It is the opposite of normal damping (oscillation decreases), so in negative damping to get even bigger oscillation.

What is the dissipation formula for sound and distance?
Scroll down to related links and look at "Damping of Air of High Frequencies (Dissipation)".
Mulitipication of negative numbers?
negative x positive = negative negative x negative = positive negative x negative x negative = negative negative x negative x negative x negative = positive .....
Is a positive plus a negative make a positive or a negative?
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
Is a positive divided by a negative a negative?
yes because a negative X a negative is a positive, thus a positive/a negative=a negative
Is a negative multiplied by a negative equal a negative?
No, a negative multiplied by a negative is a positive, as is of course a positive multiplied by a positive. Only when a negative is multiplied by a positive is the answer negative.
Are negative numbers used in measuring decibels?
Yes, for damping.
What is the different between positive and negative decibel?
Negative decibels mean damping (loss) and positive decibels mean amplification (gain).
How can you decrease the degree of damping?
You can decrease the degree of damping by reducing the amount of friction or resistance in the system. This can be achieved by using lighter weight damping materials, adjusting the damping coefficients, or using a less viscous damping fluid.
What is geometric damping?
Geometric damping is also called radiation damping. It is defined as energy radiation into a surrounding medium. Damping is defined as energy dissipation property of structures and materials that are put through time-variable loading.
What is the definition of viscous damping and viscous damping coefficient especially in Civil Engineering.?

What is damping level?
In the damping level the level view and vertical spindle are crossed together...
Which type of damping occurs in automobile's suspensions?
The two most common types of damping in automobile suspensions are hydraulic damping and gas damping. Hydraulic damping uses fluid to dissipate energy and control vibrations, while gas damping uses gas-filled chambers to absorb and reduce shock. Both types work to provide a smoother and more controlled ride for the vehicle.
Damping ratio of higher order systems?
In higher order systems, the damping ratio is determined by the ratio of the actual damping in the system to the critical damping value corresponding to the highest order term in the system transfer function. The damping ratio influences the system's response to a step input, affecting overshoot and settling time. High damping ratios result in quicker settling times but may lead to more overshoot.
What is a gradual loss of amplitude of an oscillator called?
This is known as damping. Damping refers to the gradual decrease in the amplitude of an oscillator's motion due to the energy dissipation in the system.
What is the formula for Damping frequency?
The formula for damping frequency is Ο_d = Ο_n * sqrt(1 - ΞΆ^2), where Ο_d is the damping frequency, Ο_n is the natural frequency, and ΞΆ is the damping ratio. It represents the rate at which the amplitude of a damped oscillator decreases over time.
What are the different methods of damping used in analog indicating instruments?
Damping torque can be provided by: (a) air friction damping (b) fluid friction damping (c) eddy current damping. In air friction damping, a light piston moves with a very small clearance in air chamber. The piston moves against pressure of air in air chamber. In fluid friction damping, light varies are attached to spindle of moving system. The movement of spindle is suppressed due to fluid friction, Eddy current damping is one of the most efficient method of damping. It is based on the principle that whenever a sheet of conducting but non magnetic material like copper or aluminum moves in magnetic field, eddy currents are induced.
What is the unit of damping co efficient?
The unit of damping coefficient is Ns/m, which represents the force required to bring a unit velocity proportional to the damping coefficient to a stop in a unit distance.
