Plan the work
Carry the estimate into the job plan.
The useful result is not just the number. It should support owners, programme assumptions and delivery readiness.

Estimate To Evidence
Make the result useful beyond the screen.
A calculator result is most useful when it feeds the job plan, material checks and team briefing that follow the estimate.
Measure the work
Use the estimate as a planning input for scope, labour, equipment and site readiness.
Plan materials
Turn quantities into stock checks, purchasing notes and job-linked material records.
Brief delivery
Give teams the assumptions, limits and checks behind the number before work starts.
Explanation
What this calculates
The calculation normalises the measured or estimated level to an 8-hour working day.
Formula
LEP,d = noise level + 10 x log10(hours / 8)
Inputs are validated on screen and converted where unit options are available.
Worked Example
Example result
90 dB(A) for 2 hours is approximately 84 dB(A) LEP,d.

Related FAQs
What is trigger time?
Trigger time is the time the tool is actually vibrating in the worker's hands, not the whole task duration.
From HAVS Calculator
Should I use declared tool values?
Manufacturer data can be a start, but measured site data is better for risk assessment.
From HAVS Calculator
Is this an official manual handling assessment?
No. It helps triage tasks before a competent risk assessment and site-specific controls.
From Manual Handling Calculator
What should a high score trigger?
Review mechanical aids, team lifting, route changes, reduced load weight, handling frequency and training.
From Manual Handling Calculator
FAQ
Calculator questions.
Does this replace noise monitoring?
No. Use competent monitoring and legal guidance for exposure assessment and controls.
What if there are multiple tools?
Assess each exposure and combine them with a suitable occupational noise method.
