What is the News? An Indian researcher has fabricated paper honeycomb and stronger polymer honeycomb structure as sound-absorbing panels that dissipate acoustic energy to low-frequency ranges. Significance of this research: Many traditional materials have been found to be good at controlling higher frequencies, but not at lower frequency ranges. However, natural beehives have been found… Continue reading Indian Scientists Develop Noise Control Panels Inspired by Beehives
