It is almost impossible to define music. However, most describe it as significant arrangement of sounds.


Flies are not able to hear any sounds at all.


Most white cats that have blue eyes are often unable to hear sounds and are usually deaf.


Dolphins are capable of hearing sounds underwater from as far as 15 miles away.


Whale voices are able to travel a whopping 479 miles through the waters of the ocean. They have the ability to communicate with each other for long distances.


Most animals use sounds to help them detect dangers and hazards before they happen to them.


Our ears are able to hear distinct sounds because the vibrations which enter through them also ends up in our ears vibrating.


Sound is unable to travel via a vacuum because a vacuum is empty of matter.


Acoustics is known as the scientific study of sound waves.


Sound travels at a speed of around 767 miles per hour.


The majority of cows which listen to music end up producing more milk than those that do not.


In order for a whip to crackle or make the noise it creates, it must travel faster than the speed of sound.


Alarm systems transmit sound at around 1 to 3 kHz. That frequency range is both very sensitive for human ears and creates a black spot for our sound location ability.


Musical sounds are uniform vibrations, while noises are irregular vibrations. Musical sounds distinguish themselves through pitch, loudness, intensity, quality, and timbre.


The speed of sound is about 1,130 feet per second in dry air at 68 degrees Fahrenheit.


A healthy young human ear can hear all frequencies from 20 to 20,000 hertz.


In contrast, a dolphin can hear and produce sounds up to 150 kHz which is 150,000 hertz. This means that there are several sounds dolphins make that humans can't even hear.


People who have Superior Canal Dehiscence can experience a symptom where they hear their body sounds at high levels, including hearing their own eye movements.


Due to the Doppler Effect, a musical piece traveling twice the speed of sound would be in correct time and tune but only backwards.


Whether it's an orchestra or a heavy metal band playing music at 120 dB, both will undoubtedly damage your hearing.


Since particles are closer together in water than air, sound can travel four times faster in water.


Horror filmmakers use infrared sound to induce anxiety, sorrow, and even heart palpitations.


People hate the sound of their own voice on a recording because we hear ourselves differently in our own heads.


Active noise-cancelling headphones use destructive interference to cancel out incoming sound, erasing the sound waves altogether.

Old television remotes used an aluminum rod and a hammer to make a sound above human hearing to change the channel or the volume.


Astronomers located a black hole 250 million light years away by making a B Flat note 57 octaves below middle C.


A British scientists discovered elephants are terrified of bee sounds and will flee when they hear them.


It's estimated that making a sound at 1,100 decibels would completely destroy the universe in a black hole.


Because electric cars are very quiet, they are required to have artificial sounds for safety reasons.


Sound can't travel through space because there aren't any molecules to vibrate.


In 1883, a volcanic eruption on the island of Krakatoa produced sound which shattered windows, shook homes, and were reported to be heard 160km away from the explosion.


Pistol Shrimp produce an extremely loud pop to stun their prey. The pop sound reaches 218 decibels which is louder than a gun shot.


Blue whales can make deep sounds up to 188 decibels and can be heard 500 miles away.


Research in psychoacoustics helps us understand how sound affects our psychology and nervous system.


Even if you aren't recording sound on a video recording, researchers at MIT found they can recreate a voice solely by the small vibrations of the things in the video recording.
