I said "like a [machine from a particular manufacturer]". There are literally dozens of different manufacturers:: Power Plate, LifePro, Bulefin Fitnes, Confidence Fitness, Sunny Health and Fitness, Vibra Tec, Hurtle, Zeny, Merach, Vibrogym, etc. One line interesting to me is Vibra Pro Fitness, because some of their machines generate torsional vibrations -- but that's just me. Power Plate is but one of many manufacturers.
How can any health club or consumer machine with an oscillating motor in that frequency range be quiet? There are plenty of YT videos showing people on a wide variety of Vibration Plate Exercise Machines -- like https://www.youtube.com/watch?v=VCycu4vgFG0&t=705s . That machine is clearly intended for home use; oppressive noise would not work for condo/apartment users.Their propaganda says "not loud" but if it shakes you at 50Hz how could it not be? Five minutes of Google has turned up only infomercial material. I'll look a bit further.
One video noted low-frequency noise with a home machine. The machine was fine; the problem was the power cord vibrating on a hardwood floor. The fix was easy peasy. If noise at home were a categorical problem for Vibrating Plate exercise machines, the YouTubers would be all over it. Ditto for problems with a vibe machine at a health club. @Sakly's machines at his club sound badly broken: a distraction and possibly a hazard to users. Please report 'em to club management immediately.Q: How can a vibration plate exercise machine oscillating at 50hz be quiet?
A: Making a vibration plate exercise machine operating at 50 Hz quiet requires careful attention to its design and engineering. Here are the primary strategies:
1. Damping and Isolation
• Rubber Feet or Shock Absorbers: Placing high-quality rubber feet or shock absorbers under the machine reduces vibration transmission to the floor, which can amplify noise.
• Internal Damping Materials: Using sound-absorbing materials (e.g., foam, rubber, or silicone) inside the machine’s housing helps dampen vibrations within the structure.
2. Precision Engineering
• Balanced Components: Ensuring that all moving parts are precisely balanced minimizes unnecessary vibrations that can cause noise.
• High-Quality Bearings: Using high-quality, low-friction bearings reduces mechanical noise from the oscillating components.
3. Structural Design
• Rigid Frame: A sturdy frame resists flexing and reduces noise caused by vibration of the structure itself.
• Compact Motors: Using smaller, well-encased motors with efficient designs can significantly reduce motor noise.
4. Acoustic Insulation
• Enclosed Housing: Encasing the motor and mechanical components in soundproofed housing reduces the noise that escapes.
• Sound Barriers: Adding barriers or covers made from sound-dampening materials further minimizes emitted noise.
5. Advanced Motor Technology
• Brushless Motors: Using brushless DC motors or other quiet motor technologies can reduce the hum and buzz typical of older or less efficient motor designs.
• Variable Frequency Drives (VFD): These ensure smoother operation by avoiding abrupt changes in speed or torque that generate noise.
6. Frequency Tuning
• Avoid Resonant Frequencies: Designing the machine to operate at a frequency that does not align with the natural resonant frequency of its components or surroundings reduces noise amplification.
7. User Placement Considerations
• Surface Compatibility: Placing the machine on a carpeted floor or a dedicated anti-vibration mat prevents noise amplification through hard flooring.
• Proper Assembly: Ensuring all parts are tightly secured prevents rattling or clicking noises.
8. Maintenance
• Lubrication: Keeping bearings and other moving parts well-lubricated reduces friction noise.
• Tightened Components: Periodic checks for loose screws or bolts can prevent noise from mechanical looseness.
Implementing a combination of these strategies results in a quieter vibration plate machine without sacrificing performance.
Won't the handles on the PowerPlate get in the way when you ski? I've used one a few times quite a long time ago, but I've never known anyone combining them so I can't help with an answer.floatingbones wrote: ↑December 29th, 2024, 10:42 pmHas anyone experimented with standing on a vibration plate machine -- like the PowerPlate MOVE -- while working out on the SkiErg?
The PowerPlate MOVE doesn't come with a stability bar. It's an option. AFAICT, about half of the vibration plate exercise machines come with a stability bar.Won't the handles on the PowerPlate get in the way when you ski?

Nobody claimed that it does?steveharvey wrote: ↑January 3rd, 2025, 10:42 amHow can combining SkiErg with a PowerPlate machine enhance overall strength and endurance in athletes?
What studies are you citing for your "are both not getting great results in gaining strength" conclusion? What studies did you find showing "no results" for that kind of training? Equivocating the lack of published papers with a negative result is a logical fallacy. If you find no papers, all you can really say is, "We don't know. Nobody has studied that." Dismissing the question in the lack of published papers is pseudoskepticism -- false skepticism.
