2. Glasspack - Wikipedia

   en.wikipedia.org/wiki/Glasspack

   This lower flow but slightly quieter design approach is commonly used in glasspack mufflers. Some modern muffler designs are similar in principle to the glasspack, but use more sophisticated sound-absorbing materials such as stainless steel mesh, and more advanced acoustic engineering, reducing noise while retaining the power-preserving ...

   Silencer (silver) and exhaust pipe on a Ducati motorcycle A silencer cut open to show the insulation, chambers and piping inside the shell. A muffler (North American and Australian English) [1] or silencer (British English) is a device for reducing the noise emitted by the exhaust of an internal combustion engine—especially a noise-deadening device forming part of the exhaust system of an ...

4. Sound attenuator - Wikipedia

   en.wikipedia.org/wiki/Sound_attenuator

   The dynamic insertion loss of a sound attenuator is the amount of attenuation, in decibels, provided by the silencer under flow conditions. While flow conditions in typical low velocity duct systems rarely exceed 2000–3000 ft/min, sound attenuators for steam vents must withstand airflow velocities in the 15,000-20,000 ft/min. range.

5. AMC Ambassador - Wikipedia

   en.wikipedia.org/wiki/AMC_Ambassador

   This design was offered by only a few cars at that time. The 1962 models were equipped with "Walker" (brand) flow-through mufflers and a ceramic-coated exhaust system. Dealer-installed options included rear fender skirts and a tow hitch. [18] In 1962, George Romney was elected as the new governor of Michigan, and in February, Roy Abernethy ...

7. Silencer (firearms) - Wikipedia

   en.wikipedia.org/wiki/Silencer_(firearms)

   The muffler for internal combustion engines was developed in parallel with the firearm silencer by Maxim in the early 20th century, using many of the same techniques to provide quieter-running engines, and in many English-speaking countries automobile mufflers are called silencers. [10]
