Noise insulation, vibration reduction, architectural acoustics

Airports and Railway Stations

In the design, construction, and renovation of the railway station and airport buildings, a great attention should be paid to the issues of sound and vibration insulation as well as to creating the required acoustic comfort in the premises. In addition to a favorable acoustic environment during leisure and waiting for flights or trains, passengers must hear all the speaker's announcements clearly and legibly.

Key numbers

> 110 dBA

the maximum sound level when starting engines of a wide-body aircraft, as measured at a distance of 20 m from the nearest aircraft engine

60 dBA

the allowable (equivalent) sound level in the check-in and waiting areas for airport passengers

1-1,5 sec.

the allowable reverberation time at mid frequencies for passenger check-in and waiting areas depending on the air volume of the room

Issues of Sound and Vibration Insulation and Acoustics in the Premises of Railway Stations and Airports:

  • Sound and vibration insulation of engineering systems: reducing the noise from ventilation and air conditioning systems as well as other adjacent service premises (vibration insulation of refrigerators, noise insulation of chillers, etc.). In this case, the objects of protection are waiting rooms as well as shopping, utility, and administrative premises of a railway station or an airport.
    As an example, we can cite an interesting case of building the new terminal of an international airport in one of the capital cities. The air conditioning chiller generated so much vibration that, in a fairly spacious room of a duty-free shop located under it, the staff was unable to work. It is important that, when designing, designers did not care enough about vibration insulation: first, the shopping room was huge; second, the unit itself was located on the roof; and, thirdly, the noise requirements for stores are much less strict than for residential premises. As a result, after starting the air conditioning system, it became clear that a more serious system of vibration insulation should be provided for this unit. However, reconfiguring an already commissioned unit is always more complicated and costly.
  • Vibration insulation of rail tracks (in case of a railway station); vibration insulation of foundations.
  • Additional soundproofing of administrative offices and business halls.
  • Creating a comfortable acoustic environment in the premises of waiting rooms and other recreational areas of a transport hub.
