Many of my friends now feel that their bodies lack exercise, there are no playgrounds and squares around, and it is not safe to run on the street, and they want to buy a treadmill. However, because they live upstairs, they are afraid that the treadmill too loudly interferes with neighbors downstairs. . At the same time, I was worried that I didn't have the perseverance. I might have to go to bed and get a good night's sleep. Home treadmill noise? What about noise? The noise generated by the treadmill mainly has three aspects: The first is the sound produced by the treadmill itself, followed by the friction sound between the human body and the running belt during running, and finally, the sound of the resonance between the body of the treadmill and the ground during running. The first kind of treadmill's own voice, this one need not worry, because in this regard the country has mandatory regulations, which means that the sound generated by the treadmill itself must be controlled within a certain range, so as to allow access to market sales; The size of the two kinds of sound involved more factors, such as weight, treadmill damping, treadmill motors, etc.; and the treadmill noise heard downstairs is mainly caused by the third type of resonance. When the treadmill reaches a certain speed and the vibration reaches a certain frequency, the entire physical system will produce the maximum vibration. In the case of resonance, the sound of the engine and the sound of people stepping on the running boards will be amplified. These sounds will pass through the ground, spread to the walls, and then pass downstairs, making it a harsh noise plaguing the neighbors downstairs. How to solve the home treadmill noise? Treadmill noise formation is not formed by running the treadmill itself. Treadmill motor production standards up to 80 decibels. Completely within the specified non-noise standards. And this kind of voice cannot be transmitted downstairs and can only be heard in your own room. The noise of the treadmill running downstairs is due to the user's very frequent footsteps, and a buzzing sound is formed on the wooden running board. This sound is transmitted through the resonance to the downstairs. “Resonance is the case where a physical system vibrates at its maximum amplitude at a specific frequency. The entire building where the treadmill is located, including the furniture and appliances in the building, is a physical system, and when the treadmill reaches a certain speed When the vibration reaches a certain frequency, the entire physical system will produce the maximum vibration.In the case of resonance, the sound of the engine and the sound of people stepping on the running board will be amplified. These sounds will be transmitted to the wall through the ground and then transmitted. Downstairs, it became a harsh noise that plagued neighbors downstairs." 1, the simplest is to put the treadmill on the balcony, the balcony is far from the living area, if there is noise, the main impact is the balcony downstairs. If placed indoors, it is better to use the treadmill placed against the wall in the center of the house. The resonance during running will be magnified and it will easily affect the downstairs neighbors. 2. In general old communities, due to floor design and age issues, sound insulation between floors is poor. At this time, under the treadmill, a pad with an area greater than the size of the treadmill can be placed on the treadmill to block the noise from transmitting through the ground. 3. When running on a treadmill, it is best to wear soft running shoes. Lubrication of the running belt on a regular basis will increase the noise due to friction between the running belt and running boards and other parts. It is recommended that the running belt be regularly lubricated in accordance with the instructions and frequency of use. 4, choose a treadmill, it is best to buy a large, old brand of machine, the weight of the machine is relatively stable, people do not stand up and down swing. If the treadmill is very light and the ankles of people are going up, the machine will rub and collide with the ground, and the sound of "click" will come out.
With the great efforts of our talented and diligent R&D team, we not only could produce the PLLA/PCL polymers, but also the PLLA/PCL microspheres from 5μm to 30μm. Because of good biocompatibility and biodegradability, they can be used in various areas, such as for plastic surgery implants, dermal fillers and other high-end anti-aging cosmetic products.
