Expected prior knowledge
Although knowledge on sound design and perception is convenient, every year students successfully participate that do not know how to design sounds and lack knowledge on auditory perception. The course is set up such that everybody can participate.
Course Contents
Have you ever wondered...
...how well our hearing system can perceive the feedback sounds of an ATM in a noisy environment?
...what acoustical properties make an alarm sound (in-)appropriate for an emergency situation?
…how a Lexus parking signal should be designed?
...how you design these sounds?

Who does not get irritated by feedback or alarm sounds that do not give the experience of quality or sound at improper moments? This happens because many designers and engineers do not have the knowledge on auditory perception and do not know how to design sounds. In addition, sound design is interaction design. If one does not make a good analysis of how the interaction of a user with a product or environment is, one cannot design sounds that fit this interaction.

In the Interactive Audio Design course you will learn fundamental theories on auditory perception and music psychology, and how to apply this knowledge to recording & playback techniques, sound measurements, and sound synthesis approaches. You will learn to express a sound vision and to conceptually analyze it, which will help you to create and evaluate your sound design. You will learn how to design a sound for an abstract concept or brand values (like, e.g., sustainability), how you can attribute meaning to a sound (this is parking signal for a car), how you can make sounds that convey a certain sense of urgency.

In this quarter you will redesign an intentional product sound. These sounds are deliberately added to the product by means of speakers or piezo elements. The function of these sounds is to alarm users, or to provide them with feedback. Therefore, interaction design plays a major role in the sound design process. Cases of previous years included the OV chip-card sounds, and interior sounds for future Toyota and Lexus cars, sounds for control rooms of the European Space Agency. In this year course we will work to design sounds for the future Dutch police car and work on interactive Soundscapes for the Maxima Children's hospital.
Study Goals
• To learn basic principles of sound recording & sound measurement
• To learn basic principles of sound analysis, using tools such as Praat
• To learn basics sound synthesis techniques, using tools such as vocal sketching, Praat, MaxMSP, Audacity, and Sound Studio.
• To be able to translate experiential aspects (perceptual and emotional) into alarm and feedback sounds.
• To learn how to present your sound design ideas.
• To learn how to use an interaction vision to design your sounds
Education method
The project will be carried out in groups of two or three students for practical reasons (e.g., recording, disassembly, brainstorming). To support the projects, there will be frontal lectures on sound perception, analysis, and synthesis. In addition, there will be practical exercises that you will learn to design sounds. Although prior knowledge on the design of sounds is useful, also students that do not know anything on sound accomplish to acquire the skill to create sounds. Sound recording takes place in the Audiolab, which also facilitates analyzing sounds and conducting perceptual tests. Each project ends with a plenary presentation.
