What project managers should look for beyond the noise report
July 20, 2026An acoustic assessment submitted as part of a project’s design documentation is a technical document. It contains noise predictions, comparisons against applicable criteria, and mitigation recommendations. For acoustic engineers, it… -
Why tonality in modern mechanical plant is becoming a project risk
July 17, 2026Tonal noise from mechanical plant is not a new engineering problem. It has been present in HVAC and industrial equipment for as long as rotating machinery has been used to… -
The cost of late-stage acoustic changes on Tier One projects
July 13, 2026On many major construction projects, acoustic engineering is engaged early enough to satisfy planning approval, but not early enough to influence design. Equipment selections proceed under the assumption that acoustic… -
Designing acoustic infrastructure that can scale with future capacity
July 10, 2026Most large data centre, industrial, and energy infrastructure projects are designed with staged expansion in mind. Site masterplans show future building footprints, additional mechanical plant bays, expanded cooling infrastructure, and… -
Why acoustic design and acoustic compliance are not the same thing
July 6, 2026Meeting a noise criterion and delivering a good acoustic outcome are related but not equivalent. The distinction is not semantic. It has practical consequences for occupant experience, long-term asset performance,… -

Weather, water ingress and acoustic integrity
June 22, 2026Acoustic performance is frequently assessed at a point in time, typically at commissioning or during a formal noise survey, and the result is compared against a design target or regulatory… -
Duct-borne noise transmission in complex networks
June 19, 2026In a simple duct system, noise propagation follows a clear path: a fan generates acoustic energy, which propagates through the duct toward the terminal or discharge point, attenuated by lining,… -
Why tonal noise drives complaints more than overall dB(A)
June 15, 2026Environmental noise assessments for mechanical plant typically centre on the overall A-weighted sound pressure level, expressed in dB(A), at defined receiver locations. The dB(A) metric is well established, widely understood… -
Isolation strategies for plantrooms in multi-storey buildings
June 12, 2026In multi-storey buildings where mechanical plant is located adjacent to, above, or below occupied spaces, structure-borne noise frequently becomes the dominant acoustic design challenge. Airborne noise from plant rooms can… -
Integrating CFD and acoustic modelling for plant design
June 8, 2026Acoustic modelling and computational fluid dynamics (CFD) have long been treated as independent disciplines in the design of mechanical plant and building services systems. Acoustic engineers characterise noise sources and… -
Balancing pressure drop and acoustic performance
June 5, 2026The relationship between acoustic performance and pressure drop in ducted attenuation systems is one of the more consequential trade-offs in mechanical services engineering. More acoustic media means more insertion loss,… -
Designing attenuation for performance below 125 Hz
June 1, 2026Low-frequency noise below 125 Hz presents engineering challenges that standard attenuation approaches are not designed to address. While mid-to-high-frequency performance is relatively straightforward to achieve with conventional splitter attenuators, performance… -
