Mechanical assets often continue operating while internal conditions change. Friction, load shifts, misalignment, and wear can develop quietly, leaving teams uncertain about whether an asset remains stable or is gradually moving toward failure.
Asset condition monitoring is therefore not about confirming faults after they occur, but about forming a judgment: is this asset changing in a way that requires future intervention?
Condition monitoring often starts too late
By the time deterioration becomes obvious, options are often limited. Many condition monitoring practices rely on contact-based measurements, fixed thresholds, or periodic checks that surface issues late in the failure cycle.
In environments with many distributed, noisy, hazardous, or hard-to-reach assets, this makes it difficult to form a consistent and timely picture of asset condition. As a result, teams are often pushed into reactive decisions instead of planned intervention.
How acoustic asset condition monitoring works
Mechanical deterioration is usually a process, not an event. As components wear, changes in friction, load, alignment, or contact between surfaces begin to alter how an asset behaves, often while performance remains unchanged.
These behavioural changes affect the sound an asset produces, particularly at higher frequencies. Friction, micro‑impacts, and surface interactions associated with early wear often generate acoustic signature in the ultrasonic range, before shifts in vibration or other indicators become apparent.
Acoustic asset condition monitoring focuses on interpreting how these sound patterns develop over time. Instead of confirming a single fault, teams gain insight into whether asset condition is stable, gradually degrading, or approaching a point where intervention should be planned. Because the method is non‑intrusive and non‑destructive, asset condition can be assessed repeatedly without disassembly, direct contact, or interruption to operation.
Where this solution fits?
Industrial operations
For industrial sites focused on reliability, maintenance, and efficiency, including food and beverage, automotive, production lines, utilities, datacenters, and general manufacturing.
Hazardous environments
For hazardous and regulated sites where safety, certification, and uptime are critical, including oil and gas, chemical processing, hydrogen, energy, and utility infrastructure.
Why teams use this approach?
Understand the asset
Changes in sound behaviour give additional insight into how assets are evolving, helping teams judge whether equipment remains stable or is moving toward failure.
Non‑intrusive assessments
It allow teams to evaluate asset condition without frequent contact‑based measurements or operational disruption.
Better decisions
Condition insights can be documented and used to support prioritisation, planning, and condition‑based maintenance reporting.
Plan intervention
By focusing on progression rather than isolated faults, teams can plan maintenance based on condition instead of reacting to alarms or breakdowns.
Proof from the field
Deterioration detected earlier during tests
In controlled tests on contaminated bearings run to end of life, Sorama acoustic monitoring identified signs of mechanical deterioration before traditional vibration‑based monitoring indicated a developing issue.
The evaluation compared acoustic and vibration methods across the bearing life cycle to assess when each approach first revealed meaningful change. The results showed that acoustic monitoring provided insight into deterioration approximately 17% earlier than vibration measurements.
This earlier insight gives maintenance teams more time to assess risk, plan intervention, and schedule maintenance before deterioration progresses to unplanned downtime or more extensive repair.
Some teams need fast handheld checks during maintenance rounds. Others need ongoing monitoring in critical or hazardous areas. We support both approaches, so teams can choose the inspection setup that fits their environment, workflow, and level of risk.
Acoustic asset condition monitoring helps teams assess asset health by identifying abnormal sound linked to developing faults.
What kinds of issues can this approach help identify?
This approach can help identify mechanical anomalies, early signs of wear, bearing-related issues, and other faults that produce an audible or ultrasonic sound signature.
How does acoustic inspection support predictive maintenance?
It helps teams identify issues, localize the source more clearly, and plan maintenance before problems lead to failure or unplanned downtime.
Can asset condition monitoring be used in hazardous environments?
Yes. Sorama supports inspection in hazardous and regulated environments with ATEX- and IECEx-certified products.
