VIBRATION ASSESSMENT (BS 6472)


BS 6472:1992 – Guide to evaluation of human exposure to vibration in buildings (1 Hz to 80 Hz)

This British Standard provides an overall guide to those who are exposed to building vibration with the frequency of 1 Hz up to 80 Hz.

BS 6472 explains the application of weighting curves, blast-induced vibration and the current methods of assessing continuous, intermittent and impulsive vibration; it also offers guidance on vibration conditions.

Perhaps the most commonly used for environmental vibration assessments, this Standard is commonly used to assess the vibration caused by railways.

Sound Planning provides vibration assessments based on this standard. We provide consulting support throughout the UK to ensure that you conform to government regulations with regards to the environmental impacts of vibrations.

Scope of BS 6472-1:2008

  • Application of methods of measuring and evaluating vibration
  • Guidance when it comes to predicting the human response to vibration with a frequency range of 0.5 Hz to 80 Hz
  • Advice on measurement methods to be employed
  • Methods of assessing continuous, intermittent and impulsive vibration
  • An acoustic engineer can determine the VDV from frequency-weighted vibration measurements
  • Guidance on how people inside buildings respond to building vibration

Vibration Sources other than Blasting:

External sources

  • Forging
  • Presswork
  • Construction work
  • Demolition work

Internal sources

  • Lifts
  • Air-conditioning or ventilation plant
  • Heavy office machinery
  • Appliances like vacuum cleaners or washing machines
  • Door slamming

Human induced vibration source

  • Walking at a steady pacing rate
  • Running
  • Jumping up and down
  • Dancing with music

Scope of BS 6472-2:2008

  • The problems associated with periodic blasting within the range of an occupied building
  • Particular problems associated with periodic blasting within range of occupied buildings
  • Guidance on human exposure to blast-induced vibration in buildings
  • Other forms of vibration that are caused by blasting, including when explosives are utilised in civil engineering works and in demolition activity

Examples of Blast-Induced Vibration:

  • Blasting associated with mineral extraction
  • Explosives that are utilised in civil engineering works or in demolition activities

Different Types of Vibration that can be assessed

  • Continuous vibration
  • Impulsive vibration
  • Intermittent vibration
