Vocal Range Extremes: While the average human vocal range spans about two octaves, some individuals, like Tim Storms, can sing notes as low as the subharmonic F-1, which is so deep it's barely audible.
Voice Prints as Unique as Fingerprints: Just like fingerprints, each person's voice is unique. Voice recognition technology can even identify individuals based on their vocal patterns.
The Sound of Space: In space, there is no air to transmit sound waves, so astronauts can't speak in the traditional sense. Instead, they use radios to communicate.
The Infrasonic Whisperer: Some animals, like elephants and whales, communicate using infrasound, which is below the human hearing threshold. Elephants, for instance, can communicate with infrasonic rumbles that travel for miles.
The Ultrasonic Voice: Humans can only hear sounds within a certain frequency range, typically up to 20,000 Hertz (Hz). Bats, on the other hand, use ultrasonic vocalisations that are beyond our hearing range for echolocation.
The X Factor: In 2008, a Scottish woman named Joy Milne shocked scientists when she claimed she could smell Parkinson's disease on people. Her unique ability was later linked to subtle changes in a person's voice and body odour associated with the disease.
The Songbird Brain: Certain songbirds like the European Starling are capable of mimicking a wide range of sounds, including car alarms and camera shutters, by altering the shape of their vocal tract.
The Power of Whispering: Whispering can strain your vocal cords more than speaking at a regular volume. It requires the vocal cords to be stretched and controlled with great precision.
Voice Synesthesia: Some people experience voice-color synesthesia, where they perceive specific colors associated with different voices. Each voice triggers a unique visual sensation.
