Answer :
Final answer:
In the 'cone of confusion', it is difficult to localize sounds because two sound sources have the same interaural time differences and the same interaural level differences. These parameters can create ambiguous sound source locations.
Explanation:
In the 'cone of confusion', we have difficulty localizing sounds because two sound sources can have the same interaural time differences and the same interaural level differences. This is option (c).
The 'cone of confusion' refers to an area where, due to the physical nature of sound waves and the structure of our ears, it can be hard for us to pinpoint the exact location of a sound.
'Interaural time differences' refer to the time difference of a sound arriving at one ear versus the other. Similarly, 'interaural level differences' refer to the difference in loudness and frequency distribution of a sound at one eardrum as compared to the other.
When these parameters are the same, it generates ambiguous sound source locations, creating what we refer to as the 'cone of confusion'.
