Assessment ScoreCard – 31 Day

Assessment Scorecard headlines

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

Note: Airborne aircraft noise is typically in the range of 45dB - 65dB for heights below 26,000 feet and for a duration of 30-50 seconds. Whereas the average car, bus or HGV the duration is only a few seconds.

Assessment description

Sound equates to an "A" road or a busy "B" road i.e. regular traffic that will be noticeable at peak times which includes evenings and weekends. Location is on a primary flight corridor or flight route or in a flight holding stack area. At times there will be multiple flight occurrences within the same hour, typically between 4-10. Some of the flights will be below 7000 feet.
