Who Owns the Risk Register - and When Noise Needs an Acoustic Consultant
Every Australian workplace has risks. Not every workplace has a risk register that anyone trusts. The difference is ownership: named people, living evidence, and a clear path from “hazard noted” to “control verified.”
Under WHS law, a PCBU must manage risks so far as reasonably practicable. A register is one practical way to show that work is happening—if it is kept current. This article is general information, not legal advice.
What a risk register is for
A useful register is not a dump of every imaginable hazard. It is a prioritised view of what could harm people, how likely and how severe, what controls exist, who owns them, and when they will be reviewed. When those fields go stale, the register becomes wallpaper for the next audit scramble.
That is why risk register software helps once spreadsheets and shared folders stop scaling. Good tools make owners visible, attach evidence to rows, surface overdue reviews, and keep noise, dust, and plant risks from disappearing into email threads. Software does not replace judgement. It makes judgement auditable.
When noise outgrows a generic row
Noise is a common row that becomes too thin. “Hearing PPE required in Workshop B” might be true and still useless. It does not say which plant dominates, whether engineering controls were considered, how exposure varies by shift, or whether neighbours and environmental limits also apply.
Occupational noise and environmental noise are related but not identical briefs. Worker exposure, community amenity, planning conditions, and complaint response can all sit under “noise” and still need different methods. A thin register row hides that complexity until a complaint or a claim forces the issue.
When to bring in an acoustic consultant
An acoustic consultant helps when the question moves from “we know it’s loud” to “we need defensible measurement, modelling, or advice.” Typical triggers include new plant or layout changes, neighbour complaints, planning or licence conditions, verifying whether controls reduced levels, and designing quieter alternatives before capital spend.
Consultants do not replace the register owner. They feed the register with numbers and recommendations the PCBU can action—enclosures, barriers, maintenance, scheduling, or PPE for residual risk. The value appears when recommendations become tracked actions with dates, not when the report sits unread.
Ownership that keeps experts useful
- Name a risk owner for noise who can close actions—not only file reports.
- Separate worker exposure from environmental amenity in the register when both apply.
- Attach reports to the risk row, not a random shared-drive folder.
- Review after change — new compressors, overtime patterns, and open doors change the story.
- Escalate method, not panic — if the row is thin, buy competence, not another generic policy.
Platforms such as Lahebo and acoustic specialists such as Noise Assessment (Anitech portfolio) typically meet at that interface: living ownership on one side, defensible acoustics on the other.
In practice, mid-market Australian PCBUs win when ownership is visible, methods match the question being asked, and evidence survives the next roster change without a scavenger hunt through old inboxes and forgotten shared drives.
Keep the tone factual: hierarchy of control first, competent measurement second, and records that a new supervisor can find on day one.

Closing
A risk register earns trust when it is owned, current, and connected to real controls. For noise, that often means knowing when a generic row is enough—and when an acoustic consultant should put numbers behind the plan. Get ownership right first; then expertise lands where it can change the plant, not only the paperwork.
