  1. The What’s and Why’s of Acoustic Damping

    Leave a Comment

    A layered damping system, a vibration-damping sheet, is inserted in between rigid materials. For example, a Green Glue Compound is commonly installed in between drywall layers. The vibration damping materials are what allows for energy to turn into heat. Industrial vibration damping sheets are used for sound and vibration damping on metal panels. These materials can withstand high and low temperatures. The application of these sheets is utilized for a multitude of uses, including buses and railroad cars, ships and boats, generator enclosures, off-highway equipment, hoppers, and more.

    Extensional Damping

    When a damping product is applied to the top of a surface, it is known as an extensional damping system. SoundampE is an example of an extensional damping system. In these systems, energy is turned into heat when the SoundampE is bent. The moment it is impacted, the sound that is against the vibration damping sheet is impacted. This causes another layer to extend and compress which leads to the sound energy changing into heat. Damping products are best for lightweight and are effective in their use. Damping sheets work best for sheet metal and plumbing. The use of these materials for wall and floor assemblies are not useful.

    Damping Resonance

    With partition, the mass allows for resistance to airborne sound waves. To vibrate a heavy partition, a massive amount of noise is needed. However, when airborne noises are applied, it becomes easy for a partition to vibrate. This is commonly known as the resonance point. Partitions with a vast amount of damping sheets are commonly found with wood and drywall. They can have higher resonance problems with no changes occurring in thickness. This issue is lessened with damping sheets that are inserted in between material layers.

    Dissipation

    To determine a product’s usefulness and overall performance, STC results from testing are utilized. The sound that spreads throughout a structure is not able to be tested correctly while in an acoustics lab. If low damping is present, sound vibrations it is more likely for it to travel in between materials at longer distances. Examples of this would be the transferring of sound from walls to floors, et. However, with high damping, sound cannot travel as easily throughout an area and vibration quickly exhausts.

    Damping and Compound Sheets at IES-2000

    As mentioned, industrial SoundamPE vibration sheets are self-adhesive vibration damping pads that are commonly used for sound and vibration damping on metal panels. The odorless and wear-resistant material is intended to prevent the absorption of water. At IES-2000 damping and compound sheets are offered for multiple applications. Damping compounds are also provided that assist in noise reduction purposes. For more information about damping and compound sheets, contact IES-2000 today.

  2. Why is Acoustic Damping the Ideal Choice to Improve Mechanical Sensor Performance?

    Excessive noise can always be a leading factor of distraction or frustration in the workplace. Not only can this be distracting, but excessive noise can also be hazardous when it comes to certain work environments. This is why sound control and noise deadeners are important when it comes to creating a safe, productive workspace. This leads us to the following question: what are the most effective methods to control sound? The short answer, vibration-damping sheets as well as damping compounds. So now you may be asking: what are vibration damping sheets, and why are they the most ideal choice when it comes to improving mechanical sensor performance? What about damping compounds; how are they used, and what are the benefits of using them?

    Damping Compounds and Vibration Damping Sheets

    A damping compound is a sound deadener that consists of filled asphaltic mastic acoustical sheet material and is designed for vibration damping. This specific material used is the most cost-effective as it reduces the echoing vibration of sheet metal panels that burst with noise when cancelled by motor vibration.

    Damping compounds are also ideal since they are non-hazardous and non-toxic. The materials are credited to be durable and sturdy and can be easily applied with a towel as well as a brush or even spray. These can be used on a variety of different surfaces and materials such as metal, wood, plastic, ceramic surfaces, and even glass.

    Vibration damping sheets are self-adhesive damping pads used for vibration damping and sound deadening on metal panels. Vibration damping pads are also used to absorb mechanical energy for overall protection and security. These materials are an ideal choice since the vibration damping material can withstand temperatures from as low as -22 degrees Fahrenheit to as high as 248 degrees Fahrenheit. The vibration damping material is also highly resistant to aging. Vibration damping sheets are also non-hazardous and non-toxic and have a typical lifespan of about six months. These sheets and pads can be applied to buses, boats, trains, and other railroad cars. They are also used for bins, chutes, machine guards, and more.

    What is mechanical damping?

    Mechanical damping is also often referred to as the backing. For mechanical damping to be most effective, the backing should be designed to have high ultrasound retention to prevent noise within itself. When it comes to this, the only disadvantage is that this is solely based on the absorption of energy. Therefore, when working with vibration damping, it is the most effective.
