Answer :
Final answer:
Yes, a person can hear a sound at a frequency of 115 Hz if they classify it as such, as it is within the normal range of human hearing.
Explanation:
In physics, we understand that sound is a vibration that travels through the air or another medium and can be heard when it reaches an ear. The frequency of a sound wave affects its pitch. A frequency of 115 Hz, which seems to be referred to in point 115a., is within the range of human hearing and, therefore, a person can hear a sound at that frequency under normal conditions.
However, the collection of numbers and statements provided suggests that speakers and hearers can create and apply new categories while communicating, recognizing and distinguishing sounds in the process. This points to the fact that just as a speaker can emit sounds across various frequencies, the hearer can discern those frequencies, implying that a person can indeed hear a sound at 115 Hz if they classify it as such.
Lastly, the reference to a hundred hearings versus one seeing alludes to the richness of auditory learning, reinforcing that auditory processing and comprehension are vital senses, capable of distinguishing a wide array of sounds, including a 115 Hz frequency.
