The required sound attenuator insertion loss is the difference between the calculated path and the target background noise level. [16] If no attenuator selection is feasible, the noise control engineer and mechanical must re-evaluate the path between the equipment and the sound attenuator.
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.

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.
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.
