Perception, though we believe is restricted to respective senses, in reality, is done through the coordination of the five senses along with mind(mind is taken as an organ in Indian Philosophy) .
We see through eyes because eyes are tuned in to the vibrations of the objects which we see, that is it is in the same wave length as that of the object.If the vibrations of the objects vary, then eye can not see.If the vibrations(energy radiation) of a particular object,that has to be heard, is in the range of eye’s vibration, then we see the sound.
Principle underlying the phenomena is the fact that energy is the underlying Principle and the difference between Matter and Energy is one of degree, not of kind.
Story:
A study found that inaudible puffs of air delivered alongside certain sounds influenced what participants thought they were listening to.
Writing in the journal Nature, the team said the findings showed that audio and visual clues were not the only important factors in how people hear.
The findings may lead to better aids for the hard of hearing, experts said.
It is already well known that visual cues from a speaker’s face can enhance or interfere with how a person hears what is being said.

If further research can show the same effect is observed when listening to everyday conversation in the ‘real’ world, then it could help improve hearing aids

In the latest study, researchers at the University of British Columbia in Vancouver wanted to look at whether tactile sensations also affected how sounds are heard.
They compared sounds which when spoken are accompanied by a small inaudible breath of air, such as “pa” and “ta” with sounds which do not such as “ba” and “da”.
At the same time, participants were given – or not – a small puff of air to the back of the hand or the neck.
They found that “ba” and “da”, known as unaspirated sounds, were heard as the aspirated equivalents, “pa” and “ta”, when presented alongside the puff of air.
