A story about positive side effects of vibrations.
For doubling the capacity, an additional 4 MW reciprocating compressor was installed in an underground gas storage. Afterwards , several members of the staff in the administration building complained about vibrating desks, computer screens etc.
Furthermore, very disagreeable vibrations occurred in the private home of a neighbor, 160 m away from the compressor. F.ex. the central-heating boiler was making an annoying noise that was strongly inconvenient for sleep during the night.
The operator confirmed that in this residence “flowers were dancing in the window and the clothes horse was trembling like a guitar”.
