bone in the human body is in the ear!
The ossicular chain in the middle ear is composed of three tiny bones. They are responsible for delivering the sound energy from the external ear to the inner ear.
muscle of the human body is in the ear!
The stapedius muscle of the middle ear is responsible for controlling the ossicular chain and adjusting the sound energy input. It protects our ears from sudden loud noises.
organ of the body is the ear!
Our ears still work while we are asleep. They do not rest. That’s why we can hear the morning alarms and stay vigilant even in our dreams.
Hearing is the sense that develops the earliest and disappears the last. Hearing develops as early as the twentieth week during pregnancy. The ears detect and respond to sounds at the beginning of our life and accompany us all the way to the end.
Human hearing range.
The reason we are able to distinguish between different speaking voices or appreciate melodious music is because human ears are sensitive to volume, frequency, and timbre of sounds. Human ears can detect sounds in a frequency range from 20 Hz to 20k Hz and in a volume range from 0 to 120 dB HL. Isn’t it amazing?
Also, cats can detect sounds in an even wider frequency range from 25 Hz to 78 kHz. This means that they are able to hear much higher frequency sounds than we do!
