Verified step by step guidance

Step 1: Begin by understanding the primary function of the outer ear in the auditory system. The outer ear consists of the pinna (auricle) and the external auditory canal, which are designed to interact with sound waves.

Step 2: Recall that the pinna helps to collect sound waves from the environment and direct them into the external auditory canal. This is the first step in the auditory process.

Step 3: Consider the role of the external auditory canal, which amplifies certain frequencies of sound as the waves travel toward the tympanic membrane (eardrum). This amplification is a secondary function of the outer ear.

Step 4: Note that the outer ear does not interpret sound or transmit electrical signals. These functions are performed by other parts of the auditory system, such as the inner ear and the brain.

Step 5: Based on the above information, identify the correct answer by focusing on the primary functions of the outer ear: collecting and amplifying sound waves.
