Could be a worn CV joint
A seized gear can cause a knocking sound on a 1987 Nissan 5 speed transmission. A blown gasket can also cause this sound.
It is all about the nature. Temperature causes the sound speed.
the tires themselves.
My 2000 Grand Prix would have a low-speed knocking noise coming from the drivers side as the CV axle was failing. The loss of lubrication in the CV Boots allows the joint to make a knocking/tapping sound at a low speed. If the knocking is coming from the engine compartment, then it could be an entirely different problem.
possibly hitting the front bumper
it sounds like a bad throw out bearing or clutch plate. not a major deal it just starts to get louder but eventually you going to have to replace it when you do your next clutch job. chris
No such thing as supersonic sound. Things can move with supersonic speed (fighter jets, ends of whips) making a shock wave, but the sound arrives at your ears at the speed of sound.
Sound travels faster in water than in air, which changes the way the sound waves travel through the medium. This difference in speed and density causes the pitch and tone of the sound to be altered, making a person's voice sound different underwater compared to in the air.
It displaces oxygen/air in your lungs because H is heavier then oxygen/air. Therefore changing the characteristics in how you sound.
When travelling faster than the speed of sound (supersonic speed), a sonic boom is created. This is a loud noise produced when an object passes through the air at a speed greater than the speed of sound. It can be disruptive and can lead to regulations on supersonic flight over populated areas.
Wind speed can affect the perceived frequency of sound waves due to the Doppler effect. If the wind speed is moving in the same direction as the sound, it can increase the perceived frequency, making the sound seem higher in pitch. Conversely, if the wind speed is moving in the opposite direction, it can decrease the perceived frequency, making the sound seem lower in pitch.
The speed of sound is directly proportional to the temperature of the medium. This is because temperature affects the average speed of the molecules in the medium, which in turn affects how quickly sound waves can travel through it. As temperature increases, the speed of sound also increases due to the higher molecular activity.
