Acoustics and Noise Control

Purdue is a renowned center for research and education in Acoustics and Noise Control, focusing on both computational modeling and real-world experimentation.  With an array of data-gathering tools, and numerous facilities to conduct experiments, Purdue faculty and students are evaluating the acoustic properties of:

  • Cars and trucks
  • Airplanes
  • Buildings
  • Homes & offices
  • Industrial machines
  • Computer equipment
  • Appliances
  • Medical equipment

Researchers also focus on the human aspects of noise control.  Experiments are determining how people react to the acoustic properties of their homes, workplaces, and vehicles.  With this information, new noise control technologies can transform our everyday environment into a healthier and more productive place.

Facilities available:

Acoustic Audiometric
  • Anechoic rooms
  • Reverberation rooms
  • Tire-pavement testing up to 50 km/hr
  • Two-wheel dynamometer with 67-inch rollers
  • Anechoic wind tunnel up to 120 mph
  • Audiometric testing room
  • 64-microphone acoustical holography array
  • Acoustical materials laboratory
