Bats and dolphins both hear a ______ than humans do...

a.smaller range of pitches
b.smaller range of frequencies
c.larger range of resonances
d.larger range of pitches and frequencies

I am not certain exactly what a 4th grade teacher is supposed to be doing with this subject, but there is NO difference in pitch and frequency in common usage. Either a, or B is correct.

I'm 4th grade and I know nothing of bats and dolphins. This is a question of my spring packet.

The difference between pitch and frequensy is frequency is the characteristics of a wave length, and pitch is the result that we hear depending if it has a high or low frequency.

Bats and dolphins both hear a larger range of pitches and frequencies than humans do.

To understand this, we need to know a little bit about the hearing capabilities of bats, dolphins, and humans. Humans can typically hear sound frequencies ranging from 20 Hz (low pitch) to 20,000 Hz (high pitch). Bats and dolphins, on the other hand, have evolved to hear at much higher frequencies.

To find the answer to the question, we can rule out options a and c because both bats and dolphins can hear frequencies outside the range of what humans can hear. This leaves us with options b and d.

To determine if either bats or dolphins have a smaller or larger range of frequencies compared to humans, we can look at scientific research or studies that have measured the hearing capabilities of these animals. Various studies have shown that both bats and dolphins are capable of hearing ultrasonic frequencies well beyond the range of human hearing.

Therefore, the correct answer is d. Bats and dolphins hear a larger range of pitches and frequencies than humans.
