Why pre-screen acoustics engineers before the technical panel
Nobody complains about decibels in an office. They complain that they can hear every word of a conversation three desks away, which is a speech intelligibility problem, and adding absorption alone rarely fixes it. Engineers worth hiring measure distraction distance and privacy indices rather than sound level. A short screen asks what they measured before and after a change.
What actually matters when screening Workspace Acoustics Engineer candidates
- 01
Technical depth
Check command of open plan metrics: distraction distance and spatial decay per ISO 3382-3, NC/RC background curves, STI/STIPA, absorption coefficients and NRC ratings for ceiling and screen products.
- 02
Work that shipped
Probe delivered workspace projects: huddle rooms, Teams or Zoom certified rooms, sound masking commissioning with LogiSon or Biamp, WELL sound feature credits, before and after measured results.
- 03
Diagnosis under uncertainty
Test how they chase complaints with no obvious cause: HVAC tonal noise, flanking through plenums, echo on far-end calls, floor vibration from gyms or plant.
- 04
Working across the org
Assess dealings with architects, AV integrators, facilities and workplace strategy teams when acoustic treatment conflicts with exposed slab aesthetics or budget cuts.
Pre-screening questions to ask Workspace Acoustics Engineer candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Spaces they improved
3 questions01Can you provide examples of projects where you improved acoustic conditions?
Listen forSpaces where measurements improved and occupants reported a difference, with both recorded.
Assessments delivered with no implementation, or improvement claimed without measurement afterwards.
02Describe a challenging acoustic problem and how you resolved it.
Listen forA real diagnosis where the obvious fix was wrong, with what the measurements actually revealed.
Absorption added as a default response, or the underlying transmission path never identified.
03Can you discuss your experience with room acoustics and sound isolation?
Listen forIsolation and absorption distinguished clearly, with flanking paths considered rather than only partitions.
Isolation and absorption confused, or flanking transmission never investigated.
The right measurements
3 questions04What methods do you use for sound measurement and analysis?
Listen forSpeech intelligibility and privacy indicators measured, alongside reverberation time and background noise level.
Sound pressure level measured alone, or no speech privacy indicator used in an office context.
05Can you describe your experience with acoustic modelling and simulation?
Listen forModels validated against measurements in comparable completed spaces rather than trusted directly.
Model output used as evidence, or predictions never compared against a finished space.
06How do you measure and evaluate the success of an improvement project?
Listen forBefore and after measurement combined with occupant feedback, with both reported honestly.
Success assessed by the measures installed, or no measurement taken after completion.
Open plan and calls
3 questions07What strategies do you use to improve conditions in open-plan offices?
Listen forDistraction distance addressed through layout, absorption and masking together rather than one alone.
Absorption panels proposed as the whole answer, or layout treated as fixed and unchangeable.
08What do you consider when designing for hybrid and remote meeting spaces?
Listen forMicrophone pickup and reverberation addressed for remote participants, not just for people in the room.
Rooms treated as in-person spaces, or remote participant experience never considered.
09What experience do you have with noise control and mitigation?
Listen forSource, path and receiver all considered, with control at source preferred where it is achievable.
Treatment applied at the receiver only, or noise sources never addressed directly.
Verified afterwards
3 questions10How do you ensure compliance with acoustic standards and regulation?
Listen forRelevant standards named for the building type, with testing performed to demonstrate compliance.
Standards referenced generally, or compliance claimed without any verification testing.
11How do you handle client expectations on acoustic projects?
Listen forRealistic outcomes set out early, including what cannot be fixed within the budget or the building.
Outcomes promised that the space cannot deliver, or budget limits not discussed upfront.
12How do you collaborate with other engineers and designers on projects?
Listen forInvolvement at design stage where acoustics is cheap to fix, with interface details agreed early.
Involvement only after complaints, or acoustic requirements raised after construction detailing.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Technical depth
35%5Quotes target rD and D2,S values, distinguishes NRC from Sabine absorption, and links NC curves to conferencing microphone pickup.
Work that shipped
30%5Names specific fit-outs, cites measured reverberation and privacy index improvements, and shows masking tuning curves signed off by the client.
Diagnosis under uncertainty
20%5Describes structured narrowing using narrowband spectra, intensity or accelerometer data, and near/far-end call recordings before proposing a fix.
Working across the org
15%5Recounts trade-offs negotiated with named disciplines, offering alternative treatment options with cost and performance consequences stated plainly.
Nobody complains about decibels; they complain they can hear every word three desks away. A one-way video screen asks what was measured.

Process basics
How long should a pre-screening round for this role take?
Fifteen minutes across eight to ten questions, answered async. Enough to establish spaces they improved, test their measurement approach, and check verification and client work.
How much should modelling experience count?
Less than measurement. Models are useful for design, but a workspace problem is diagnosed by measuring what is actually happening in the occupied space rather than by simulating it.
Evaluating answers
What is the strongest signal when screening this role?
Measuring speech privacy rather than sound level. Engineers who solve office problems use intelligibility indicators. Anyone quoting decibel levels has measured the thing nobody complains about.
How do I judge whether their fixes work?
Ask what was measured after the change and whether occupants noticed. Real answers include both. Anyone who did not measure afterwards does not know whether the money achieved anything.
