A novel impulse damper for reducing extreme vibrational events, in particular, in tall, narrow structures such as wind turbines. The impulse damper, according to the invention, operates on the impact-damping principle and is particularly suitable for damping the second natural frequency of the installation, preferably of the tower of a wind turbine.

Described is a system for transmitting a flexural wave acting on one structure to another structure. In one example, a system includes a first structure having a first property and a first end and a second structure having a second property and a second end connected to the first end of the first structure. The first property is different from the second property and may be related to the material and/or geometric properties of the first and second structures. A mechanical resonator is connected to the first structure at a distance from the first end of about a quarter-wavelength of the frequency of a flexural wave acting on the first structure. The mechanical resonator matches a first mechanical impedance of the first structure to a second mechanical impedance of the second structure to allow high transmission of the flexural wave acting on the first structure to the second structure.
