can't be answered sensibly w/o specifying the noise A cat's hearing range is unlimited, depending entirely on the volume of the sound that the cat may hear, the distance of the source of the sound from the cat, and the intervening terrain, foliage and construction.
Well, cat's have two modes of sleep. They have a very light sleep, where they are resting but only temporarily, a small noise that seems different to them will wake them immeadiately. They also have a deep sleep, which they go into when resting for long periods of time. They will hear large noises in their dreams, like humans do, but won't notice them. Their minds make an excuse for them, say they hear a bang in real life, something will make that sound in their dream and they won't notice it. You would have to make a cointinues or very loud noise to wake them, or touch them.
http://www.lsu.edu/deafness/HearingRange.html Animal Hearing Ranges from low to high.
It is generally accepted that a cat can hear as low as a human ~20hz.
Cats can hear high pitched noises up to 64 khz. Cats' hearing for low pitched noises is similar to humans hearing of low pitched noises.
Lower ~ pitched sounds
70mph
Loud enough to be heard from around 2 miles away.
Pigs can hear in audio tones in a range of about 40 Hz to about 40 KHz.
Of course not. Everyone knows that bats use echolocation because that they can't see very well. So, they use these high pitched screeches that bounce off of objects and back to them. This tells them if there is and object nearby, how close it is, and how large or small it is.
Cats. They can detect higher-pitched sounds than either dogs or humans. They can hear frequencies from 55 Hz up to 79 kHz, a range of 10.5 octaves, and humans can only hear from 31 Hz up to 18 kHz, and dogs can hear from 67 Hz to 44 kHz, which are both ranges of about 9 octaves.
A cats' hearing is much more sensitive than humans and dogs. A domestic dog's hearing range is approximately 40 Hz to 60,000 Hz, where is it thought that a cat's is 45 Hz to 64,000 Hz. This is compared to a human's hearing range of about 64 Hz to 23,000 Hz.
Domestic cats can hear sounds in the range of about 2 kHz to 65 kHz. The average hearing range for humans is about 02 kHz to 20 kHz. Therefore cats hear better than humans.
The range humans can hear is about 20 - 20,000 Hz (20 Hz to 20 kHz); the range is smaller for older people.
http://en.wikipedia.org/wiki/Audio Audio simply means sound, anything you can hear. The average frequency range of human hearing is from 20 Hz to 20 kHz.
Audio is Latin and means "to hear" in English.
The root word of "audio" is "audire," which is Latin for "hear" or "listen."
The hearing range of a cat is about 70dB - 10.5 octaves, around 1.6 octaves above humans. Humans and cats have a similar hearing range on the lower end of the scale but cats have more advanced hearing therefore can hear a lot more

You cannot see audio. You hear it.
Pigs can hear in audio tones in a range of about 40 Hz to about 40 KHz.

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
Anything that creates electrical sound (aka audio.) A piano is a sound generator but NOT an audio generator. An organ or keyboard is an audio generator and not a sound generator. These can also be thought of as signal oscillators in the 20-20k hz range which usually produce a constant signal or tone over a period of time. Sound is anything you can hear, and audio is anything you need an amplifier to hear.
