Gas, Solids, Liquids
The speed of sound depends only on the material it's traveling through, not on the source of the sound. In general, the speed is higher in more-dense media, like steel, water, and rock, then it is in less-dense media, like air.
Sound waves
longitudinal
The eardrum.
Materials that are able to transmit sound well includes solid. This is because the molecules within solids are closer together.
Elastic

Propaganda techniques can be transmitted through various forms of media, such as television, radio, social media, print advertisements, and online platforms. These techniques aim to influence public opinion, promote a particular agenda, or manipulate individuals' beliefs by employing strategies like emotional appeal, demonizing opponents, and spreading misinformation.
Outerspace has no sound. This is because outerspace is essentially devoid of matter, and matter is required for sound. Sound is a physical phenomenon of a travelling pressure wave, and in space there is essentially no gas or media to transmit a wave.
Sound and vibration are transmitted by matter. So a vacuum will transmit neither.
Sound waves
No. It does not transmit the sound waves.
Solid
yes
longitudinal
No
A cell 'phone does not transmit sound. It transmits electromagnetic radiation. Sound is converted to and from an electromagnetic signal by the microphone and speaker.
