Dolphins and bats produce infrasonic sound whereas whale and elephant produce ultrasonic sound ( yes/ no)
Answers
Answer:
BATS
Bats emit calls from about 12 kHz to 160 kHz, but the upper frequencies in this range are rapidly absorbed in air. Many bat detectors are limited to around 15 kHz to 125 kHz at best.
DOLPHINS
The frequency of the sounds produced by a bottlenose dolphin ranges from 0.2 to 150 kHz. The lower frequency vocalizations (about 0.2 to 50 kHz) are likely used in social communication. Social signals have their most energy at frequencies less than 40 kHz.
WHALE
Humpback vocalizations, including the complex and wide-ranging “whale song” performed by males, typically have an audio frequency between 80 and 4,000 hertz (Hz). But the newly described pulse sounds were found to have a significantly lower frequency of around 40 Hz. The low limit for human hearing is 20 hz
ELEPHANT
The creatures produce low-frequency noises between 1 to 20 Hertz, known as infrasounds, that help them keep in touch over distances as large as 10 kilometers. A new study reveals for the first time how elephants produce these low notes.
