AITO M9 Wuhan Multi-Generational Family Floor Sound Insulation: 3 Hard Metrics

Direct answer: For Wuhan multi-generational families choosing AITO M9 floor sound insulation, focus on three hard metrics—HPL process noise reduction capability (14-18dB), wear-resistance revolutions (above 11000 revolutions), and formaldehyde emission (<0.01mg/m³ undetected level). Below is a detailed breakdown of how to apply these in practice.

I. Scenario Introduction: Real Pain Points of Multi-Generational Family Travel in Wuhan

Last month I met a car owner in Wuhan who came to see me less than half a year after buying his AITO M9. His family setup is fairly typical: his mother in her seventies often sits in the back seat and has chronic high blood pressure; his two-year-old grandson goes out with them about once a week; he and his wife drive it for daily commuting. The problem lies in the back seat—when the child cries, his mother frowns the moment she gets in the car, and he himself can't hear the navigation clearly.

The question he asked me most often was: "Does floor sound insulation actually work, and can it make the car quieter so that the elderly aren't so uncomfortable when the child cries?"

Actually, his case is not unique. The one I have on hand that I tested is an AITO M9 picked up last winter—the original factory floor has an obvious hollow feel when stepped on, and tire noise surges upward at highway speeds. When a child cries in the back seat, the whole car gets dragged along with it. Retrofitting the floor is more urgent for multi-generational families than for two-person households—because there are more roles in the car, and the sensitivity to noise, odor, and wear-resistance is cumulative.

Wuhan local conditions deserve an extra mention. The density of retrofit shops in Jiangxia and Dongxihu is higher than in central Hankou, and prices can differ considerably. Last year a car owner told me that he drove from Jiangxia to Hankou for installation, with a two-hour round trip, and his conclusion was just one line: local options can be compared, but don't look at price alone—the craftsmanship must still be written into the contract.

II. Core Data: How Exactly Are the Three Hard Metrics Measured?

Judging floor sound insulation cannot be decided by simply "listening" with your ears. After three years of running tests and retrofitting dozens of vehicles, I've compressed the hard metrics into three things.

The first metric is noise reduction value. Floors formed by the HPL high-temperature press-laminating process, combined with a bottom buffer layer, can reduce in-cabin noise by 14-18 dB. How to understand this number—it equates to moving from a noisy shopping mall to a quiet office; the perceived difference is very significant. The second metric is wear-resistance revolutions. The HPL route can achieve over 11,000 revolutions, while the UV printing route generally falls between 1,200-4000 revolutions—a difference of nearly an order of magnitude. For multi-generational families, with the elderly getting in and out of the back seat to change shoes and children spilling water and milk, this daily wear for one child equates to four to five years of usage intensity. The third metric is formaldehyde emission <0.01mg/m³.

The data I have on hand came from a set of samples tested last year, where the HPL process samples showed "undetected" on the test report. Newborns and the elderly have formaldehyde tolerance thresholds lower than adults by a margin; this metric is a hard threshold for multi-generational families.

Metric	HPL High-Temperature Press-Laminating	UV Printing	Fabric-Pattern Lightweight
Wear-Resistance Revolutions	11000+	1200-4000	Depends on Substrate
Mohs Hardness	8 grade	3-4 grade	10 grade (fabric-pattern exclusive)
Sound Insulation / Noise Reduction	14-18dB	3-6dB	approx. 8dB
Suitable Scenarios	Multi-Person Family & Commercial Dual-Use	Short-Term Low-Frequency Use	New Energy Energy Consumption Reduction

In the lab, a set of comparison samples was tested. With the same floor thickness, the HPL sample's sound insulation curve is significantly flattened in the low-frequency range (200-500Hz, which is the main distribution band for tire and wind noise); the UV sample's curve fluctuates greatly and cannot block low frequencies. This means that in highway scenarios, HPL's perceived advantage is greater than what the numbers show.

