Explicación
## Step 1The problem is asking us to identify which type of sound is most likely to be first affected by the decline in hearing ability during middle age. The options provided are low-pitched, high-volume, high-pitched,## Step 2The human ear is more sensitive to high-pitched sounds than low-pitched sounds. This is due to the fact that the inner ear, which is responsible for hearing, contains hair cells that are more densely packed in the region that corresponds to high frequencies.## Step 3As we age, these hair cells can become damaged or die, leading to a decline in the ability to hear high-pitched sounds. This condition is known as presbycusis.## Step 4Therefore, the correct answer is C, high-pitched.
