Example Sentences
Recent Examples on the Web Ultra-low-noise MM phono stage with infrasonic filtering circuitry. 
Mark Sparrow, Forbes, 17 May 2022 The phono preamp also has an innovative circuit that suppresses the infrasonic noise present on all vinyl, without compromising bass response. Mark Sparrow, Forbes, 21 Sep. 2021 While blue whale calls can exceed 180 decibels – louder than the roar of jet airplane – most of their sounds are infrasonic, meaning the frequency of their sound waves falls below the threshold of human hearing. The Christian Science Monitor, 24 Jan. 2022 Even the Earth itself generates a continuous infrasonic hum. Jason Gregg, Smithsonian Magazine, 8 Sep. 2021 Nuclear-blast detectors picked up the signature of a new population of pygmy blue whales and the infrasonic rumblings of 1,001 rocket launches. Rafil Kroll-zaidi, Harper's Magazine, 17 Aug. 2021 The researchers found infrasonic signatures for up to 73% of these rockets, or 733. David Bressan, Forbes, 10 June 2021 The study offers few clues about how terns might do this, but other research suggests some migrating birds detect infrasonic weather signals or observe changing clouds. Joshua Rapp Learn, Scientific American, 1 Oct. 2020 For instance, hot lava flowing down the mountain essentially drained the lava lake at its summit, so there should be a corresponding shift in the infrasonic signature.
