What are three things that elephants have that help them make low sounds?

Elephants possess several anatomical features that enable them to produce low-frequency sounds. Firstly, their large larynx allows for the production of deep vocalizations. Secondly, the size and structure of their vocal cords are adapted to create lower pitches. Lastly, their unique resonating chambers, including their large nasal passages and skull cavities, amplify these low sounds, facilitating communication over long distances.
