Bacause they can't
These sounds have got a specific name. They are known as Ultrasounds. We can hear them, but the problem is that they cause the eardrum to vibrate too much and hence they are incomprehensible.
One example problem involving sound waves could be calculating the frequency of a sound wave given its wavelength and the speed of sound in a medium. This can be done using the formula: frequency = speed of sound / wavelength.
To find the frequency, use the formula: frequency = speed of sound / wavelength. Assuming the speed of sound is 343 m/s, the frequency of the sound wave would be approximately 229 Hz. Yes, this frequency is within the audible range for humans, so you would be able to hear this sound.
The sound that you hear.
they cant hear but they can hear vibrating so they seem to know that its its enimie
because their ears are more developed.
Squat. Adults sit, or bend over...but they don't squat. Children can hear high frequency sounds that adults cannot. Most adults cannot hear tones above 13,000 Hz
Yes, pigs can hear tones from about 40 Hz up to 40KHz. See related link.
It depends very much on the sound pressure level the sound makes at the ears. Adults can often not hear sine tones higher than 15 kilohertz.
I think that humans can hear low frequencies the best because they travel farther and the wave form is wider. High frequencies break up easily against walls and buildings. Think about a loud car stereo on your street.
Teens and dogs may be able to hear certain sounds, such as high frequency tones, that are outside the range of hearing for adults. This is due to differences in the sensitivity of their auditory systems to higher frequencies. As people age, the ability to hear high frequency sounds typically decreases due to natural changes in the inner ear.
You hear 'beats', or pulses, and these pulses happen at a frequency which is the difference between the frequencies of the nearly identical tones.
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
The highest frequency that a human can typically hear is around 20,000 Hz. However, this ability tends to diminish with age, and many adults can only hear frequencies up to around 16,000-18,000 Hz.
You'll tend to hear sharp noises since the key tones being heard are on a higher frequency.
Adults, usually older than 30, cannot hear some of the frequencies that younger people can. It is usually a symptom of age.
i tones because there was no way to hear tones
