Psychoacoustics Lab
Machine-translated · View original
A lab that studies environmental noise and vehicle sounds based on how people hear them.
AboutAbout the lab
Exploring noise and sound design through how people hear.
Associate Professor Katsuya Yamauchi's lab studies environmental noise and sound design from the perspective of the psychology and sensory evaluation of people listening to sounds.
Recently, the lab has been particularly interested in what future vehicle sounds should be like, and focuses on the sounds of next-generation vehicles such as hybrid and electric vehicles.
It also works on predicting road traffic noise and designing signal sounds.
Key terms
- Subjective Evaluation
- A method of evaluating sounds in which the people who listen to them rate how they perceive them, for example as loud or pleasant.
- Sound Power Level
- A quantity expressing the amount of sound emitted by a source itself. It is used in road traffic noise prediction formulas.
- Vehicle Approach Warning Sound
- A sound that a vehicle emits to let people nearby know that it is approaching.
ResearchResearch themes
This lab investigates both environmental noise and vehicle sounds, using how people perceive sound as a starting point. Its main themes are predicting road traffic noise, designing sounds for next-generation vehicles, and designing vehicle approach warning sounds.
*Illustrative imagePredicting Road Traffic Noise
The lab studies methods for predicting road traffic noise. It also examines the uncertainty that comes with such predictions.
*Illustrative imageSound Design for Next-Generation Vehicles
The lab studies the sounds of vehicles such as hybrid and electric vehicles from a sound design perspective. It investigates how people perceive these sounds through subjective evaluation, and considers what future vehicle sounds should be like.
*Illustrative imageSpread of Next-Generation Vehicles and Its Effect on Noise
The lab investigates how road traffic noise will change as electric and hybrid vehicles become widespread. It evaluates the effects using prediction formulas and sound power levels.
*Illustrative imageDesign of Vehicle Approach Warning Sounds
The lab studies the design of approach warning sounds that let people nearby know that vehicles such as hybrid vehicles are approaching. It investigates how listeners perceive these sounds through subjective evaluation.
