- Mechanical vibrations that fall in the frequency range that we are capable of hearing are called sound, or sound waves.
- Mechanical vibration is a form of oscillating energy—comprised of forces of specific frequencies that are repeated in a cyclical fashion.
- When this oscillating energy impacts a body (of any kind), it is transferred at the point of impact, causing the back-and-forth or up-and-down motion known as vibration.
- Due to the fact that waves of energy cause vibration, it possesses an amplitude (wave strength) as well as a frequency (number of oscillations of the wave per second). Both of these characteristics must be controlled.
- High pressure mechanical vibration results when the vibration energy has a large amplitude (high strength). As a result, each vibratory impact delivers a high level force. When considering sound vibrations—this translates to a higher level (louder) sound.
- It is also important to consider frequency. This is due to the fact that differing frequencies interact with substances differently. All materials and systems have a natural, or resonance frequency. When the frequency of the vibration impacting the system corresponds to its resonance frequency, that system will begin to resonate. This refers to the situation in which the waves of vibratory energy begin to build on one another. In this way, the amplitude of the vibration is continually increased. Consequently, a vibration of lower amplitude can increase in strength by simply feeding on the lower level of energy being supplied. With respect to sound vibrations, resonance can result in dangerously loud sounds at potentially damaging frequencies.
Mechanical sound vibrations–problems and solutions
- Undesirable mechanical sound vibration in known as noise.
- In the workplace, pneumatic tools, heavy machinery, and industrial equipment can be sources of high level noise. This noise can lead to hearing loss, with certain frequencies being more damaging than others.
- Outside of the workplace, noise control applications include music recording studios and products, such as speakers and DVD/CD players.
- The need exists to address unwanted sound. What’s the best way to stop mechanical sound vibrations? Sorbothane®–it is the most effective product available for damping mechanical sound vibration.
What is Sorbothane®, and how does it address mechanical sound vibrations?
- Sorbothane®, visco-elastic polymeric substance, shows attributes specific to liquids as well as those specific to solids.
- When Sorbothane® is experiencing a load (mechanical sound vibration), it flows as a liquid.
- It returns to its original shape once the impacting force is removed—emulating an elastic solid.
- The absorbed mechanical sound vibration energy is safely dispersed by Sorbothane®—outward from the impact source.
- What’s the best way to stop mechanical sound vibrations? Employ Sorbothane®—the most efficient vibration damper available.
