In vaccum there is no sound.
The loudness of the sound has no effect on its speed.
The atmospheric pressure has no effect on the speed of sound when the temperature is constant. The air pressure has no influence on the sound.
Air pressure does not affect transverse sound waves. The temperature is most important to do that. The speed of sound in air is determined by the air itself and is not dependent upon the amplitude, frequency, or wavlength of the sound. Look at the link: "Speed of Sound in Air and the effective Temperature".
A substance thru which an effect is transmitted from one thing to another, as air is the common medium of sound.
I assume you meant "density" More dense materials, such as solids, generally carry sound faster than less dense materials such as air
Yes, it is very likely for rhinoplasty to effect the sound of your voice. Because the nasal passages are altered during the procedure, the air through the nasal cavity will resonate differently and will therefore change the sound of your voice. If the procedure is minimal, the change may not be noticeable.

No because sound travels by vibrating the air. When the vibrations hit the inside of the bottle, they bounce off of the walls for a while, and will eventually lose momentum and their effect.
Temperature is important in sound waves because of air pressure(density).Air pressure regulates the ability for sound waves to be passed in a domino effect upon/through the atmosphere. A higher air(and higher temperature) pressureproduces a lower pitch frequency of sound wave because the density of atmosphere is low from high temperature. A good description of the effect of sound waves frequency of pitch relating atmospheric pressure can be found by investigating an effect called the "Doppler Effect(or Doppler Shift)"(named after theorist Christian Andreas Doppler) by which sound waves sound a lower frequency because of their compression(by approach against the standard speed of sound) before a moving sound producer/source passes and as it gets further away after it passes the pitch becomes higher purely because of the reverse of compression by speed(re standard speed of sound).
The speed of sound is not greatly affected by pressure in an ideal gas. Air is not an ideal gas, so there may be some small effect, but temperature and humidity will be much more influential. ================================ Answer #1: The frequency of sound is completely determined by the source of the sound. Once the sound leaves the source, the frequency doesn't change.
No change in frequency or wavelength.
There would be no sound. Sound requires a medium, like air, or water or anything with mass to propagate the wave that causes the vibration in the ear that produces the effect of sound in the brain. If you put your ear or more likely, the helmet of your spacesuit against the drum, the physical contact would transfer the vibration to the air in you helmet and then to your ear, enabling you to hear the sound.
