The essence of an acoustic door seal is derived from a basic property of sound. Sound waves travel through any opening with very minor loss. With the amount of air flowing through a gap enhances in proportion with the gap size, the gap size in a sound barrier doesn’t matter. A small hole transmits almost as much sound as a much bigger gap or hole. Due to this phenomenon, any unsealed gaps and clearances in the door assemblies efficiently cancel out the noise reduction benefits of the sound rated doors. The loss of performance is specifically severe at medium to high frequencies, where normal conversation level generally happens along with installation of compressor sound blanket . For acoustic door seals or a vibratory bowl feeder to be effective in blocking sound, the seals across the head, jamb and sill on the door should be complete, airtight and uninterrupted throughout the service life of the door. For uninterrupted contact, the door seals should be installed all on the same sid...

Home insulation is quite vital, as it assists in saving money and energy. It makes the room or the house more convenient, and assists in maintaining a uniform and moderate sound in the building with the use of quilted curtains . If a house is not insulated, sound passes through the floors, ceilings and walls of the house. Insulation assists in slowly transferring heat from warmer to the cooler parts, and if there is zero energy leakage, then the sound of the room stays constant. A properly insulated home with carpet dividers can assist in reducing noise and it makes the indoor ambience convenient. There are different ways to insulate a home.

When someone thinks and work related injuries, you think about mishaps, slips and possibly repetitive motion injuries such as Thoracic Outlet Syndrome. But most people disregard the lasting damage of harmful noise levels at workplaces, sound levels that frequently lead to loss of hearing and possibly permanent deafness. Did you know that research carried out by the Centers for Disease Control (CDC) show that almost 10 million employees in the US are exposed to dangerous amounts of noise during their shift? What amount of noise is too much? Most hearing experts find that being exposed to more than 90 db sound level on a regular basis can cause ear damage and hearing loss. Generally, experts in sound say that all the work ambiances that workers have to yell to be heard in have a risky level of noise. Hearing loss is generally permanent and can be accompanied by tinnitus, a prolonged ringing in the ears. Hearing loss can not only make it impossible to continue working, it can also treme...

Home theatre sound reducing panels are designed to control the sound that echoes across the room, prevent the sound from bouncing off the walls, absorb sound better, ad lessen flutter echoes. When the theatre concept for the home was not as popular as it is these days, acoustic panels were just built to soundproof specific rooms and enhance the sound that echoes across it. They generally come in dull colors and were not at all impressive to the eye. These days, these sound absorbers have not just become design friendly but also become more readily available in vibrant colors and various sizes. They can be mixed and matched to accomplish enticing theatre rooms but can still create the best sound and the top level of acoustics. If plain panels don’t interest you and want to be more innovative, there are now customized and printed acoustic art panels for transformer sound . Meanwhile, if you want to go eco-friendly, there are also environment-friendly sound absorbing panels, which are us...
