The study of music provides many examples of the superposition of waves and the constructive and destructive interference that occurs. Very few examples of music being performed consist of a single source playing a single frequency for an extended period of time. A single frequency of sound for an extended period might be monotonous to the point of irritation, similar to the unwanted drone of an aircraft engine or a loud fan. Music is pleasant and exciting due to mixing the changing frequencies...

In order to examine gene expression in the pupal wing tissue of Bicyclus anynana, we present an optimized protocol for in situ hybridizations using riboprobes. We also provide guidelines for the further optimization of this protocol for use in pupal wings of other Lepidopteran species.

Source: Arianna Brown, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA Waves are disturbances that propagate through a material medium or empty space. Light waves can travel through a vacuum and some forms of matter, and are transverse in nature, which means that the oscillations are perpendicular to the direction of propagation. However, sound waves are pressure waves that travel through an elastic medium like air,...

Cardiac Exam III: Abnormal Heart Sounds
0 Views •

Source: Suneel Dhand, MD, Attending Physician, Internal Medicine, Beth Israel Deaconess Medical Center Having a fundamental understanding of normal heart sounds is the first step toward distinguishing the normal from the abnormal. Murmurs are sounds that represent turbulent and abnormal blood flow across a heart valve. They are caused either by stenosis (valve area too narrow) or regurgitation (backflow of blood across the valve) and are commonly heard as a "swishing" sound during auscultation.
FAQs
Pressure fluctuations arise as each wingbeat displaces air and drives unsteady aerodynamic forces. These forces can generate vortices and interactions between the wings and surrounding flow, producing changing acoustic signals rather than a single steady tone. Examining those changes helps connect the timing and character of sound with the mechanics of individual strokes.
Wing size, shape, beat frequency, and speed all influence the resulting sound spectrum. Size and shape affect how the wings interact with air, while frequency and speed change the timing of those interactions. Because several variables contribute simultaneously, interpreting acoustic patterns requires relating spectral features to the organism’s wing motion and flight conditions.
Beat frequency describes the repetition rate of wing motion, but it does not account for wing geometry or flight speed. Wing size and shape also modify air displacement, vortex formation, and flow interactions, which contribute to the spectrum. Consequently, a meaningful interpretation considers the combined acoustic effects of motion, morphology, and surrounding airflow.
Linking Wing Beat Sound with wing motion provides an acoustic route to studying flight dynamics without relying only on direct physical observation. The relationship can improve models of aerodynamic performance by associating measured acoustic patterns with the forces and flow interactions generated during flight. Those models may also support more informed autonomous flight control.
Distinctive acoustic patterns can provide noninvasive information for identifying and monitoring flying organisms. Analysts can examine the sound associated with wing motion and relate it to differences in wing size, shape, beat frequency, or speed. This approach is useful when tracking flight behavior or gathering information without physically contacting the organism.
Studying Wing Beat Sound shows how wing-driven pressure fluctuations carry information about motion and airflow. Bioengineers can use these relationships to inform the design of bio-inspired sensors and microphones intended to detect or interpret similar acoustic signals. The resulting devices can be shaped around flight-related information rather than treating sound as an isolated measurement.
Flapping-wing robots can use acoustic relationships identified in biological flight as a source of engineering guidance. Connecting sound patterns with wing motion and aerodynamic performance may help designers evaluate how a robot’s flapping behavior affects its surrounding flow. The same information can contribute to autonomous flight control strategies that respond to flight dynamics.
