The solution to the problem we mentioned above is voice recording. By recording the car, we can reduce the extra sounds, vibrations, etc. When sounding, all parts of the car are checked, but the most important items that often need sounding are the pillars, dashboard, trunk, roof, doors, steering frame and ventilation system.
The importance of car sound recording
Suppose you are driving and these extra sounds and vibrations keep bothering you. If this happens every day, chances are you'd rather walk than drive! If you are one of the people whose daily activities depend on using a car, it will be more difficult for you to bear such conditions. So what you should do as soon as possible is to do the sound recording. To do this, we must first find the source of the sound. The creation of additional car noises often boils down to one of the following three factors:
Sounds caused by the engine and mechanical parts
Noises caused by cabin parts
Ambient and road-related sounds
Squealing or screeching of belts
One of the common sounds that can be heard inside the cabin is the screeching sound of belts. The main causes of such a sound when the car accelerates are:
Low flexibility of belts and their poor quality material
Old or dry belts
Loose or tight tensioner belt roller
Friction between the foley and the belts
If you act early to repair belt problems, you can fix them at a small cost. For example, by adjusting the tensioner belt, or replacing a damaged belt, its excess noises can be eliminated. If the problem is with the timing belt and if it breaks if it is not taken care of, it will cause serious damage to the car engine and it will cost you a lot.
Whining sound when turning the steering wheel
You may have heard a whining sound from inside the hood when turning the steering wheel. Such a noise is related to the hydraulic power steering pump. In this case, you can assume that either the hydraulic oil level is low or the o-rings inside the pump are damaged. Adding a little oil or air bleeding can solve the problem and prevent heavy costs later on.
Knocking or roaring sound from inside the car engine
Sometimes when starting the car, a regular roaring sound is heard, especially in cars with high valve stems. This noise may disappear as the engine warms up and revs up, but it can still be heard sometimes. In such a case, you can assume that this sound is caused by the failure of the typewriter or excessive relief of the valves. Therefore, the typewriters must be replaced.
This type of sound is caused by what happens inside the cylinder. If the car's spark plug is damaged or the air-fuel mixture is not balanced, incomplete combustion will occur and an explosion will occur inside the cylinder. Incomplete combustion makes the car unable to move smoothly. Therefore, in addition to producing annoying sounds, it will also cause problems in driving and controlling the car.
Faceface sound under the engine door
Hearing this sound shows us that there is a leak somewhere. In such a case, the coolant, i.e. water and antifreeze, is leaking, which causes the radiator water to decrease, and for this reason, the car engine boils. You must act quickly to fix this problem, because there is a possibility of burning the engine or damaging the cylinder head. The failure of the vacuum tube also causes a sharp increase in fuel consumption. Of course, this leak may be from the cooler pipes, which puts a lot of pressure on the compressor.
Whistling sound when braking
If you hear a whistling sound when braking, you should know that the pads are worn out and need to be replaced.
Gearbox noise when changing gears
This problem is related to the clutch. The car's clutch is either out of adjustment, or needs to be replaced. Also, not adjusting the gear lever, leakage and lack of gearbox viscosity, and loss of brass gears are other causes of gearbox failure. The manifold in the car is responsible for air intake and exhaust of smoke from the cylinders and is one of the main components of the ignition system. The o-rings and gaskets inside the manifold crack after working for a while and heating and cooling. When this happens, the engine vibrates at low revs and runs poorly. Preventing this problem is not difficult, and it is enough to replace the o-rings every four years.
Racking noise from the side of the tires
If you are driving at low speed and you hear a clicking sound when you turn the steering wheel, it is likely that the Pulus is damaged. Of course, we recommend checking other parts of the car's suspension system as well.
Sound caused by electrical parts
Sometimes the sound is caused by the electrical parts of the car. For example, wipers, heaters, relays, injectors, etc. can all make noise. Once you identify which part the sound is coming from, check it and repair if necessary.
Sounds caused by the cabin itself
When the car gets old, the components inside the cabin also make noise. We've probably all heard the rattling sound of seats, especially the front seats of older cars. When recording, these types of sounds are also removed.
