Check exhaust system for a leak Well, if it's a 2.0 SOHC engine commonly found in the 2000-2004 LX models, it's probably the EGR inlet tube. It looks like a copper tube running out of the front side of the engine, and hooks up to the exhaust manifold with a rectangular bracket held on by two bolts. The engine moves a bit under torque, and this part doesn't. It eventually develops a leak where the tube meets the bracket. You can probably fix it temporarily using JB Weld but it will eventually break again...
I read that bad motor mounts can cause this knocking sound
I hope so. However, if they see something that would be noisy on the Earth, but in space, like a rocket firing, they would not hear it in space, because sound needs a medium to travel through, like air. There is no air in space, it is mostly a vacuum. So the only sounds an astronaut should hear are his radio, his breathing and anything tapping on his helmet (the air in the helmet will transmit sound waves to his ears).
The best type of material that conducts sound the best would be any solid. Only because of the sound that hit the compacted atoms and it would travel the fastest.
As The jazz singer was the first movie with sound it would have to be that.(1927).
I would say dynamic, articulation, tone (as in intonation), and timbre
A retina has to be smooth and not wrinkled so the image that is formed by the lens is in focus at all points. If it were wrinkled, some areas of the image would be out of focus; it is smooth to best reflect the light.
If a person is in front of a smooth surface from which a sound is reflected, the person would hear a sound that ====================================================== Allow me to add(: SEEMS TO COME FROM BEHIND THE SURFACE:>
That would be the sound of your mother-in-law.
seems to come from behind the surface
If a Baja 180 is not running smooth and there is little power, it might be a dead cylinder. It is possible that a piston is broken which would cause the knocking sound and vibration.
The answer should seem to come from behind the surface.
All information needed for repairs are in owner manuals. For example, a diagram for a Ford Focus engine would be shown in the manual. Other information such as engine warnings of issues are addressed also.
An engine might sound like a diesel at operating temperature if the engine was a diesel or if there was an issue with the manifold. Sometimes gases escaping the manifold cover could cause the engine to sound different.
Engine rod? Engine bearing?
Faulty engine
the body on a guitar it used to ring out the sound. without the body it would not sound as smooth and not give the strings such a good sound. me knowing because i have played the guitar since i was 6.
In a 2000 Ford Focus SE : That would be the 2.0 liter , Single Over Head Cam ( SPI ) four cylinder engine
