  • Acoustic Emission
    Acoustic emission is specific flaws or features within a mechanical system that provide specific acoustic or vibrational responses. If a break, deformation, or other failure occurs in a piece of equipment, sensitive acoustic emission sensors can detect the high frequency burst given off during
  • Acoustic Emission / Noise Detection Instruments
    acoustic or vibrational responses. If a break, deformation, or other failure occurs in a piece of equipment, sensitive acoustic emission sensors can detect the high frequency burst given off during the event. Monitoring acoustic emissions can also access the location and severity. This NDT technique
  • Applying Acoustic Vibration Monitoring to Predictive Maintenance

  • OH Emission Spectra of Hybrid Rocket Motors Using
    to achieve in a rocket motor exhaust plume. Exhaust plumes radiate. energy to their surroundings. They blast off material into and entrap molecules from their environment. Some of. their energy is dissipated in the acoustic region. Also, there is only a short time available for equilibrations
  • Clever combustor yields super-low emissions
    emissions low, the injection path and chamber geometry are complex. The combustor burns fuel in low-temperature reactions throughout the combustor. This avoids acoustic instabilities of current low-emissions combustors. It does this by eliminating all high-temperature pockets of combustion through better
  • Particle Impact Noise Detection (PIND)
    Acoustic testing services include the evaluation of the condition of materials, products, and equipment; acoustic analysis of signals from analog or digital recording media or products; and investigation of the effects of noise on people, components, materials, or products. Acoustic emission
  • Medical Device Link .
    When an earthquake causes small cracks in structures such as bridges or vessels, the cracks release inaudible sound waves. These waves, called acoustic emissions, can be monitored with special ultrasound sensors. Likewise, when a crack forms in bone, a wave similar to the type created
  • Alenia Spazio Optimizes Noise & Vibration Performance of Space Systems
    Alenia Spazio defined and developed an integrated test/simulation process, which allows meeting the tightest micro-gravity and vibro-acoustic requirements inside manned space vehicles. Once in space, on-board conditioning and electric power systems induce noise and vibration levels that potentially
