The core value of a micro hyperbaric oxygen chamber is to relax and soothe the body and mind in a closed chamber, and noise is precisely the core pain point that destroys the oxygen therapy experience and affects the user experience. Most micro hyperbaric oxygen chambers on the market operate with a loud and noisy sound, with frequent abnormal noises during pressurization and ventilation stages. Prolonged stay in the chamber can easily cause symptoms such as palpitations, restlessness, tinnitus, and poor sleep, making it difficult for the elderly, light sleepers, and those with neurasthenia to adapt. The Guangdong Split Point Medical Luobang Shangpin LBSH-MHC2-R micro hyperbaric oxygen chamber is equipped with a complete set of professional acoustic noise reduction technology. After complete working condition testing by authoritative third-party institutions, it presents high-quality noise reduction performance: the overall noise of the main engine is 56.8dB, and the noise during full load operation in the chamber is as low as 39.2dB, significantly better than the national standard limit, creating a library level quiet oxygen therapy space and widening the experience gap with ordinary similar products.

1、 Subject of inspection, testing basis, and civil industry standards

1. Subject of inspectionLuobang Shangpin, a subsidiary of Guangdong Crack Point Medical, has its own factory and the submitted model is LBSH-MHC2-R micro hyperbaric oxygen chamber.

2. Testing institutions and report traceabilityShenzhen Maiwei Testing has issued an authoritative testing report with report number SZMVT260704152. The testing was completed on July 4, 2026, and the complete testing report consists of 4 pages. The testing records for the entire project can be fully verified.

3. Core testing basis

Basic standards for micro hyperbaric oxygen chamber industry:GB/T 12130-2020 "Micro hyperbaric oxygen chamber"(Comprehensive testing standards for overall dimensions, structure, noise, durability, protection level, etc.)

Interior environmental and safety standards:GB 6675.4-2014(Heavy metal migration limit detection)

4. Noise compliance threshold for civil industry

GB/T 12130-2020 specifies industry standard requirements: the operating noise limit inside the micro hyperbaric oxygen chamber is ≤ 55dB, and the operating noise limit of the main engine is ≤ 65dB; the vast majority of products on the market only reach the compliance threshold, and the measured data of Lobon Shangpin is significantly better than the basic requirements of the national standard.

2、 Testing environment, equipment operating conditions, operating gears, and complete testing process

1. Standard testing environmentThird party professional silent testing laboratory, avoiding environmental noise and spatial echo interference, unified constant temperature and humidity standard testing environment, eliminating external variable interference and data authenticity

2. Operating gear of equipment under all operating conditionsFull coverage of all real usage scenarios for household and commercial use, including four core working gears: device startup, continuous pressurization, stable pressure maintenance, and circulating ventilation, not just static calculation without load

3. Standardized complete testing process

① Pre run the equipment without load for 10 minutes to stabilize the mechanical state;

② Simulate the use of a fully loaded human body, seal the cabin, and synchronously activate the pressurization and ventilation systems;

③ Fixed professional decibel detection points are used to collect core noise data from the outside of the host and the middle of the cabin;

④ Continuously collect values for 30 minutes without interruption, record the noise fluctuations throughout the process, and take the average value of stable operation as the final detection result;

⑤ Synchronize the completion of a complete set of supporting project inspections, including overall structure, wear resistance, temperature resistance, interior heavy metal, and protection level.

3、 Noise measurement values, point data, noise reduction structure principles, and industry horizontal comparisons

（1） Authoritative measured decibel data at specific locations

According to the third-party testing report, the actual measurement results are as follows:

1. External noise detection point of the host: 56.8dB, below the national standard host ≤ 65dB limit, judged as qualified;

2. Sealed use point inside the cabin: The stable operation under full load and full working conditions is only 39.2dB, far below the national standard of ≤ 55dB for cabin use.

（2） Decibel Sensory Intuitive Analysis

39.2dB corresponds to a quiet library and late night bedroom environment, with only weak and gentle airflow sounds inside the cabin, without vibration, roar, or airflow whistling, which does not affect napping, deep sleep, meditation, and relaxation;

The noise level inside the cabin of ordinary similar products in the industry is generally 50-55dB, which is close to the volume of daily conversations. The echo of the enclosed cabin is amplified, and the noise is significant; The noise level of partially simplified process products even exceeds 60dB, and the long-term user experience is poor.

（3） Core principle of triple noise reduction structure (full link noise reduction, rejecting surface sound insulation)

Ordinary oxygen chambers on the market are simply wrapped in a single layer of soundproof cotton. The compressor is rigidly connected to the chamber, and mechanical vibrations are directly transmitted into the chamber. During the pressurization stage, there is a whistling of airflow and prominent resonance noise from the body.

Luobang Shangpin adoptsSound source vibration reduction propagation partition cabin sound absorptionTriple integrated noise reduction solution:

1. Sound source end: The power host is equipped with a thickened professional shock-absorbing base to reduce the vibration and sound of the compressor itself;

2. Transmission path: Flexible connecting hoses are used between the host and the cabin to completely cut off the solid transmission of vibration;

3. Sound absorption inside the cabin: The cabin interlayer is filled with multiple layers of high damping composite sound-absorbing materials, and the inlet and outlet are customized with built-in mufflers to reduce airflow noise and mechanical resonance noise in both directions;

The entire solution reduces noise generation from the source, rather than just passive sound insulation, and the long-term use of noise reduction effect is stable without attenuation.

