  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. A Guide to Choosing the Right Sound Barrier

    A cost-effective and efficient solution to reduce noises is through a sound barrier blanket. These quilted fiberglass panel solutions are flexible in their usage and are increasingly popular amongst many construction companies. While there is no one solution for every circumstance, there are different types of sound-blocking blankets. Some tend to produce better results than others.

    Defining Outdoor Sound Blankets

    Sound blankets that are utilized outdoors are weather resistant and built to block out noise. The sound panels are used to decrease the sound of equipment and construction equipment. Construction sound blankets are the perfect way to follow through with noise ordinances. Outdoor sound blankets are durable and highly effective. The panels can easily withstand high-intensity wind, temperature variations, and even high UV exposure. The flexible design of the panels allows for a highly supportive structure and frames. Outdoor blankets can either be a temporary or long-term solution.

    What to Search For

    When determining the best outdoor sound blanket fit, there are a few items to check off your list. These items include noise reduction coefficient rating and sound transmission class. Other requirements to look into are temperature range and weather resistance.

    1. Noise Reduction Coefficient

    When it comes to shopping around for sound blankets, there are a few requirements to be aware of. Knowing the noise reduction coefficient rating can allow you to determine how it will operate outdoors. The thicker the blanket and the higher the rating, the better it will be.

    2. Sound Transmission Class

    Along with the noise reduction coefficient factor, it is essential to note the sound transmission class rating. This reading measures the amount of noise that can be reduced within a product. It measures transmission loss and the amount of sound to transfer through a barrier. Sound frequency is read through Hertz measurements. The higher the sound transmission class rating the better it will be.

    3. Temperature and Resistance

    While picking an outdoor blanket, you will of course want to ensure that it comes with weather durability. Since these blankets will be outside during different weather conditions, it is essential to know they can withstand the harshest conditions. From high heat to low temperatures, is the blanket weather resistant? Since these blankets are reusable, they are also a cost-effective solution.

    Choosing IES-2000

    If you are in search of a quilted fiberglass absorber, look no further than IES-2000. At IES-2000, sound absorption blankets drastically reduce the reflection of sound waves. The thickness allows for noise to not completely transfer to the other side. IES-2000 offers high-quality fiberglass sound insulation solutions. Appearing in different thicknesses and appearances, get what you need when choosing IES-2000. For more information, contact IES-2000 today.
