Facilities and Labs

Sound Perception & Room Acoustics Laboratory

The Sound Perception & Room Acoustics Laboratory (SPRAL) is a research laboratory out of the Graduate Program in Acoustics at Penn State. The research team consists of both graduate and undergraduate members and focuses on topics related to room acoustic measurement techniques, virtual acoustics, spherical array processing, the subjective impression of room acoustics, neuroimaging, emotional processing of speech and music, and impact of noise upon learning and performance. Most SPRAL students are pursing a graduate degree in acoustics, but SPRAL also offers a wide range of different backgrounds, including electrical engineering, mechanical engineering, architectural engineering, signal processing, math, computer science, and physics.

Biomedical Acoustics Simon Lab

Started in 2017, the Biomedical Acoustics Simon Lab (BASiL) is a research laboratory in the Graduate Program in Acoustics, led by Julianna Simon, assistant professor of acoustics and biomedical engineering. The research activities in BASiL primarily focus on diagnostic and therapeutic applications of ultrasound with an emphasis on technologies that can benefit human spaceflight. Current graduate students have undergraduate degrees in acoustics, physics, and bioengineering.

Applied Research Laboratory

The Applied Research Laboratory (ARL) at Penn State is an integral part of the University and was established in 1945 at the request of the U.S. Navy. Originally focused on undersea weapons technology development, ARL now includes a broad research portfolio addressing the needs of various sponsors.

ARL supports national security, economic competitiveness, and quality of life through education, scientific discovery, technological demonstration, and successful transition to application.

As a Department of Defense (DoD) designated University Affiliated Research Center (UARC), ARL conducts essential research, development, and systems engineering in support of our nation’s priorities free from conflict of interest or competition with industry.

Applied Science Building

The Applied Science Building (ASB) is the house of the Graduate Program in Acoustics. It is located on the west side of Penn State’s University Park campus in State College, Pennsylvania.

The ASB auditorium has a large seating capacity, used for many conferences and seminars. It is equipped with a video projection system capable of displaying VHS, DVD and computer workstation graphics and has an internet connection. The setup is configured such that the classroom audio and video equipment can be relocated here.

This is the study lounge for acoustics graduate students. Lockers are provided for students and once a student begins work on a research project, a desk is usually assigned, typically within the specific research group.

A small lounge within the student area allows for some relaxation time between classes and work. This is the area where students usually take their lunch. It is also the location of the Acoustics Programs’s main collection of the Journal of the Acoustical Society of America (JASA).
