big ears
they funnel in the sound waves from the enviroment
An elephant can use a low sound that is so low we can't even hear it
They make the noise from there trunk they just blow and that makes the sound. They also make noises in their body cavities (infra sound) that we can not hear which is propagated through the ground.
Elephants use their large sound collecting ears to hear sound. Elephant's ears are very important to an elephant because they serve many purposes, much more than hearing.
Yes they do their large ears channel sound like a blood hound's ears trap sent.
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.
The faintest sound people can generally hear is around 0 decibels. This is the threshold of hearing, also known as the absolute threshold of hearing, and represents the lowest intensity sound that can be detected by the human ear.
Most humans can hear sound frequencies as low as 20 Hz. Below this frequency, the sound may be more felt than heard, especially at very high volume levels.
The lowest frequency that a human can typically hear is around 20 Hz. Below this frequency, most people may not perceive the sound as a distinct pitch but rather as a sensation of pressure or vibration.
Infra-sonic refers to sound frequencies below the lowest human hearing range so are around 15Hz or lower. Many aquatic animals are able to sense low frequencies as a warning of approaching predators for example. Vibrations set up by fish or other marine dwellers travel for great distances. On land, many mammals are reported to react to very low frequency sounds such as those preceding earthquakes. Elephants use low frequency calls that travel for many mile to other elephants, mostly at frequencies below the range of human hearing.
It depends on age etc. but about 20 cps is the lower limit. (Some like to claim 16)
The lowest pitch a human can typically hear is around 20 Hz, although this can vary depending on factors such as age and hearing health. Below this frequency, the vibrations are felt as pressure rather than heard as sound.
