A Hands-on

Sound Academy is a lecture to learn sound from A to Z by experience with using your voice.

It is for anyone above 10 years old who have no knowledge about sound at all, and there is nothing difficult to understand - we use videos, audios and your voice as much as possible to help you learn.

What People Say


Translated It was so much fun and nice to have such an unique experience. A variety of videos and practices help make it fascinating.

Translated Realised that I didn't care about sound although it's always there in my daily life. It was fun!

— 7 Jul 2012 Nagoya, Japan

Translated I studied something about soundwave in the science class, but this is the first experience to study it further, so everything was very interesting to me.

— 24 Aug 2012 Kumamoto, Japan

Translated Lots of hands-on experiences and examples from the daily life helped me understand how sound works from various aspects.

— 10 Aug 2012 Nagoya, Japan

Translated So interesting to know deeper about sound which is too common and familiar to turn my attention to. "visualising" the sound was also nice. Now I'm happy about being able to tell what is happening around me.

— 10 Aug 2012 Nagoya, Japan

Translated As a radio presenter, I am here since I wanted to have a good knowledge of sound. Profound - is a word in my mind now. I am motivated to make my radio program entertaining from a perspective of sound.

— 10 Aug 2012 Nagoya, Japan

Translated Today I learned the marvels of human body through knowing the nature of sound. It's interesting to imagine that our eyes and ears could have been just one each if our bodies were simpler or there were less danger for human beings, and on the other hand, some other system could have been in our bodies if there were more danger.
