Muffler. 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 ...
Overview. According to The New Grove Dictionary of Music and Musicians, a mute is a "device used on a musical instrument to modify its timbre by reducing the intensity of certain partials and amplifying others". [1] More generally, it refers to "any of various devices used to muffle or soften the tone of an instrument". [2]
Original equipment mufflers typically reduces the noise level from the tailpipe by bouncing sound waves off of the back, front, and sides of the muffler. [11] They are designed to meet the maximum allowable noise level required by government regulations. However, some original equipment mufflers are a significant source of backpressure.
The five Korotkoff sounds. There are five Korotkoff sounds: [7] Phase I: The first appearance of faint, repetitive, clear tapping sounds which gradually increase in intensity for at least two consecutive beats is the systolic blood pressure. Phase II: A brief period may follow during which the sounds soften and acquire a swishing quality.
A sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces.
cardiac tamponade. Beck's triad is a collection of three medical signs associated with acute cardiac tamponade, a medical emergency when excessive fluid accumulates in the pericardial sac around the heart and impairs its ability to pump blood. The signs are low arterial blood pressure, distended neck veins, and distant, muffled heart sounds.
Conga. The conga, also known as tumbadora, is a tall, narrow, single-headed drum from Cuba. Congas are staved like barrels and classified into three types: quinto (lead drum, highest), tres dos or tres golpes (middle), and tumba or salidor (lowest). Congas were originally used in Afro-Cuban music genres such as conga (hence their name) and ...
Introduction. Transmission loss (TL) in duct acoustics is defined as the difference between the power incident on a duct acoustic device (muffler) and that transmitted downstream into an anechoic termination. Transmission loss is independent of the source, [1][2] if only plane waves are incident at the inlet of the device. [2]
