Question

1. Compare two ways we locate sounds with binaural cues. (There are three but ignore phase). Be sure to comment on: i. whether each way is better at low/high frequencies, ii. what kind of neural processing is required, and iii. where that happens in the brain. [4 pts]

Answer 1

The main two ways we locate sounds through binaural cues are the interaural level difference and interaural time difference. These two ways are slightly different due to a different process, frequency and are where it happens in the brain.

In the process of listening, the sound is perceived by both ears. This involves a complex process because the frequency of the sound might be slightly different in both ears.

In this process, the cues or information that help the brain understand where the sound is coming from are known as binaural cues. Based on this, there are two main ways we locate sounds:

Interaural level difference: This occurs as the source of the sound will be closer to one ear than another. This binaural cue process implies ears detect different levels of loudness. Moreover, this process has the following characteristics.

• It is used mainly for high-frequency sounds.
• It is processed in the mid-brain and the auditory brain stem.
• It implies the ear detecting the sound and then specific areas of the brain processing this sound.

Interaural time difference: This occurs as the sound is perceived by each ear at a slightly different time, due to the distance between one ear and the other. This process has the following characteristics:

• It occurs for both high and low-frequency sounds.
• This process occurs mainly in the mid-brain.
• Similar to the first type of biaural cue it involves the perception from the ears, and then the sound is processed in specific areas of the brain.
