Wave types and propagation; near vs far field.
Near field and far field behave differently. Know which receptor you are protecting.
Write the neighbour limit before the first hit.
Produce an artefact before you tick: a written note, a marked drawing, a cited figure, a filed hold. Watching is learning. The tick means applied.
Study notes. Not a certificate. Not legal advice. We never design the charge, spacing, or the cut. Follow the law and the named people where you work.
Before you tick
- Receptor named.
- Limit written.
- Instrument range known.
Write the neighbour limit before the first hit.
