Online Activities for Learning and Listening

Web-based, cross platform games designed to illustrate pscyhoacoustic concepts to K-12 students and collect human evaluation data. These games introduce players to problems in speaker identification and musical timbre recognition through interactive interfaces that encourage learning through experimentation.

Hide & Speak - BETA

This game simulates the well-known acoustic situation called the "cocktail party problem" by providing an interface that enables modification of acoustic space, sound source and listener parameters. There are two components to this game that allow for both the experimentation of audio created from different room configurations in the Room Creation component and listening evaluations of the created rooms in the Room Listener component.

ToneBender is an online, collaborative game that illustrates concept of musical timbre through interactive gaming interfaces. In addition, the game serves as a tool for engineering education and the collection of human evaluation data. The ToneBender contains two interfaces, Tone Bender and Tone Listener, which allow for the creation and identification of musical sounds, respectively. The purpose of Tone Bender is to have players modify the timbre of musical instrument sounds and to collect those sounds in a database. Players can then listen to the sounds others have created in the Tone Listener interface in order to determine if they can identify the original instrument. Read on to learn about the different game interfaces.

Online Activities for Music Information and Acoustics Education and Psychoacoustic Data Collection - ISMIR 2008

We have created prototype interactive activities illustrating aspects of two different sound and acoustics concepts: musical instrument timbre and the cocktail party problem (sound source isolation within mixtures). These activities provide a method of collecting perceptual data related to these problems with a range of parameter variation that is difficult to achieve for large subject populations using traditional psychoacoustic evaluation.

Online Acoustic Simulations for Education and Listener Evaluations - Drexel University Research Day 2008

Online collaborative activities provide a powerful platform for the collection of psychoacoustic data on the perception of audio and music from a very large numbers of subjects. Furthermore, these activities can be designed to simultaneously educate users about aspects of music information and acoustics, particularly for younger students in grades K-12.
