Structural Acoustics & Vibration Technical Committee

The Structural Acoustics & Vibration Technical Committee includes the study of motions and interactions of mechanical systems with their environments and the methods of their measurement, analysis, and control. Principal topics considered are: Responses of mechanical systems to dynamic excitations, Instrumentation and calibration techniques for measurement of shock and vibration, Resonances of structures, Damping and internal friction,  Isolation of mechanical systems from shock and vibration, Mechanical impedance (mobility), Modal analysis, Simulation of environmental factors, Development and application of analytical techniques and Active control of structural acoustics and vibration. See our recent article in Acoustics Today.

Scope

The Structural Acoustics & Vibration Technical Committee includes the study of motions and interactions of mechanical systems with their environments and the methods of their measurement, analysis, and control. A recent article in Acoustics Today reviewed the scope of this committee. Principal topics considered are:

  • Responses of mechanical systems to dynamic excitations,
  • Instrumentation, including calibration techniques, for measurement and analysis of shock and vibration,
  • Resonances of structures,
  • Damping and internal friction,
  • Isolation of mechanical systems from shock and vibration,
  • Mechanical impedance (mobility),
  • Modal analysis,
  • Simulation of environmental factors,
  • Development and application of analytical techniques,
  • Active control of structural acoustics and vibration.

Applications

  • Aircraft or launch vehicles moving through the atmosphere
  • Underwater vehicles or surface ships moving through water
  • Vibration from transit systems propagating through the ground and into buildings (and radiated as sound inside those buildings)
  • Vibration of buildings caused by sources on or within (mechanical, transportation, or human generated)
  • Musical instruments (Excitation, response and sound radiated)
  • Methods for determining soil composition and detecting subsurface resources
  • Consumer products (Noise-Vibration-Harshness)
  • Transducers that measure or generate sound and vibration
  • Biomedical devices
  • Hearing aide design
  • Vibration generated and sound radiated by mechanical equipment
  • Health monitoring and nondestructive evaluation of machines and structures
  • Response of pipes to fluctuations within the entrained fluid
  • Metamaterials
