Frequency

What are Binaural Beats? The human brain creates “sounds that shouldn’t be heard” (beats) by playing slightly different frequencies to each ear. This phenomenon is called binaural beats. Binaural beats are a phenomenon where “the brain perceives the frequency difference” and occur through a brain function called FFR (Frequency Following Response). When you play, for example, 440Hz to the left ear and 445Hz to the right ear, a rhythm of that difference (5Hz) is generated in the brain, and you feel this beat. ...

Introduction The 52-hertz whale is a mysterious creature that continues calling at a frequency unlike any other whale. In 1992, the U.S. Navy’s underwater acoustic surveillance system (SOSUS) discovered a whale that calls at a distinctive frequency of 52Hz, much higher than typical blue whales (15-25Hz) or fin whales (around 20Hz). Known as “the world’s loneliest whale,” it has influenced marine biologists, acousticians, filmmakers, and writers alike. Does the 52Hz whale really exist? Is it truly lonely? I decided to investigate. ...
