By changing the frequency of the vibration. High frequency = high pitch. Low frequency = low pitch.
Low frequency = low pitch = long waves
It has a low pitch
Technology does come to the rescue here. Elephants for example give out vibrations far too low for humans to hear, but other distant elephants do hear the signal. (Similarly for some whales.) You can record these arbitrarily low frequency signals, and then play them back with the recording speeded up. You will hear "speeded up versions " of the elephants talk. This method is not a "real time" technique, for it requires the signal to be replayed after it was recorded. A "real time" method is to add the signal electronically to a carrier of say 5kHz. You will hear the low frequency signal as a modulation of the 5kHz signal. Our ears are very sensitive to 'Wow and Flutter' and the modulation of a signal of a few HZ will be heard. Reverting to the question, what you make of the elephant talk is up to you and your understanding of elephant culture and sociology. I can't help there.
No, infrasound is the frequency of sound that is too low for humans to hear, below 20 hertz, but is used for communicating by elephants and other animals. Echolocation is normally ultrasound, the frequency above our hearing range, higher than 20,000 hertz, and is used by bats and dolphins in echolocation.
yes they can. they is how they communicate
No
Both whales and elephants can hear extremely low frequency sounds.
for communication and mating calls
Elephants make a number of sounds. They make specific sounds related to sex and danger which we can hear and understand. However, they have a much larger number of sounds which are too low in frequency (infra sound) for our ears to hear which is propagated via the elephant's legs and feet through the ground over great distances. The most common sound (that we can hear) that elephants make is called trumpeting. We can also hear them make a low rumbling noise. Examples of this can be heard by clicking on the related link.
How to make Low frequency clock generator using ANAD gates?
Elephants have a wide variety of noises, including trumpeting with their trunks, but also make low rumbling sounds with their vocal cords (not their "tummy") that are subsonic and can travel for miles through the ground (they're seismic"). The sounds can be heard by other, distant, elephants through their feet and trunks. These low frequency noises are called 'infrasound'.
A Cougar Cub sounds much like a house cat, a simple Meow. It has a higher pitch, and, at the same time, very low. Very Interesting to hear :)
A surprisingly long distance as elephants are able to generate very low frequency sounds (i.e. infrasonic, frequencies that humans cannot hear at all) that can travel through the ground for many tens of miles and still be heard by other elephants.
Low frequency = low pitch = long waves
elephants need to hear better because they communicate* in a lower frequency which means we cant hear them communicate* but they need better ears so they can hear each other *they communicate in low frequency drone's like bird tweeting except they are a lot lower and we cant hear them
low
