5 solutions to reduce car noise

All the noises that a car makes, can sometimes be “calls for help”. Therefore, it is very important to identify their source and identify their cause and not just reduce the noise level. Sometimes it can be difficult to find a fault, but most noises are cataloged and should be recognized by an experienced technician.

However, there is a special type of noise that is emitted inside the passenger compartment, which has nothing to do with a malfunction of the vehicle (or any of its systems) and which can be annoying to passengers.

In particular, they can cause discomfort in those who have a car of the latest generation, where noise isolation in the cabin is important to avoid that noise interferes with voice control.

Car Noise Reduction

When a car is aging, it is normal that there are distortions between parts that cause noise, such as ringing, creaking, crickets, etc. The following are solutions to the five types of noise that can occur in a car:

1. Ringing in door trim.

   Speakers cause vibration in the door trim, especially if they work with bass. To remedy this situation, it is necessary to check that the installation of these speakers is correct and, if this is not the case, such measures can be taken as fastening to the cladding or to the inner panel of the door, (special for the automotive industry) self-adhesive films and tapes to drown out these vibration and reduce noise.

2. Squeaking in the center console and dashboard.

   These sounds are very annoying because they come from a position close to the driver. One of the reasons for this situation is the wear of the stops between the plastic parts, as this creates friction between them. To solve this problem and reduce the noise level, it is recommended to disassemble the parts and place the tapes from the felt in the friction zone that causes these noises.

   Another cause of cod can be a breakdown of any tab, anchor parts, plastic fasteners. To avoid replacing the component, this can be fixed with two-component epoxy glue.

3. Vibration of wires or electrical components.

   Cables and electrical components installed inside the dashboard may come off their mounts as a result of vibration or shock to the vehicle. In this case, to reduce the noise level, it is enough to open the area and re-secure the cable or component, replacing the mounting brackets if they were damaged. This can be tedious, because, sometimes, it involves the dismantling of various plastic parts of the panel that may be damaged during installation.

   It is also possible that the clips or fasteners, plastic parts were broken. In these cases, just like in the previous example, you can also use repair glue.

4. Hoot plastic parts of the outer surface of the vehicle.

   Bumper, screens, etc. outside the car can come off their mounts and make noise when driving at high speed.

   If the cause was the loss or damage of the fastening brackets, they must be replaced. If, on the contrary, the reason was the breakage of the part itself, depending on the extent of the breakage, it can be repaired, soldered or glued to avoid its replacement.

5. Whistling due to lack of tightness of the door.

   When the door does not close tightly, or when at the same time it is faulty, gaps appear in which air enters when the car moves. In some cases, this is air filtration, emits a hiss and annoys the driver and passengers.

   To solve this problem and reduce noise, it is recommended to reinstall the hinges (or replace if worn).

   Door seals are exposed to moisture and temperature changes, which can cause cracks and seals. Seal care is a maintenance measure and it is recommended that it be carried out regularly to ensure that the passenger compartment is airtight.

Conclusion

While new materials are being developed to dampen noise and improvements are being made to vehicle design and assembly methods, it is normal that over the years, the vibrations and temperature fluctuations a vehicle is subjected to cause breakdowns that produce extraneous noise.

However, thanks to the ingenuity and experience of car enthusiasts and plastic repair devices, it is possible to fix this type of failure and reduce noise quickly, avoiding costly repairs.
