Ear rumbling is a voluntary control of the tensor tympani muscle in the ear, which can create a low-frequency rumbling sound. This muscle can be activated by focusing or tensing certain muscles in the head and neck, causing the eardrum to vibrate.
Vibrations cause sounds. A sound wave is the vibration of the air around whatever is "causing" the sound (aka, whatever is causing the vibration--a guitar string, vocal cords, the mechanics of a stereo, etc).
Your ear rumbling could be caused by a muscle in your ear called the tensor tympani muscle contracting involuntarily. This can happen due to stress, fatigue, or exposure to loud noises. It is a common and harmless occurrence known as ear rumbling or ear fluttering.
There are a number of forces that could cause vibration in a ship. Friction for example is a force known to cause vibration.
It's called water-hammer. I vibration from the water pressure. A snub-end pipe can be added to devert the vibration.

Engine vibration can be an indication of a misfire, but more often it's just the AC compressor causing a little shaking.
Thunder is the loud crashing or rumbling noise heard after a flash of lightning. This happens because lightning heats the air around it, causing it to rapidly expand and create a shock wave that we hear as thunder.
Damped vibration. This occurs when energy is gradually dissipated, causing a decrease in amplitude over time. It is common in systems with friction or damping mechanisms.
Vibration when you talk is caused by air passing through your vocal cords, causing them to rapidly open and close. This vibration creates sound waves that travel through the air and are picked up by your ears as sound.
The rumbling sensation in your ears could be caused by muscle contractions in the middle ear, known as tensor tympani myoclonus. This can happen due to stress, fatigue, or loud noises. It is usually harmless but if it persists or is bothersome, it is recommended to see a doctor for further evaluation.
