Experimental validation of acoustic intensity bandwidth extension by phase unwrapping.
The phase and amplitude gradient estimator (PAGE) method for active acoustic intensity uses pairwise microphone transfer functions to obtain the phase gradient, which improves the calculation bandwidth over the traditional weighted quadspectral method. Additionally, for broadband sources, the PAGE theory indicates that the transfer function phase can be unwrapped to further extend the usable fr...
متن کاملMeasurement of complex acoustic intensity in an acoustic waveguide.
Acoustic intensity is normally treated as a real quantity, but in recent years, many articles have appeared in which intensity is treated as a complex quantity where the real (active) part is related to local mean energy flow and the imaginary (reactive) part to local oscillatory transport of energy. This offers the potential to recover additional information about a sound field and then to rel...
متن کاملIntensity Characteristics of the Noctuid Acoustic Receptor
Spiking activity of the more sensitive acoustic receptor is described as a function of stimulus intensity. The form of the intensity characteristic depends strongly on stimulus duration. For very brief stimuli, the integral of stimulus power over stimulus duration determines the effectiveness. No response saturation is observed. With longer stimuli (50 msec), a steady firing rate is elicited. T...
متن کاملDroplet behaviour under high intensity acoustic vibration
The reduction in scale of fluidic based chemical and biological processes offers significant analytical and sensitivity improvements as well as reduced reagent usage, increased automation and reduced manufacture costs. Droplets deposited on a planar surface offer a convenient way of investigating very small sample sizes. We investigate the effect of vibration of droplets in the direction normal...
متن کاملDesigning artificial enzymes by intuition and computation.
The rational design of artificial enzymes, either by applying physico-chemical intuition of protein structure and function or with the aid of computational methods, is a promising area of research with the potential to tremendously impact medicine, industrial chemistry and energy production. Designed proteins also provide a powerful platform for dissecting enzyme mechanisms of natural systems. ...
