A person's perception of a word can be influenced by the way they see the speaker's mouth move, even if the sound they hear is unchanged. [10] For example, if someone is looking at two people saying "far" and "bar", the word they will hear will be determined by who they look at. [11]
They can hear higher-pitched sounds than humans or most dogs, detecting frequencies from 55 Hz up to 79 kHz. [ 17 ] [ 18 ] Cats do not use this ability to hear ultrasound for communication but it is probably important in hunting, [ 19 ] since many species of rodents make ultrasonic calls. [ 20 ]
In this article, I will explore what humans can hear, including frequencies, hearing in noise, directional hearing, and how it compares to an animal’s hearing ability.
It is one of the traditional five senses. Partial or total inability to hear is called hearing loss. In humans and other vertebrates, hearing is performed primarily by the auditory system: mechanical waves, known as vibrations, are detected by the ear and transduced into nerve impulses that are perceived by the brain (primarily in the temporal ...
The Sun is said to be extremely noisy, but we can’t hear it since sound doesn’t travel through space. Scientists at the University of Sheffield decided to use vibrations within our star's ...
In his experiments, the subjects were discovered to be able to hear appropriately pulsed microwave radiation, from a distance of a few inches to hundreds of feet from the transmitter. In Frey's tests, a repetition rate of 50 Hz was used, with pulse width between 10–70 microseconds.
Auditory stimuli are received by the ear one at a time before they can be processed and understood. It can be said that the echoic memory is conceptually like a "holding tank", where a sound is unprocessed (or held back) until the following sound is heard, and only then can it be made meaningful.

This can lead to a competitive advantage in a political debate, or by a journalist to provoke a strong response from an interviewee, and is known as "ambushing". Individuals in conflict often blindly contradict each other. On the other hand, if one finds that the other party understands, an atmosphere of cooperation can be created.
