Noise & Vibration

Audio description: The film starts with a shot of a modern washing machine in a clean empty space. The washing machine is on. The voiceover says: A quiet appliance can be an important factor during the product purchase. Audio description: The next scene shows a close up of the washing tumbler with clothes spinning inside. The voiceover says: 3M can provide multiple ways to reduce the noise in an appliance. Audio description: We see water and soap splashing on to the glass window of the washing machine. The next scene shows two 3M Tapes hovering on a blue background. On the left we see a wide brown 3M Damping Foil 2552 on the right side we see silver 3M Vibration Damping Tape 435. The names of the products are display as texts above the tapes. The voiceover explains: 3M Damping Tape can help reduce vibrations in the appliance components. Audio description: We cut to a quick shot of the washing machine transmission wheel spinning quickly and shaking. After that, on a blue screen, we see another two 3M products with names written above them. On the left side, a white sheet of 3M Thinsulate Acoustic Insuation TAI3047 is visible. Next to it, on the right side, we see a grey sheet of 3M Thinsulate Acoustic Insulation AU4002. The voiceover says: To improve noise absorbtion use 3M Thinsulate, a non woven material that is lightweight and hydrophobic, to help resist mold and mildew. Audio description: Back to the story, the next scene shows the designer's hand, working on the digital blueprint of the appliance project. The voiceover explains: When designing an appliance, it can be difficult to predict the noises that will be produced, especially when they are amplified by other elements or resonate with other sounds. Audio description: We cut to the animation of interlapping audio wave forms that interact with each creating peaks of noise. The next scene shows a demo animation depicting a wave form of noise created when a metal ball hits the bear sheet of steel. The level of noise grows to a dangerous level. The voiceover says: 3M Damping Tape efficciently dissipates the resonate energy and helps reduce vibration and different frequencies of noise. Audio description: In the next scene, the same metal ball hits the sheet of steel with a 3M Thinsulate Tape attached to it. The noise and vibration produced is visibly smaller than the one before. Now the camera is inside the washing machine factory. A line of washing machines metal bodies is transported on the assembly line. Voiceover says: You may also be able to optimize the amount of materials used to achieve your noise reduction goals. Audio description: We cut to an animation of the washing machine metal body. Inside of it we see the application of the 3M Damping foil and Thinsulate material. Voiceover explains: With 3M Damping Tape, you can achieve great results without the need of redesigning the product. Utilizing 3M Thinsulate may further improve noise absorbtion, to reduce the overall noise level of your appliance. Audio description: The film concludes with a white board showing the 3M logo and the slogan Science Applied to Life. The Voiceover reads: 3M Science Applied to Life.
