Acoustics Group

The acoustics research program at BYU is cross-disciplinary, involving the treatment of both fundamental and applied problems in acoustics and vibration using analytical, numerical, and experimental means. It focuses primarily on acoustic signal processing, active and passive noise and vibration control, aeroacoustics, architectural acoustics, audio acoustics, nonlinear acoustics, outdoor sound propagation, and sound-structure interactions. Many resources are readily available for the effective simulation, measurement, and control of physical systems. In addition to strong computational facilities, the program has acoustical laboratories with extensive state-of-the-art measurement equipment, two anechoic chambers, two reverberation chambers, and a variable acoustics chamber that can be used for experimental studies.

Research Projects

  • Research in shock waves and high-amplitude acoustics

    A lot of my research involves high-amplitude noise, like jets, rockets, explosions, and sonic booms. Other possibilities exist - email me to set up an appointment.  Numerous publication opportunities are likely.

    I'm *always* looking for new students in this area. Right now I'm looking for 2-3 students.




    Suggested Preparation:

     We'll teach you!

    Suitable for
    • Undergraduate students
    • Graduate students
    • REU students
  • Environmental Noise Monitoring and Modeling

    I am working with Dr. Transtrum and graduate students on a project to use machine learning and geospatial features (nighttime radiance, precipitation, forests, etc.) to predict ambient soundscapes throughout the U.S., and eventually, globally.  We have a need for 1-2 outdoor-oriented students interested in conducting making sound measurements in different urban and rural environments, formatting the data outputs, analyzing them, and helping to feed them into the machine learning models created by the graduate students. 

    Suggested Preparation:

    Experience with Excel useful.  Likely requires some hiking from time to time.

    Programming experience in Matlab or Python a plus.

    Interest in learning about acoustics and instrumentation.

    Suitable for
    • Undergraduate students
    • Graduate students
    • REU students
  • Machine learning and crowd noise

    This project, with Dr. Transtrum, combines machine learning with crowd noise at sporting events. We want to detect cheering, booing, or even the beginning of crowd violence. This could involve taking data, analyzing them for features that relate to crowd engagement or sentiment, or developing new machine learning models.

    We are currently looking for two students, one on the acoustics side for measurement and analysis, and one on the machine learning side.

    Suitable for
    • Undergraduate students
    • Graduate students
    • REU students
  • Passive acoustical monitoring of wildlife

    Passive acoustic monitoring of wildlife has many purposes, but include studying population health, size, and dynamics.  We're currently doing research at the Bear River Migratory Bird Refuge, looking at how water and other environmental factors impact bird choruses.  We may also be starting to do rocket noise-related research - as launches can affect noise sensitive species - in California.

    I'm looking for a student interested in measurements and analysis.

    Suggested Preparation:

    We'll teach you!

    Suitable for
    • Undergraduate students
    • Graduate students
    • REU students
  • Weapons noise and hearing loss

    I'm working with the Office of Naval Research and Air Force Research Laboratory to develop better physics-based mathematical models for noise exposure at indoor and outdoor shooting ranges.  

    Why?  Because 12% of marines exit basic training with significant hearing loss. This research directly protects soldiers...as they work to protect us!

    Looking for a student on this project.

    Suitable for
  • Rocket noise

    Dr. Grant Hart and I are studying the noise from rockets and launch vehicles.  There is a LOT of interest in rockets right now as many companies around the world are developing new launch vehicle technologies. This involves potentially exciting measurements and a lot of collaborative data analysis opportunities.

    We are looking for a couple students.


    Suitable for
  • Military jet noise

    We study the noise radiation from turbulent jet engine exhausts.  We've studied the F-22, the F-35, and the T-7A using lots of different methods for the Air Force and the Navy.

    I'm looking for 1-2 students to join this group of ~5 students.

  • Computational Underwater Acoustics

    Large arrays of hydrophones in the ocean can be used to locate acoustic sources.  The reliability of these localization algorithms depends on the degree to which the ocean environment is correctly parameterized in the models.  

    The computational models for sound propagation in the ocean depend on the ocean environment.  My work involves using sound from the ocean to estimate the ocean environment.  One part of the research works on determining the sensitivity of different seafloor parameters and determining which seafloors make a big enough difference on the sound propagation to be detected.  The other part explores optimizations and how machine learning can be used to identify seafloor properties from different types of sounds.

    I am currently looking for two students to join my computational underwater acoustics research.  Research in this area will provide a strong foundation in computational skills, numerical modeling, and deep learning, all of which will prepare students for additional opportunities in industry, national laboratories, and graduate school.

    Suggested Preparation:

    Desire to learn about acoustics and dive into numerical modeling and/or machine learning.

    Computer coding experience is helpful.  This project uses Python.


    Suitable for
    • Undergraduate students
    • Graduate students
    • REU students
  • Underwater Acoustical Measurements

    Our underwater acoustics lab (U117) has a fully automated system for making acoustic measurements in our water tank (12 ft long by 4 ft wide).  Currently measurements are being made test which numerical models accurately predict sound propagation in the tank at ultrasonic frequencies.  The big upcoming goal is to be able to test machine learning algorithms for source localization and environmental variability using ultrasonic tank measurements.

    I am currently looking for two students to join my underwater acoustical measurement group.  The opportunity to do experiments in a water tank at ultrasonic frequencies offers a solid foundation for students interested in studying ultrasound or other medical physics fields in graduate school.  In addition, the experience with measurement protocols, programming the robotic arms, and analyzing the data with signal processing techniques provide a good foundation for many technical jobs.
