Assessment ScoreCard – 31 Day

Assessment Scorecard headlines

All Assessments are based on an ambient background noise of between 30 and 40 dBs i.e. a quiet residential area. Typically the noise from an overflying aircraft is between 50-65 dBs. If your property is located near to a busy road i.e. 70-75 dBs, the noise impact from aircraft will be significantly reduced, whilst the road remains busy.

Note: Overflying aircraft noise typically has a duration of 30-50 seconds, the higher the plane the longer the duration. Whereas the average car, bus or HGV the duration is only a few seconds.
