Introduction
The Dacia Sandero is one of the best-selling small cars thanks to its excellent quality-price ratio. However, one of the critical points reported by owners concerns the poor soundproofing of the passenger compartment , which can make driving less comfortable, especially at high speeds or on uneven surfaces. In this article we analyze the main causes of noise, possible solutions and the best products to improve the soundproofing of the Sandero.
The Main Causes of Cabin Noise in the Dacia Sandero
1. Factory Sound Insulation
The Dacia Sandero is designed to be economical, which means that the sound-absorbing materials used are minimal. The sheet metal is thinner than higher-end models, and there is limited insulation in the door panels, roof and bonnet.
2. Rolling Tire Noise
The friction of tires with the asphalt can generate an annoying noise, especially on rough surfaces. The level of noise also varies depending on the type of tire used. Cheap tires or tires with a hard compound tend to be noisier.
3. Bodywork and Dashboard Vibrations
Some Sandero models have vibrations in the interior plastics, which amplify the noise perceived in the passenger compartment. This problem is common in economy cars and can worsen over time as the couplings of the interior parts wear and relax.
4. Engine and Exhaust System Noise
The engine, especially in diesel or LPG versions, can be noisier due to poor soundproofing of the engine compartment. In addition, the shape of the exhaust can transmit vibrations inside the car. The position of the engine mounts and their quality also influence the transmission of noise to the passenger compartment.
5. Aerodynamic noises
At highway speeds, wind hitting the windshield and side mirrors can create an annoying hissing sound, due to the presence of less effective seals than higher-end cars. Door and hood seals can lose effectiveness over time, increasing perceived noise.
How to Reduce Noise on Dacia Sandero
1. Install Sound-Absorbing Materials
One of the most effective solutions is the application of soundproofing materials. The strategic points to be addressed are:
-
Doors: Use dynamat panels or similar materials inside door panels to reduce wind noise and vibration.
-
Floor and Flooring: Place sound-absorbing mats to reduce road noise.
-
Wheel arches: Apply sound-absorbing materials to the wheel arches to reduce tire rolling noise.
-
Hood and Engine Bulkhead: Install a sound-absorbing mat under the hood and on the bulkhead separating the engine from the passenger compartment to reduce engine noise.
-
Roof: Adding a layer of insulation material to the roof reduces the propagation of external noise and also improves thermal insulation.
2. Use Quiet Tires
The choice of tires greatly affects the perceived noise. Some tire models have an optimized tread to reduce rolling noise. Among the best are:
-
Michelin Primacy 4
-
Continental EcoContact 6
-
Bridgestone Turanza T005
3. Improve Door Seals
The original seals can be replaced or supplemented with additional rubber seals to reduce external noise and aerodynamic hiss. Installing rubber profiles along the edge of the doors can significantly improve insulation.
4. Tighten and Lubricate Plastic Parts
Vibrations in the dashboard and doors can be eliminated with:
-
Adhesive felt tape between plastic joints.
-
Lubrication with silicone spray to reduce friction and creaking.
5. Improve the Soundproofing of the Trunk
A lot of noise comes from the luggage compartment. By applying sound-absorbing panels to the floor and side walls, acoustic comfort can be improved.
6. Check and Tighten the Exhaust System
A poorly fitted exhaust system can cause annoying vibrations. Regular checks and installing better silent blocks can help eliminate the problem.
Conclusion
The Dacia Sandero is an economical car but it can be improved in terms of sound insulation. With some measures such as installing sound-absorbing materials, choosing silent tires and improving the seals , it is possible to significantly reduce interior noise. Investing in good insulation significantly improves the driving experience, making it more comfortable and enjoyable.
