Question

science question of chapter sound and noise

Answer 1

We know that we hear by the help of ear, since ear need vibration to affect the cochlea.

We also know that thier is no atmosphere on the moon, so no medium to carry any vibration to our ear, and thus Two astronauts can't hear each other on the moon.

Answer 2

HELLO FRIEND HERE IS YOUR ANSWER,,,,,,

Sound is a particulate wave or the one producing waves and it needs a medium or a media for travelling and normal communication. No atmosphere and media present, no transmitting of voices.

Sound in fact is the one which emits those waves and should be located as per the compressed form and directed towards the medium for further interpretation on epoch signals it has obtained to be called as "Sound".

Basically, two astronauts, say a rotating orbital natural satellite or our Moon it'll need a medium to carry or load it over for some distance say "x" from the starting point or transmitter or emitter to a ending point a acceptor or a receiver by various encoded forms by compression and de-compression forms.

A sound further travels into the middle ear snail-like or shelled-like organ to which sound waves just enter the ear and full on strike the tympanic membrane or in simple words eardrum, eventually to vibrate in a compressed formed molecular and atomically defined structure (or causes them to vibrate). All small bones present in the middle ear try to transmit or send the sound in a modified and amplified vibration to fluids present in the cochlea, this creates pressurised compression into those fluids present in cochlea besides the narrowing shaped canal into a fairly or like a coiled organ or a coiled-tube like organ. Those canal then run over to main chambers supported by some elasticular membranes along lengths of cochlear organ. They are called basilar membranes which are highly differentiating and are extremely hard at broad Base and to the contrary very soft and smooth in the inner membranes (flexible too). Properties of this elastic membranes allow the sound waves to start into it and after transmitting is complete, they quickly finish off. Varying sounding frequencies are tested at peak positioned differences sticking with those membranous basilar linings. Many tiny sensory cells are usually attached towards it contains small minute hair structures that are taking part in this.

This while process of transmission of sound waves require a medium to transport these waves and to produce vibrations.....

HOPE THIS HELPS YOU AND CLEARS THE DOUBTS FOR SOUND TRANSMISSIONS WITHOUT A MEDIA IS NOT POSSIBLE!!!!!!
