Question

Which part of the human ear recognises the quality of the sound i.e. loudness an pitch??

Answer 1

Cochlea is the part of ear in the shape of a snail. It is the inner portion of the year and cochlea in Greek means snail. The cochlea receive the sound waves in the form of vibrations causing the sterocilia to react which are small structures.
Steriocilia then turns these vibrations into impulse that are transmited to the brain
So larger the sound frequency larger will be the vibrations produced by it
