Soundproofing <em>Nissan Note</em> - step-by-step guide with photos and tips

Owners Nissan Note often encounter increased noise levels in the cabin, especially at speeds above 80 km/h. This is due to the design features of the compact van: thin metal panels, minimal factory sound insulation and open technological holes. Noise from wheels, wind and engine not only tires the driver, but also reduces passenger comfort.

In this article we will look at all stages of sound insulation - from the choice of materials to the treatment of specific areas of the body. You will learn which areas require priority attention, how to avoid common mistakes and how long the process will take. The material is relevant for all generations Nissan Note (E11, E12), including restyled versions.

Why Nissan Note so noisy: analysis of weak points

The main sources of noise in Nissan Note are divided into three categories: aerodynamic (wind), structural (body vibrations) and road (from wheels and suspension). Factory sound insulation of the model is minimal - the manufacturer saves on weight and cost, which is especially noticeable in the basic configurations.

The most problematic areas:

• 🚗 Cabin floor — thin metal and lack of vibration isolation transmit all the impacts from the wheels.
• 🔊 Wheel arches — open cavities resonate the sound from the tires, especially on dirt roads.
• 💨 Doors - poor sealing and lack of seals at the joints.
• 🔧 Motor shield — engine vibrations are transmitted into the cabin through a thin partition.
• 🌬️ Roof and pillars - create turbulent air flows at speed.

According to test results, after complete sound insulation the noise level in the cabin Nissan Note decreases by 12–15 dB (depending on the materials used). This is comparable to crossing from a highway onto a quiet city street.

Sound insulation materials: what to choose for Nissan Note

The choice of materials depends on the budget and goals. For budget processing Vibroplast and Shumka are enough, but for maximum effect a multilayer system will be required. Below is a comparison table of popular solutions.

Material type	Examples of brands	Thickness	Purpose	Cost (per 1 m²)
Vibration isolation	StP Aero, Vibroplast Silver, Bitumast	1.5–3 mm	Damping metal vibrations	300–800 ₽
Noise insulation	Accent Premium, Splen 3004, Bimast Bomb	4–10 mm	Airborne noise absorption	200–500 ₽
Anti-creak	Madelin, Body 950	0.5–1 mm	Eliminating plastic squeaks	150–300 ₽
Sealant	Terostat 922, Bostik MS Polymer	—	Sealing seams and holes	400–700 ₽

For Nissan Note optimal two-layer complex: vibration isolation (2 mm) + Shumka (8 mm). For example, the combination StP Aero (vibration) and Accent Premium (Shumka) gives a balanced result in terms of price and efficiency. For wheel arches it is better to use Bimast Bomb — it is resistant to moisture and mechanical stress.

⚠️ Attention: Do not use cheap bitumen vibroplast on plastic panels - it can melt in the summer and ruin the cladding. For doors and roofs, choose rubber-based materials.

Step-by-step instructions: soundproofing the interior floor

Floors are the main source of road noise in Nissan Note. Its processing gives up to 40% of the total effect from sound insulation. The work is carried out after removing the seats, mats and plastic covers.

Remove seats and mats

Clean the metal from dirt and rust (if necessary)

Degrease the surface with alcohol or anti-silicone

Prepare materials (vibration + noise) and tools (roller, hair dryer)

Seal the technological holes with tape (if access is not required) -->

Work order:

1. Paste vibration isolation (For example, StP Aero) on the entire metal floor with entry to the thresholds. Heat the material with a hairdryer and roll it tightly with a roller. Pay special attention to the areas under the feet of the driver and passenger - vibrations are maximum here.

2. Tape seams and joints sealant (For example, Terostat 922). This will prevent squeaks and moisture penetration.

3. Paste the second layer - sound insulation (For example, Accent Premium 10 mm). The material should cover the vibration by 10–15 mm at the edges.

4. Replace the factory thermal insulation (if any) and install plastic covers. Check that nothing is rubbing against the metal.

It takes a full cycle 4–6 hours (depending on experience). To speed up the process, you can treat only the front part of the cabin - this will give 60–70% of the effect of complete soundproofing of the floor.

Door treatment: how to get rid of squeaks and wind noise

Doors in Nissan Note - the second most important source of extraneous sounds. It is important to eliminate two problems here: plastic squeaks And wind noise penetration through seals. For complete processing you will need to remove the trim and speakers.

Door materials:

• 🔇 Vibration isolation: Vibroplast Silver (2 mm) - for the metal part.
• 🔊 Noise insulation: Splen 3004 (6 mm) - for the internal cavity.
• 🧴 Anti-creak: Madelin — for plastic panels and fastenings.
• 🚪 Sealant: Bostik MS Polymer - for sealing joints.

Key areas to treat:

1. External door panel — stick vibration insulation onto the metal from the inside, avoiding places where mechanisms are attached (window lifters, locks).

2. Internal cavity — fill the voids with Shumka, especially in the lower part where moisture accumulates.

3. Seals — check their condition. If the rubber becomes dull or cracks, replace it with new ones (part number for Note E11: 80310-4M000).

4. Plastic sheathing - glue all joints and fastenings anti-creaking.

⚠️ Attention: When treating doors, do not seal the drainage holes at the bottom - this will lead to water accumulation and corrosion. Use special plugs with a membrane for them.

How to remove door trim without damage?

1. Unscrew the screws under the decorative plugs (usually 2-3 pieces).

2. Gently pry the clips with a plastic spatula, starting from the bottom corner.

3. Disconnect the speaker and button connectors (remember their location).

4. Remove the trim without using excessive force - the clips are fragile!

Noise insulation of wheel arches: combating road noise

Wheel arches in Nissan Note - the main reason low frequency hum at speed. Factory processing is minimal here, and the open cavities resonate the sound from the tires. For high-quality insulation, you will need to remove the fender liners and clean the surface of dirt.

Recommended materials:

• 🚘 Bimast Bomb (8–10 mm) - for the outer side of the arch.
• 🛡️ Mastic Bomb - for sealing seams and joints.
• 🔧 Accent Premium (6 mm) - for the inside (from the passenger compartment).

Step by step process:

1. Remove the fender liners and thoroughly clean the arches of dirt, rust and oil. Use a wire brush and degreaser.

2. Paste Bimast Bomb on the outer side of the arch, avoiding the suspension mounting points. The material must cover at least 70% of the area.

3. Treat seams and joints Mastic Bomb - this will prevent corrosion and reduce resonance.

4. From the interior side (under the feet), glue Accent Premium for additional noise absorption.

5. Reinstall the wheel arch liners, making sure they do not rub against the wheel when turning.

The effect of processing the arches is immediately noticeable: Tire noise is reduced by 30–40%, and vibrations on the steering wheel practically disappear. This is especially true for owners Nissan Note with winter tires or studded tires.

Sound insulation of roof and pillars: combating wind noise

At speeds above 90 km/h the main source of noise in Nissan Note — aerodynamics. Turbulent air flows over the roof and in the area of ​​the pillars create a whistle and hum. To eliminate the problem, treatment of both external and internal surfaces will be required.

Roof materials:

• ☁️ StP Aero Light (1.5 mm) - for the inside of the roof (does not weigh down the structure).
• 🌪️ Splen 3004 (4 mm) - for pillars and the top of doors.
• 🔗 3M Scotch-Weld - glue for fixing materials on the ceiling.

Processing Features:

1. Remove the ceiling trim (carefully so as not to damage the clips). B Nissan Note it is attached to 4-6 plastic clips and two screws at the sun visors.

2. Clean the roof metal from dust and degrease. Paste StP Aero Light with entry to the racks. Avoid seat belt attachment points and air ducts.

3. For racks use Splen 3004 — it absorbs wind noise better. Glue the materials with an overlap of 10–15 mm.

4. Before assembly, check the operation of all systems: lighting, rain sensors (if equipped) and antenna.

After treating the roof, noise on the highway will decrease by 5–7 dB, and the whistle in the area of the racks will disappear completely. The effect is especially noticeable when the windows are open - air turbulence decreases.

Typical mistakes when soundproofing Nissan Note and how to avoid them

Even with careful preparation, many owners make mistakes that ruin all their efforts. Here are the most common of them:

1. Ignoring surface preparation. Dirt, rust or greasy stains will reduce the adhesion of materials. Always clean and degrease the metal before applying the sticker.

2. Saving on materials. Cheap Shumka loses its properties after 1–2 years, and low-quality vibration insulation peels off. It is better to take proven brands: StP, Accent, Splen.

3. Uneven adhesion. Air bubbles under the vibration reduce its effectiveness by 50%. Use a roller and hair dryer for tight styling.

4. Sealing technological holes. This leads to moisture accumulation and corrosion. For example, drainage holes in doors should be left open.

5. Ignoring anti-creak. Even after noise, plastic panels can creak. Process all joints Madelin or Body 950.

Another common mistake is incorrect work order. For example, they first treat the doors, and then discover that the noise comes through the arches. Start with the loudest areas: floor, arches, engine shield. Only then move on to the doors and roof.

⚠️ Attention: If after soundproofing there is an unpleasant smell in the cabin, most likely you used cheap bitumen material. It may release toxic fumes when heated. In this case, you will have to remove the casing and replace the Shumka with a rubber one.

FAQ: answers to frequently asked questions about sound insulation Nissan Note

How much does complete soundproofing cost? Nissan Note in the service?

The cost depends on the region and level of service. On average:

• 🔧 Budget treatment (floor + doors): 15,000–20,000 ₽.
• 🔧 Full complex (including arches and roof): 30,000–45,000 ₽.
• 🔧 Premium option (with interior analysis and engine shield processing): 50,000–70,000 ₽.

You can save money by purchasing the materials yourself (20–30% cheaper) and agreeing with the service only about the work.

Is it possible to soundproof? Nissan Note with your own hands without experience?

Yes, but start with simple areas: the floor and trunk. The doors and roof will require care to avoid damaging the trim and electrical wiring. Tips for beginners:

• 📹 Film the process - this will help with reassembly.
• 🔧 Buy a set of plastic spatulas for removing clips.
• 📏 Do not cut materials “by eye” - make patterns according to templates.

The first work will take 2-3 times longer than for professionals, but the result is worth it.

What effect does partial sound insulation have (only the floor or doors)?

The effect depends on the treated area:

• 🚗 Gender: reduction of road noise by 30–40%, vibration by 50%. The most noticeable result.
• 🚪 Doors: eliminating squeaks and reducing wind noise by 20–25%. The effect is less than from the floor.
• 🌬️ Roof: Reduces whistling at speed, but has little effect on road noise.

The optimal minimum for Nissan Note — floor + wheel arches. This gives 60–70% of the effect of full treatment.

What materials are best not to use for Nissan Note?

Avoid:

• 🔥 Cheap bitumen vibroplast - melts in the sun and smells.
• 💧 Foam rubber noises - absorb moisture and rot.
• 🧲 Materials without an adhesive layer peel off after a year.
• 🔊 A thin noise (less than 6 mm) does not give a noticeable effect.

For Nissan Note closed-cell rubber or mastic-based materials are ideal.

How much does sound insulation weigh and will it affect the dynamics? Nissan Note?

Weight depends on the configuration:

• 🚗 Full treatment (including arches and roof): +20–30 kg.
• 🚗 Partial (floor + doors): +10–15 kg.

For Nissan Note with engine HR15DE (1.5 l) this is not critical - the difference in acceleration to 100 km/h will be 0.2–0.3 seconds. But comfort will increase significantly.
