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.
Xiangsheng (traditional Chinese: 相聲; simplified Chinese: 相声; pinyin: Xiàngsheng; lit. 'face and voice'), also known as crosstalk or comic dialog, [2] is a traditional performing art in Chinese comedy, and one of the most popular elements in Chinese culture.
There also exist optical attenuators that decrease the signal in a fiber optic cable intentionally. Attenuation of light is also important in physical oceanography . This same effect is an important consideration in weather radar , as raindrops absorb a part of the emitted beam that is more or less significant, depending on the wavelength used.
Built-in variable optical attenuators may be either manually or electrically controlled. A manual device is useful for one-time set up of a system, and is a near-equivalent to a fixed attenuator, and may be referred to as an "adjustable attenuator". In contrast, an electrically controlled attenuator can provide adaptive power optimization.
It is an alternative to Singapore Interbank Offered Rate (SIBOR) which is a measure of the interbank money market rates. [1] As of December 2018, SOR is measured and published periods of overnight, 1 month, 3 month, and 6 month. Like SIBOR, SOR is set by the Association of Banks in Singapore, and is also publicly available. [2]

Attenuator (electronics), an electronic device that reduces the amplitude of an electronic signal. Optical attenuator, an electronic device that reduces the amplitude of an optical signal. Attenuator (genetics), a specific regulatory sequence transcribed into RNA. Impact attenuator, used on highways as a crumple zone in case of a car crash.
In structured cabling, crosstalk refers to electromagnetic interference from one unshielded twisted pair to another twisted pair, normally running in parallel. Signals traveling through adjacent pairs of wire create magnetic fields that interact with each other, inducing interference in the neighboring pair.
