HEARING SYSTEM

Hearing is the ability we have to receive sounds. These can be bass and treble.
For this ability to take place we have the hearing system.
Parts of the hearing system:

• outer ear: this is the part we can see. It's mainly the ear and eardrum and we use it to receive sounds
• middle ear: this part is a small air chamber and helps to take vibrations from outer ear to inner ear. We cannot see this part.
• inner ear: this part helps to take vibrations from middle ear to the brain and helps the brain to translate these vibrations into instructions and signals.
• Neuronal: it's the part of the brain that translates vibrations initially captured by the outer ear. The sound travels from the cochlea via the auditory nerve to the brain so it can translate them into signals or instructions that we can understand or recognize.

Humans and animals have hearing systems
Not all sounds are audible to all animals and humans. It dependes on the amplitude and frequency of the sound.
For example, dogs can hear sounds that we can't hear. We can blow a whistle that we can't hear but dogs can.
Sounds are different if you are under water, as sound is transmitted differently in air and in water.
Hearing system is impacted by pressure changes. If you are in deep under the water or if you are flying in a plane your hearing system (eardrum mainly) can hurt.
If you have a cold, your hearing system can be impacted as it's also connected to your top respiratory system.
Hearing system can affect your balance as it's connected to your brain. If you have an infection in your hearing system you could fall down.
Hearing system is very helpful for humans and animals to be able to communicate and interact with the environment, but it's also very sensitive.
