High frequency gravitational wave generator

A high frequency gravitational wave generator including a gas filled shell with an outer shell surface, microwave emitters, sound generators, and acoustic vibration resonant gas-filled cavities. The outer shell surface is electrically charged and vibrated by the microwave emitters to generate a first electromagnetic field. The acoustic vibration resonant gas-filled …

The frequency and amplitude of ultrasonic vibration must be passed with a suitable arrangement to the object so that required changes can be made in the object. 6 For a long time, the effect of ultrasonic vibrations has been studied for different manufacturing processes and observations have been reported. 7 Ultrasonic vibration being a high …

Plant vibrations at all scales: a review

The frequency is also a measure of the margin to buckling (Timoshenko and Gere, 2009). Impacting leaves by an acoustic field is also efficient to evidence the changes in local properties due to water stress, (Sano et al., 2015), and fruits can be tested by high-frequency probes (Hou et al., 2018). In that case, it is the property of the bulk of ...

Floral vibrations by buzz-pollinating bees achieve higher frequency

Vibrations play an important role in insect behaviour. In bees, vibrations are used in a variety of contexts including communication, as a warning signal to deter predators and during pollen foraging. However, little is known about how the biomechanical properties of bee vibrations vary across multiple behaviours within a species. In this study, we compared the …

A review of vibration analysis and its applications

Only high frequency signals remain after the vibration signal is filtered. Shock pulse method measures the shock pulse signal upon the impact of a roller with a race defect. The transducer reacts with a large amplitude oscillation to the weak shock pulses meaning only its natural frequency at 32 kHz is recorded while lower frequencies are ...

The scientifically proven effects of vibration …

Therapeutic applications of vibration have been shown to significantly increase blood flow (3-5) . In one trial vibrations at both 30 and 50 Hz were shown to substantially increase peripheral blood flow, with 50 Hz giving …

Noise and vibration management: environmental permits

Vibration impact assessments should follow the methodology of 'BS 6472: Guide to evaluation of human exposure to vibration in buildings'. You should get advice from a dedicated vibration ...

Frontiers | Beyond Chemical Triggers: Evidence for Sound …

Humans can differentiate and recognize sounds ranging from 20 to 20,000 Hz. If the sound vibration used to treat plants causes damage to animals, humans, or microbes after long-term exposure, a detailed examination and evaluation of the effects of various exposure times and high-frequency (e.g., above 20,000 Hz) will be required.