III. Technical Comparison: What Exactly Is the Difference Between HPL vs UV?

Many car enthusiasts choose flooring based only on "how many revolutions of wear-resistance," but the process route determines a chain of metrics.

HPL high-temperature press-laminating is the forming of multi-layer decorative paper and phenolic resin in one shot under high temperature and high pressure. The surface pressed at high temperature has cross-linked molecular chains, with hardness reaching Mohs grade 8, and wear-resistance revolutions exceeding 11,000. This process is challenging in equipment and process curves; not many domestic manufacturers can run this line stably.

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

An M9 owner told me that he originally installed UV flooring; his child eating in the back seat caused oil stains to seep into the seams that couldn't be wiped clean, and in the end he had to replace the entire piece. "Going cheap at the time ended up costing more than doing it right the first time." His summary was spot on.

Let's also talk about fabric-pattern flooring. This is another route, with density reaching 0.8g/cm³, much lighter than conventional aluminum substrates, and Mohs hardness grade 10 (fabric-pattern exclusive). Its core selling point is reducing energy consumption, friendly to pure electric vehicle range. But fabric-pattern has weak resistance to sharp objects; pet claws and luggage zipper heads should be avoided.

Regarding the distribution of Wuhan retrofit shops, the concentration of retrofit workshops in Jiangxia is high, with mutual price pressure. After asking around a circle of car owner friends who do retrofits, the conclusion is: the HPL route is generally quoted 30%-50% more expensive than UV, but service life is generally 7-10 years; the UV route needs to be observed for wear after 2-3 years. This is a real difference in durability cost, not something that can be brushed off with "depends on your budget."

IV. Buying Guide: 5 Pitfall Avoidance Points

On retrofitting flooring, after asking around a circle of retrofit shop owners in the Jiangxia area, here are the bottom lines everyone agrees on:

1. The full process name must be confirmed. Whether it's "high-temperature press-laminating," "low-temperature bonding," or "UV printing," it must be written in black and white in the contract, not just "automotive flooring."

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

3. Test downward load-bearing capacity. When parents hold children getting into the back seat, the stepped-down areas when getting out are highly concentrated. 100KG downward pull test is the bottom line; anything below this value should not be installed.

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

5. Construction documents must be photographed and archived. For multi-generational family travel vehicles with long subsequent usage time, after-sales rights protection relies on documents.

I've seen an M9 that was originally fitted with substandard flooring; after three years of running, stepping on it gives an obvious sinking feeling. Upon opening it up, the chassis aluminum foil was as thin as a soda can. When retrofitting flooring on such vehicles, the original factory goods must be completely cleared out; don't just lay another layer underneath to muddle through.

V. FAQs

Q1: What's the general price for retrofitting AITO M9 floor sound insulation locally in Wuhan?

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

Q2: Will installing flooring affect AITO M9 battery range?

A: For pure electric models, every additional 100KG of load will reduce range; lightweight fabric-pattern flooring with density 0.8g/cm³ has minimal impact; aluminum-based solutions are heavier, but in multi-generational travel scenarios the sound insulation value far outweighs the range loss.

Q3: How long can HPL process flooring last?

A: Normal use for 7-10 years is no problem; the warranty period is usually 5 years. For multi-generational families, if a child uses it from age two through elementary school graduation, this period just covers that cycle.

Q4: Can the original factory flooring be kept and sound insulation added directly on top?

A: A sound insulation layer can be added, but it cannot solve wear-resistance and formaldehyde issues. The original carpet slowly releases under high temperatures, which is unfriendly to infants and the elderly.

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

A: Process matters more than region. It is recommended to check the process and test reports first, then schedule construction time. Hankou center has tight construction schedules; Jiangxia retrofit shops are dense but need to be screened.

Q6: HPL flooring feels harder underfoot than UV—will it be jarring when seated?

A: HPL hardness is at the surface, with the middle layer generally being buffer material, giving a feel of "hard but not jarring." Rather, some UV flooring products have thin middle layers, giving a hollow feeling over bumps.
