The ears never stop working, the left ear hears music better than the right ear and feels comfortable when hearing laughter and boiling water.
The ear is responsible for hearing and maintaining the body's balance. The ear is a complex structure and every part must work at optimal frequency to transmit air waves to the brain. Here are some facts about the ear.
Ears never sleep
Our ears still hear the sounds around us when we sleep. However, we are often not aware of this because the brain is resting and shuts down its ability to hear, resulting in ignoring the sounds around us. Therefore, the ears only react to loud or unexpected noises as a defense mechanism.
Ear allergy to unpleasant sounds
A 2012 study by Newcastle University (USA) found that the most unpleasant sounds to the ear include the sound of a knife scraping against a bottle, the sound of a fork scraping against a plate, the sound of chalk rubbing vigorously on a blackboard, a baby crying, an electric drill, the sound of a rusty swing squeaking, a person vomiting and two pieces of expanded polystyrene rubbing together. Conversely, the most pleasant sounds were boiling water, children laughing and clapping.
Ear size grows over time
Ears come in many shapes and sizes, and men's ears are generally larger than women's. According to information from Texas Tech University (USA), ear circumference increases on average 0.51 mm per year, possibly due to changes in collagen.

Sound in the ear
The middle ear is connected to the back of the nose and throat by a eustachian tube. Most of the time, this tube is closed. Sometimes it makes a popping sound when we swallow, yawn, chew, or when we fly. This is because the eustachian tube is malfunctioning and does not open or close properly.
The two ears have complementary functions.
People with hearing loss in one ear often have difficulty recognizing where a specific sound is located. Therefore, they are often advised to use two hearing aids to identify warning sounds around them and navigate safely in traffic.
Ears are the "culprit" causing motion sickness
Any movement is sensed by the brain through various pathways of the nervous system including the inner ear, eyes and tissues on the surface of the body. Motion sickness occurs when the repetitive motion of a vehicle disturbs the inner ear, causing the central nervous system to receive conflicting messages from the ears and causing vomiting.
Ear hairs aid hearing
Tiny hairs inside the ear help us hear by transmitting sound waves to the brain. The brain then analyzes and understands the sound. Damage to the tiny hairs inside the ear can lead to permanent hair loss and hearing loss.
The left ear perceives music better.
Research from the University of California and the University of Arizona (USA) shows that the right ear often responds faster to speech from birth, while the left ear is more receptive to continuous sounds and related to pitch and music. The study was published in 2004, with data from more than 7,000 newborns.
