1- sound-absorbing tile is mounted on parts of the wall and vault.
2- The vehicle had additional sound-absorbing insulation.
3- One such field of study is the characterization and development of sound-absorbing or damping materials.
4- Newly fallen snow acts as a sound-absorbing material, which minimizes sound over its surface.
5- The only major component of sheet metal not made from aluminum is the Quiet Steel sound-absorbing firewall.
6- The sound-absorbing headliner also reduces wind noise by up to 2 dB in comparison to its predecessor.
7- For example, rugs or other sound-absorbing surfaces make it easier for some children to hear stories or conversation.
8- Many of these techniques rely upon materials science applications of constructing sound baffles or using sound-absorbing liners for interior spaces.
9- In order to reduce noise levels emitted by a source, there are two well-known solutions: passive control, which consists in isolating the source with the help of sound-absorbing materials, and active control, where additional sound sources are used to cancel out the effects of the so-called primary source.
10- Combining the casualness of a sofa with the intimacy of a meeting room, the "Alcove" allows for private conversations within its textile-covered, sound-absorbing walls – without participants having to retreat behind locked doors.
11- Three and a half tonnes of ballast water could be saved and the engines ran quieter because of the sound-absorbing effect of the device.
12- The upgrades include new larger storage bins, multicolored LED lighting, sound-absorbing structures and a modern in-flight entertainment system (IFE) .
13- These include an air inlet containing sound-absorbing materials and exhaust duct cover with a chevron-toothed pattern on the rim for a quieter mixing of exhaust and outside air.
14- Using blankets, panels, and sound-absorbing materials in various configurations, dishwashers can achieve sound damping levels down to 39 decibels or so.
15- On modern military submarines the outer hull is covered with a layer of sound-absorbing rubber, or anechoic plating, to reduce detection.
16- The chair is the furniture equivalent of a Do Not Disturb sign, only shaped like a giant, cartoon phone and clad in a special sound-absorbing upholstery for privacy.
17- Silencer panels installed in the rear-wheel housings , and new sound-absorbing materials added to the trunk's interior side trim further reduce road noise from the tires and wheel housings.
18- sound-absorbing ceiling tiles reduce noise, while strategically positioned sound dispersers, called acoustical soft fits, are suspended from the ceiling to intercept sound as it travels down the hallway.
