Impact attenuator Impact attenuator. A Truck-Mounted Attenuator (TMA) in Auckland. An impact attenuator, also known as a Truck Mounted Attenuator (TMA), crash cushion, crash attenuator, or cowboy cushion, is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision. Impact attenuators are designed to absorb the colliding vehicle's kinetic energy.

Attenuators Chapter 1 - Amplifiers and Active Devices. Attenuators are passive devices. It is convenient to discuss them along with decibels. Attenuators weaken or attenuate the high level output of a signal generator, for example, to provide a lower level signal for something like the antenna input of a sensitive radio receiver. (Figure below) The attenuator could be built into the signal generator, or be a stand-alone device.

Environmental impact of agriculture There are two types of indicators of environmental impact: means-based, which is based on the farmer's production methods, and effect-based, which is the impact that farming methods have on the farming system or on emissions to the environment.

Occupational Safety and Health Administration The OSHA limit for impulsive or impact noise is also 140 dB peak sound pressure level. This limit is independent of the duration of the noise impulse. There is no OSHA limit for number of exposures to impulsive or impact noise. Impulsive or impact noise must be integrated into the measurement of continuous noise exposure, however. The UL provision for peak acoustic pressure also states: Peak hold is defined as an acoustic response having a duration less than 50 microseconds.

Attenuation Attenuation in ultrasound is the reduction in amplitude of the ultrasound beam as a function of distance through the imaging medium. Accounting for attenuation effects in ultrasound is important because a reduced signal amplitude can affect the quality of the image produced.n engineering, attenuation is usually measured in units of decibels per unit length of medium (dB/cm, dB/km, etc.) and is represented by the attenuation coefficient of the medium in question.

Disparate Impact A theory of liability that prohibits an employer from using a facially neutral employment practice that has an unjustified adverse impact on members of a protected class. A facially neutral employment practice is one that does not appear to be discriminatory on its face; rather it is one that is discriminatory in its application or effect.

RF Attenuator Basics & Tutorial FET RF attenuators: FET attenuators are normally used in attenuator designs where a continuously variable level is required. Like a PIN diode attenuator, FET attenuators use an analogue control voltage to control the level of attenuation. These are only broad categories for RF attenuators - they can be categories in a variety of ways according to the application and the type of attenuator technology that is used.

- Impact sound (or impact noise) is a form of structure-borne sound that occurs when an object impacts on another, resulting in the generation and transmission of sound. The structural vibration caused by the impact results in sound being radiated from an adjacent vibrating surface.
