Attenuation-to-crosstalk ratio (ACR) is a parameter that is measured when testing a communication link, which represents the overall performance of the cable. [1] AcR is a mathematical formula that calculates the ratio of attenuation to near-end crosstalk for each combination of cable pairs. [ 2 ]
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.
The signal-to-crosstalk ratio at a specified point in a circuit is the ratio of the power of the wanted signal to the power of the unwanted signal from another channel.. The signals are adjusted in each channel so that they are of equal power at the zero transmission level point in their respective channels.

In electronics, crosstalk is a phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel. Crosstalk is usually caused by undesired capacitive , inductive , or conductive coupling from one circuit or channel to another.
The Singapore dollar (sign: S$; code: SGD) is the official currency of the Republic of Singapore. It is divided into 100 cents (Malay: sen, Chinese: 分; pinyin: fēn, Tamil: காசு, romanized: kācu). It is normally abbreviated with the dollar sign $, or S$ to distinguish it from other dollar-denominated currencies.
