. Here, the academic design, or the subjects of the subjects, and the graduates of a lot of graduates, what was the role of acoustic design, or the role that the department played? Or, I'd like to ask you what it will be in the future. The teacher is just at the top of the education. How is it?

Kawahara: Even in Japan, there are not many faculties or courses that are sounding so sound and the sound. In many universities, for example, architecture, information, electronics, and some of the music in the art, psychology, the Faculty of Arts, and the music in the art. Although such educational research is being conducted. It's sound, especially today's topic, but it's not just about audio engineering, audio, but at that time, not only the audio of the image I entered, but also music or music. Well, there are music, music, music, music analysis, hearing and sound -related, and noise control, and the evaluation of noise. This is the only college. Probably, there are similarities in the world, but that kind of place does not have music, musicians, or expressionists, and focus on hearing, and focus on architectural sound. I'm like that. Also, there are universities and research institutes that focus on signal processing, but there are educational research on a wide range of sounds, including such music and linguistics. I think it's only Kyushu University's Faculty of Arts and Engineering. At that time, I heard when I was a student, and in the category of acoustics and acoustic society, there are areas that are not. It is ultrasound and underwater sound. The reason for the art engineering is a university that thinks about technology mainly by humans, so in that sense, ultrasonic waves cannot be heard by humans. In the underwater sound, people say that underwater sounds do not live in the water at the University of Technology because people do not live underwater. The acoustic design department, the acoustic design course, a reorganization and a student of the acoustic design course is in the first grader of the second year, but I think that we have developed human resources who can understand the various aspects and value of sound. 。 This is not the one who knows electronic engineering, but also the music and the expression of the artist. Then, you can see what is the interior sound of the hall at that time. If you know the equipment used in the hall. If you understand all of those people. And it's a related field. For example, electrical and electronic engineering or social sciences in a broad sense. In conjunction with education such as economics or cultural anthropology, it is a way to provide a solution by linking with an expert in other fields to provide a solution. I think. So, for more than 50 years since the founding of Kyushu University of Art and Design, I went around as the first -year students were retired. Under such circumstances, I think that about 40 people a year are worth providing such unique education to a Japanese society, developing, research, and education. Masu. I think that it was the philosophy of the establishment of the Faculty of Arts and Engineering, not only knowing the sound but also the people in the related fields that could understand the words of people in the related field. Masu.

Hamasaki: It's been about 50 years since the founding of Kyushu University of the Arts, and of course, the position of sounds, sounds in industries, or audio has changed as the industry has changed. That's right. For example, at the time of the university, the circuit called analog was commonplace, but it moved to digital as mentioned earlier, resulting in a digital signal processing. Then, for example, the equipment will change. If you have a personal computer now, you can really do what your teacher really tried to go to college. Even though one speaker has not changed in principle, of course, the position in society is changing. Is there a social environment for sound and how the society has changed to the sound, and the situation of university education has changed little by little?

Kawahara: That's right. For example, audio is becoming smaller in Japan, especially in Japan. In terms of communication, I think that there are many people who are developing or developing services related to mobile phones, smartphones, or smartphones. 。 At the same time, the sound quality is a new place. Machinery, such as the sound of a car, such as the sound of a car door, the exhaust sound, the quality of such a thing, the quality of communication, and such a way of thinking about such things are also being conducted. Also, in understanding that, the basic sound theory and physical sound theory are basically the basics, while changing the teaching style little by little, while changing the teaching style little by little. With the image of the image and acoustic circuit, education is being conducted with a viewpoint of how to make a digital circuit. I think it is changing little by little now.

Hamasaki: Basic acoustic engineering, acoustic theory, chamber sound, and hearing, of course, I think that various studies have been done every year and have been understood. What are the new fields recently, what are the learning of the sound -related music that has appeared in the field of education? Even if you say it recently, it may be about 10 years.

Kawahara: Among the hearts of hearing, I think that it is great that teachers who are well studying physiology have entered. Also, the difference is a little different from when we were a student, and there are still teachers, composers, or musicians. So, I think it would be more powerful to be able to teach directly and performances. I think that collaboration between teachers in the field and teachers close to us like us is a field that is expected in the future.

Hamasaki: A study that focuses on technology. Or maybe the music you've said, or recently media art, or that kind of creation, I think it's because it's called art engineering, but it's always moving on both wheels. Kane. While changing, is it just now, while keeping the art and engineering axis?

Kawahara: That's right. In the field of engineering, and in the field of media art, there are OB teachers, and they are stimulating each other. At one point, in the current exchange with Mr. Hamazaki, a teacher told me that art engineering is not an art and engineering, but a one -phrase in art engineering. 。 At that time, I didn't understand. Certainly, at least the concept of art and engineering is in conflict, at least students do not learn with such consciousness. By receiving lectures from art teachers and engineering teachers, art engineering is accumulated in the students themselves or accumulating. I have had the opportunity to think about the 50th anniversary of my own art engineering. I think that art engineering is a study to make people happy. That's why I am in the sound design, so I think it's happy to use the sound and it doesn't have to be an outright happy, but to be able to stay naturally, more valuable sound space. I thought that providing nations would be my goal of acoustic -designed art engineering in acoustic design. I don't say much in front of the students, so if you talk like this, you will be annoyed. When you have any opportunity, you'll be asking what kind of way is the most happy, for those who receive the service, or for those who listen to the sound. How about?

Hamasaki: So is me too. In myself, I sometimes do something like an art, and maybe I can't do it, and maybe I can't do it by ward. For example, making works of electronic music. But I use engineering. Sometimes you're doing something very technical. Just do the formula for signal processing. But isn't there a sound to pass there? Of course, I'm glad if I can know and solve it. But after the solution is solved, the sound that actually passes, the sound that has been created becomes a very good sound, and it is probably the same for ordinary people to hear it. I think it is. There is. So where are you? I don't think it's a close -up, but it's both. Furthermore, not only the sound, but also the video, of course, there is a video, and if you do not know the video, you can not do the sound work, so in that sense I do not understand my specialty. If you have something you want to do in front of you, it's like doing it for the time being.

Kawahara: That's right. I think Dr. Inoue Inoue said that kind of thing. I was my homeroom teacher. I'm an engineer, so I don't know about art engineering. You guys are in the art engineering education. You mentioned what you guys are doing in art engineering. So, after all, I don't think you'll know the whole thing about art engineering unless you leave the Faculty of Arts and Engineering. So, in that sense, I think Makita -sensei, who designed the acoustic design department at the time, was a great person. You divided into four fields and have each professor and teachers? It's very difficult to design such a new department in college now. I think it's hard to try to reorganize while there are actually realistic people. Anyway, the fact that Mr. Makita designed the acoustic design department was very forced. I guess the allocation in that field was very appropriate. Technical humanization, including the fact that underwater and ultrasonic waves were removed from the acoustic society? Did you make good use of the purpose of art engineering? I am grateful that the acoustic design is a subject and course where students from all over the country are gathering at the moment. People with high motivation gather. It is very grateful that there are students who are thinking of what they want to do purely, do something, or do something.
