Final answer:
Blind people are more accurate at locating sound sources with one ear plugged, while blind musicians are less likely to develop perfect pitch compared to sighted musicians. Blind individuals are more accurate at sound localization with one ear plugged and blind musicians are more likely to develop perfect pitch compared to sighted individuals.
Step-by-step explanation:
The question pertains to the abilities of blind compared to sighted people in pitch perception and sound localization. Studies have found that blind people are often more adept at certain auditory tasks due to their reliance on hearing to compensate for the loss of sight. Therefore, when it comes to localizing sound sources, blind people can be more accurate than sighted people, even with one ear plugged. Musical training is also affected by visual impairment; often, blind musicians are more likely to develop perfect pitch, an ability to recognize and reproduce specific pitches without reference tones, due to their enhanced auditory perception.
Based on these facts, the correct answer is:
