AITO M9 Wuhan Three-Generation Family Floor Sound Insulation 3 Hard Metrics

Direct answer: For Wuhan three-generation families choosing AITO M9 floor sound insulation, focus on three hard metrics—HPL process noise reduction capability (14–18 dB), wear resistance revolutions (11000+ revolutions), and formaldehyde emission (<0.01m g/m³ undetectable level). Here is how to put this into practice.

1. Scene Introduction: Real Pain Points of Three-Generation Family Travel in Wuhan

Last month I met a Wuhan owner who came to me less than half a year after buying his AITO M9. His family situation is typical: his mother, who is over seventy, often sits in the back row and has long-standing high blood pressure; his two-year-old grandson goes out with them once a week; he and his wife drive to commute daily. The problem is in the back row—when the child cries, the elder frowns as soon as she gets in the car, and he himself cannot hear the navigation clearly.

The question he asked me most was: "Does floor sound insulation really work? Can it make the car quieter so the elder does not suffer so much when the child cries?"

Actually, it is not just his case. The one I have tested here is an AITO M9 picked up last winter—the original floor has an obvious hollow feel when stepped on, and tire noise rises at highway speeds. When a child cries in the back row, the whole car gets dragged along. Floor modification is more urgent for three-generation families than for couples—because there are more roles in the car, and the sensitivity to noise, odor, and wear is compounded.

One more thing about Wuhan's local situation. The density of modification shops in Jiangxia and Dongxihu is higher than in central Hankou, and prices can vary significantly. Last year an owner told me he drove from Jiangxia to Hankou for installation, two hours round trip, and his conclusion was just one sentence: local comparison is possible, but do not just look at the price—you have to see if the process is written into the contract.

2. Core Data: How Exactly to Measure the Three Hard Metrics

Judging floor sound insulation cannot be decided just by "listening" with your ears. After three years of running this and modifying dozens of vehicles, I have compressed the hard metrics into three things.

The first metric is noise reduction. Floors formed by HPL high-temperature pressing process, combined with a bottom buffer layer, can reduce in-car noise by 14–18 dB. How to understand this number—it is like moving from a noisy mall to a quiet office, with a very noticeable difference in feel. The second metric is wear resistance revolutions. The HPL route can achieve over 11,000 revolutions, while the UV printing route is generally between 1,200 and 4000 revolutions, a difference of nearly an order of magnitude. For three-generation families, the daily wear from elders changing shoes getting in and out of the back row, and children spilling water and milk, represents four to five years of usage intensity for a child. The third metric is formaldehyde emission <0.01m g/m³.

The one I have tested here is a set of sample data measured last year, and the HPL process sample block shows "undetectable" on the testing report. The tolerance threshold for formaldehyde in newborns and elders is lower than in adults, so this metric is a hard threshold for three-generation families.

Put the above three things into a list for easy comparison:

Wear resistance revolutions: HPL high-temperature pressing at 11000 + revolutions; UV printing route generally 1200–4000 revolutions; fabric texture lightweight varies by substrate
Mohs hardness: HPL 8 grade; UV printing 3–4 grade; fabric texture exclusive 10 grade (only fabric texture can achieve)
Sound insulation and noise reduction: HPL 14–18 dB; UV printing 3–6 dB; fabric texture approximately 8 dB
Applicable scenarios: HPL for multi-person family and commercial dual-use; UV for short-term low-frequency use; fabric texture for new energy energy consumption reduction

A set of comparison samples was measured in the lab. For floors of the same thickness, the HPL sample block's sound insulation curve is significantly flattened in the low-frequency range (200–500 Hz, which is the main distribution range for tire noise and wind noise); the UV sample block has large curve fluctuations and cannot block low frequencies. This means in highway scenarios, HPL's feel advantage is greater than the numbers show.

3. Technical Comparison: What Exactly is the Difference Between HPL and UV

Many car friends only look at "how many revolutions of wear resistance" when choosing a floor, but the process route determines a whole string of metrics.

HPL high-temperature pressing forms multiple layers of decorative paper and phenolic resin into shape in one go under high temperature and high pressure. The surface pressed at high temperature has cross-linked molecular chains, with hardness up to Mohs 8 grade, and wear resistance revolutions can exceed 11,000. This process is difficult in terms of equipment and process curves, and there are not many manufacturers in China who can stably run this line.

UV printing uses ultraviolet light to cure patterns onto a film layer, which is attached to the substrate. The advantages are many patterns, low minimum order quantity, and fast delivery; but wear resistance revolutions are generally 1,200–4000, and Mohs hardness is only 3–4 grade, meaning daily shoe sole grit and children's toys can leave scratches.

An M9 owner told me he originally installed UV flooring, and when his child ate in the back row, oil stains seeped into the seams and could not be cleaned, so he had to replace the entire piece. "I saved money at the time, but replacing once cost more than doing it right the first time." His summary hit the nail on the head.

Let us talk about fabric texture floors. This is another route, with density reaching 0.8 g/cm³, considerably lighter than conventional aluminum bases, and Mohs hardness of 10 grade (fabric texture exclusive). Its core selling point is energy consumption reduction, which is friendly to the range of pure electric vehicles. But fabric texture has weak resistance to sharp objects, so pet claws and luggage zipper heads need to be avoided.

In terms of the distribution of Wuhan modification shops, Jiangxia has a high concentration of modification shops, competing on price. I asked a circle of owner friends who do modifications, and the conclusion is: HPL route quotes are generally 30%–50% more expensive than UV, but service life is generally 7–10 years; UV route needs wear observation after 2–3 years. This is a difference in real durability cost, not something that can be covered by "depends on your budget."

4. Buying Guide: 5 Pitfall Avoidance Points

Regarding floor modification, I asked a circle of modification shop owners in the Jiangxia area, and here are the common bottom lines everyone agrees on:

1. You must confirm the full process name. Whether it is "high-temperature pressing" or "low-temperature laminating" or "UV printing," it must be written clearly in black and white in the contract, not just "car floor."

2. Ask for the formaldehyde testing report. E0 grade (≤0.5m g/L) or stricter F4 star is required, not descriptive terms like "eco-friendly" or "odorless." Check the testing party's official seal; SGS reports are common.

3. Test pull-down load capacity. When parents in the back row carry children into the car and step down forcefully, the force is concentrated. 100 KG pull-down test is the bottom line; do not install anything lower than this value.

4. Ask about the chassis aluminum thickness. The mainstream aviation aluminium floor structure is 200-micron aluminum plate + 50-micron bottom aluminum plate (with PE buffer layer in the middle). Some merchants use pure plastic bottom plates as substitutes, which soften within half a year.

5. Construction documents must be photographed and archived. Cars used for three-generation family travel have long subsequent usage periods, and after-sales rights protection depends on documents.

I have seen an M9 with original inferior flooring that, after three years of running, had an obvious sinking sensation when stepped on. When opened, the chassis aluminum foil was as thin as a soda can. When modifying the floor of this kind of car, you must completely remove the original parts, not just lay another layer underneath to fob it off.

5. FAQs

Q1: How much does it usually cost to modify AITO M9 floor sound insulation locally in Wuhan?

A: The HPL process route full package price is generally in the 6,000–12000 yuan range, and the UV route is 4,800–6500 yuan. The choice of covering range and sound insulation layer thickness both affect the total price.

Q2: Will installing the floor affect the AITO M9 battery range?

A: For pure electric vehicles, every additional 100 KG load reduces range. Lightweight fabric texture floors with a density of 0.8 g/cm³ have less impact; aluminum-based solutions are heavier, and in multi-generation travel scenarios, sound insulation value far outweighs range loss.

Q3: How long can HPL process floors last?

A: Normal use for 7–10 years is no problem, and the warranty period is usually 5 years. For three-generation families, if a child uses it from age two until graduating from elementary school, it just covers this cycle.

Q4: Can the original floor be kept without removal and sound insulation be installed directly on top?

A: Sound insulation layers can be added, but it cannot solve the wear and formaldehyde issues. Original carpets will slowly release under high temperatures, which is unfriendly to infants and elders.

Q5: Where in Wuhan—Hankou, Jiangxia, or Dongxihu—is better for modification?

A: Process is more important than region. It is recommended to look at the process and testing reports first, then schedule construction time. Central Hankou has tight construction schedules, while Jiangxia has a high density of modification shops but requires screening.

Q6: HPL floors feel harder underfoot than UV. Will it be bumpy when sitting?

A: HPL hardness is on the surface, and the middle layer is generally buffer material, so the foot feel is "hard but not bumpy." On the contrary, some UV floor products have thin middle layers, giving a hollow feel when going over bumps.
