Pinna

The pinna is a part of the ear made up of cartilage. It is also referred to as the auricle. 

The pinna is an important part of the auditory system. It helps to collect sound waves and direct them into the ear canal. This helps to amplify sound waves and make them easier to hear. In audiology, the pinna is often used to assess hearing. For example, audiologists may use a technique called tympanometry to measure the movement of the eardrum. Tympanometry is a test that helps to diagnose conductive hearing loss.

The pinna is also used in hearing aids. Hearing aids often have a built-in pinna simulator. This simulator helps to amplify sound waves in the same way that the pinna does. This can help to improve the sound quality of hearing aids.

What part is the pinna?

The pinna is the external part of the ear located on the side of the head.

What does pinna mean?

The word pinna comes from the Latin word pinna, which means “wing.” The pinna is shaped like a wing, and it helps to collect sound waves and direct them into the ear canal.

What is the function of pinna?

The pinna has several functions, including:

  • Collecting sound waves: The pinna helps to collect sound waves and direct them into the ear canal. This helps to amplify sound waves and make them easier to hear.
  • Directing sound waves: The pinna helps to direct sound waves into the ear canal. This helps to ensure that sound waves are received by the eardrum in the correct orientation.
  • Filtering sound waves: The pinna helps to filter sound waves. This means that it helps to block out unwanted sound waves and allow only the desired sound waves to pass through.

Why is it called the pinna?

The pinna is called the pinna because it is shaped like a wing. The word pinna comes from the Latin word pinna, which means “wing.”
