attenuation vs damping

Both 'attenuation' and 'damping' are correct terms, but they are used in different contexts. 'Attenuation' is commonly used in the context of reducing the intensity of something, such as a signal or sound. 'Damping' is often used in the context of reducing the amplitude of oscillations or vibrations.

attenuation

The term 'attenuation' is correct and commonly used in the context of reducing the intensity of something, such as a signal or sound.

Use 'attenuation' when referring to the reduction in the intensity of something, such as a signal, sound, or wave.

Examples:

  • The attenuation of the sound waves made it difficult to hear the speaker.
  • The attenuation of the radio signal caused interference with the transmission.
  • Actual attenuation of hopped wort - determined by a recommended method.
  • It may simply be a pattern of attenuation.
  • Other methods, such as the beta ray attenuation method and the tapered element oscillating microbalance (TEOM), are currently tested for equivalence with the gravimetric method by CEN WG15.
  • ADAM, beta ray attenuation, sequential, from OPSIS, Sweden,
  • Likely due to injury, given the attenuation of her collateral ligaments.
  • The requirements are expressed as attenuation relative to the maximum carrier power, combined with a fixed upper limit.
  • Adjust the attenuation setting to 70 decibels.
  • The determination of lateral attenuation for finite segments differs markedly for Lmax and LE metrics.
  • This document specifies a method for calculating the attenuation of noise during its outdoor propagation.
  • This loss of acoustic energy when the ray undergoes a reflection is called attenuation through retrodiffraction.
  • The calculation is identical to that of the attenuation by a barrier in the clear area.
  • Γ() Lateral attenuation distance factor
  • The length of each segment and number is strongly influenced by lateral attenuation.
  • The fullness of flavour is mainly due to the presence of unfermented residual extract, characterised by a difference between apparent and real attenuation.
  • Difference between apparent and actual attenuation: 1,0-9,0 (% rel.)
  • (j) the availability of hearing protectors with adequate attenuation characteristics.
  • Instrument sensitivity: from 4 to 16 times the minimum attenuation;
  • Lateral attenuation is a reflection effect, due to interference between directly radiated sound and that which reflects from the surface.
  • Until these are developed, the following methodology, described in AIR-5662, is recommended for calculating lateral attenuation.
  • Variation of lateral attenuation Λ(β,) with elevation angle and distance

Alternatives:

  • reduction
  • weakening
  • diminution
  • decrease
  • loss

damping

The term 'damping' is correct and commonly used in the context of reducing the amplitude of oscillations or vibrations.

Use 'damping' when referring to the reduction of the amplitude of oscillations or vibrations, typically in mechanical systems.

Examples:

  • The damping of the vibrations in the car suspension system improved the ride comfort.
  • The damping of the oscillations in the pendulum slowed down its movement.
  • And the stabilizer gears on the magnetic damping rings.
  • Under no circumstances may the damping constant exceed 5 s.
  • damping or flotation fluids with a purity exceeding 99,8 %, containing less than 25 particles of 200 μm or larger in size per 100 ml and made from at least 85 % of any of the following compounds or materials:
  • damping or flotation fluids with a purity exceeding 99,8 %, containing less than 25 particles of 200 μm or larger in size per 100 ml and made from at least 85 % of any of the following:
  • Assessment and verification: a declaration of the VOC content in alcohols, washing agents, inks, damping solutions or other corresponding chemical products shall be provided by the chemical supplier.
  • Consumables include products such as printing inks and dyes, toners, overprinting varnishes, varnishes, adhesives, washing agents and damping solutions.
  • Frequency and damping of the oscillation of the sprung mass: ...
  • Especially designed or prepared bearing assemblies consisting of an annular magnet suspended within a housing containing a damping medium.
  • Frequency and damping of the oscillation of the sprung mass:
  • The inertial damping fields are barely operational and the warp drive containment field's on the verge of collapse.
  • or with damping of the return movement.
  • the topography of the facility site, including damping features;
  • with damping of the return movement;
  • The damping constant (63 % of the limit value) shall not exceed 0,4 s.
  • The rate-of-turn signal shall be received without additional damping beyond the limits referred to in Article 4.02 (1).
  • dynamic track features (horizontal and vertical track stiffness and track damping),
  • The damping ratio as a fraction of critical is >NUM>C >DEN>Co.
  • NUMK DENM - NUMC² DEN4M² The damping is critical when C = Cº,
  • The damping ratio Dr of the suspension with all hydraulic dampers removed or incapacitated must be not more than 50 % of Dm.
  • The first natural frequency of the impactor shall be over 5000 Hz and it is recommended to use damped accelerometers with a damping ratio of approximately 0,7.';

  • absorption
  • attenuation
  • reduction
  • mitigation
  • suppression
