The lab researches acoustic signal processing to control the three-dimensional feel of sound with loudspeakers and microphones.
AboutAbout the lab
Toward technology that controls 3D sound freely
The Haneda Lab studies acoustic signal processing, aiming to build highly immersive 3D audio technology and control technology that can shape sound fields freely.
Based on array signal processing with multiple loudspeakers and microphones arranged in arrays, the lab studies interactive audio, in which sound images floating in the air are manipulated directly by hand.
Day-to-day research centers on algorithm development using computer simulation. Finally, the lab builds a system and evaluates its performance through sound field measurements and subjective evaluation experiments.
It is also a lab where students work with hardware, such as making their own loudspeaker and microphone holders with 3D printers.
Key terms
- Loudspeaker Array
- A set of multiple loudspeakers arranged together. This lab uses arrays arranged in a line or on a sphere
- Virtual Sound Source
- A sound source created in the air at a position with no loudspeaker, serving as the apparent origin of the sound
- Sound Field
- The state of the space through which sound travels from the source to the ear

ResearchResearch themes
The Haneda Lab conducts research based on array signal processing with multiple loudspeakers and microphones, aiming to build highly immersive 3D audio technology. Recently, it has focused on realizing interactive audio technology in which sound images floating in the air are manipulated directly by hand.
*Illustrative imageManipulating Sound Images Floating in the Air
Using a linear loudspeaker array of 32 loudspeakers and a spherical loudspeaker array with loudspeakers placed on a sphere, the lab creates virtual sound sources at positions in the air where there is no loudspeaker. It manipulates the sound sources according to movements captured by motion capture and investigates the feel of operation and the sense of physical presence.
*Illustrative imageDirection and Strength of Speech Radiation
The lab investigates speech radiation characteristics, that is, in which direction and how strongly a person speaks, and also works on simulating them. It visualizes the sound pressure radiated to the surroundings when a person speaks.
*Illustrative imageSound Field Measurement and Noise Control
In an ordinary room, sound repeatedly reflects and diffracts, and its characteristics change greatly even over a distance of 5 cm. The lab therefore measures sound fields and radiation characteristics and, through interpolation and extrapolation of sound waves, studies applications to sound field reproduction and active noise control.
MembersFaculty
The members of the Haneda Lab consist of faculty, doctoral, master's, and undergraduate students, research students, and visiting researchers.As of 2026
