Final answer:
In a hearing competition against old Dr. Beer, you would most likely win in the high-frequency range since human hearing ability deteriorates with age, particularly at higher frequencies (C).
Step-by-step explanation:
When considering a hearing competition with someone who is presumably older, such as old Dr. Beer, you would most likely win in the high frequencies range. This is due to the fact that human hearing ability tends to decline with age, particularly in the ability to hear higher frequencies. The normal range of human hearing is 20 Hz to 20,000 Hz, but we often don't utilize the full range, especially frequencies above 8000 Hz which are less common in our environment and not necessary for understanding conversation or music.
As we age, hair cells located near the base of the cochlea that respond best to high-frequency sounds, deteriorate and this results in difficulty hearing those frequencies. Hence, in a hearing competition against an older individual, a younger person typically has better hearing at higher frequencies. Additionally, humans tend to be especially sensitive to sounds in the mid-range frequencies which are most common in speech and environmental sounds.
