Technical Committee on Structural Acoustics and Vibration (original) (raw)

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
