How many hertz can a pigeon hear?
Pigeons can hear frequencies as low as .1 Hz, or one vibration every ten seconds! This allows pigeons to hear the infrasonic sounds of ocean waves breaking on the coastline. By positioning their flight path according to coastlines, pigeons can accurately navigate long migrations.
Describe infrasonic and ultrasonic waves and explain why humans can not hear them?
The human ear cannot detect all possible frequencies. It has evolved to detect frequencies of sounds that are the most useful to humans, and has a maximum frequency range of about 20Hz to 20kHz, which decreases as you get older, particularly at the higher end. Infrasonic describes sounds that are too low in frequency to be heard by the human ear, and ultrasonic describes sounds that are too high in frequency to be heard by the human ear. These sounds cannot be heard by the human ear because they are outside of its range of capability.
At what frequency is ultrasonic and infrasonic?
Human ears can hear frequencies between about 20 and 20,000 Hz, so anything below 20 is infrasonic, and anything above 20,000 Hz (20 kHz) is ultrasonic.
What is the Difference between pleasant and unpleasant sounds?
Pleasant sounds are nice to hear and unpleasant sounds are not nice to hear.
Why you can hear sounds better in air then you can underwater?
Sound moves faster and further in water than air, so it would seem like it must have something to do with the receiver. I'm guessing, but I'd guess it's because the eardrum evolved to hear sounds in air. Underwater you don't hear using the eardrum, you hear by way of bone conduction which apparently doesn't let you hear normal sounds as well as the air/eardrum method.
Which animals can hear infrasonic sound?
Animals that can hear infrasonic sounds are; frogs snakes ants dogs fishes whales beetles pigeons Usally, small animals can hear infrasonic sounds because they catches low frequency sound which is less than 20 Hz, especially insects. You may have observed that even if you walk very softly on the floor, animals like dogs feels your coming because they can hear infrasonic sounds.
Why does the cattle's ability to hear infrasonic frequencies contribute to a stampede?
The cattle's ability to hear infrasonic frequencies contributes to a stampede because these sounds are not heard by the cattle drivers and they are not able to react prior to the stampede. The continued sounds cause the cattle to keep running.
Can we hear earthquakes why or why not?
We cannot hear earthquakes from our ears. It is because the waves produced are infrasonic.
What is audible and inaudible sounds?
Inaudible sounds are sounds that you cannot hear. Audible sounds are sounds that you can hear. Frequencies capable of being heard by humans are called audio or sonic. The range is typically considered to be between 20Hz and 20,000Hz.[3] Frequencies higher than audio are referred to as ultrasonic, while frequencies below audio are referred to as infrasonic
Can humans hear the sonic range?
The Human hearing range IS the sonic range. Sounds which fall under the ultrasonic range are sounds which emit a higher frequency then we can hear (ie. dogs hear within this range). Infrasonic sounds emit lower frequencies then we can hear. The human hearing range or 'Sonic' range is between 16- 20 000 Hz, though changes with age
Why do you think cattle's ability to hear infrasonic frequencies might contribute to a stampede?
Cattle don't like high-pitched sounds. They are quite sensitive to it, and such sounds can cause a herd of cattle to flee away from such a sound.
Can humans hear infrasonic waves?
With special technology, yes
Are there sounds we can not hear?
Human hearing is most effective in the range of about 20 Hz to 20,000 Hz. Slightly lower frequency sounds may be heard or "felt." Some sounds outside this range can be heard by some individuals. Some animals have a wider range of hearing, such as dogs who can hear higher pitched (higher frequency) sounds.
What is infrasonic frequency?
These are frequencies less than 20 Hz (cycles per second) which represent sounds that most of us cannot hear. More information is available on the wikipedia article about infrasound.
How humans hear sounds using vibrasion?
yes