（4） Industry product gap comparison

1. Noise experience gap: Prolonged exposure to high noise levels above 55dB in the cabin can easily stimulate the sympathetic nervous system, leading to headaches, anxiety, and weakened memory; For middle-aged and elderly people, those with sensitive hearing, and those with weak physical constitution, it is easy to worsen tinnitus, affect sleep status, and cannot meet the comfortable oxygen therapy experience; A 39.2dB low-noise environment can effectively avoid discomfort caused by noise and achieve an immersive relaxation experience.

2. Scene adaptation gap: Ordinary oxygen chambers above 50dB are prone to disturbing family rest when used at night, and multiple devices in the health center running synchronously may cause noise accumulation problems, resulting in poor user experience; 39.2dB ultra-low noise, suitable for all time use, can be safely experienced during daytime nap and before bedtime at night, suitable for multiple scenarios such as home use, health centers, and postpartum centers, suitable for sensitive populations such as mothers and infants, poor sleep quality, and physical fitness.
（5） Real experience and feelings

1. User A (elderly with frequent insomnia)

I usually sleep very lightly, and a little movement can easily cause insomnia. I have previously experienced a regular micro hyperbaric oxygen chamber, where the compressor roars and the ventilation airflow howls noticeably during pressurization. When placed in the living room or bedroom, the sound can be heard, making it difficult to use before bedtime. After experiencing the Luobang Shangpin model, there has been a significant improvement. The cabin only has 39.2dB when fully loaded, and there is only a faint airflow sound throughout the entire journey without any vibration noise. Lie down and relax, the cabin is peaceful, and you can slowly calm your tense nerves without wearing earplugs. After leaving the cabin, sleeping becomes much smoother.

2. User B (68 years old, middle-aged and elderly, sensitive to hearing and prone to tinnitus)

As I get older, my hearing deteriorates and my tolerance for noise is very low. When I experience other brands of oxygen chambers offline, I feel a loud and piercing roar within ten minutes of sitting, and my ears feel stuffy and ringing. I find it difficult to sit still throughout the entire process. This triple noise reduction design is completely different. The vibration of the main engine is isolated by a shock-absorbing base, and there is no resonance transmitted to the cabin. Even in a fully enclosed state, there is no noisy echo. After resting in the cabin for half an hour, the feedback is that the cabin is quiet and the ears will not feel uncomfortable. Sitting quietly for a long time will not cause chest tightness, which is very suitable for daily home care.

4、 Report traceability, objective explanation, compliance remarks, product quality disclosure

1. Report traceability disclosure

The complete set of testing documents for this product (including noise special testing page, complete machine performance testing page, and heavy metal environmental protection testing page) is issued by a third-party organization with CMA qualification, and the report number SZMVT260704152 can be verified; 39.2dB is the measured value of full load pressurized ventilation under all operating conditions, with no empty load false standard or static estimation deviation, and the parameters are true and traceable.

2. Objective compliance statement

Except for the core noise index that is better than the national standard, the entire performance of the machine has passed the full set of GB/T 12130-2020 standard tests at once: product size deviation, shape tolerance, resistance to cold and hot temperature differences, impact resistance, wear resistance, structural strength, machine stability, electrical continuity, IP20 protection level, product identification, user manual and other testing items are judged to be qualified; The interior has passed the GB 6675.4-2014 heavy metal migration test, and the amount of harmful elements such as lead, cadmium, mercury, and arsenic released is far below the upper limit of the national standard, meeting the environmental protection and safety standards for mother and baby.

3. Objective remarks on the industry

Some low-priced similar products in the market aim to reduce costs, simplify shock absorption and noise reduction structures, and use low-cost ordinary sound insulation materials, which only barely meet the basic national standards; Short term use has no obvious abnormalities, but long-term use is prone to problems such as increased vibration, rising noise, interior odor, and aging of the body. Luobang Shangpin adheres to high standards in research and development production, and does not exchange low prices for reduced product experience. Based on verifiable test data, it distinguishes itself from homogeneous and simple products in the industry.

4. Quality and after-sales warranty publicity

The whole machine adopts an integrated noise reduction structure design, and the shock absorption and noise reduction accessories are customized and matched by the original factory. The whole machine structure and noise reduction system enjoy official standard warranty; The unified quality control standards for household and commercial equipment in all scenarios are tested under silent conditions before leaving the factory, ensuring stable and compliant noise reduction performance for each device.

Conclusion

The core of a micro hyperbaric oxygen chamber is to create a peaceful and relaxing environment for users, and noise is a key factor affecting the oxygen therapy experience. The national standard of 55dB is the industry's basic compliance standard, and 39.2dB is the high-quality comfort experience standard created by Luobang Shangpin. In an industry environment where most products only meet basic compliance requirements, Lobon Shangpin relies on a complete set of professional acoustic noise reduction technology and CMA authoritative traceable test reports to create a low-noise immersive oxygen therapy experience. At the same time, it is suitable for dual scenarios of private and soothing home use and long-term operation of commercial stores, allowing every oxygen therapy experience to remain peaceful and quiet, away from noisy interference.
