Recognise these problems?

  • Pipework shaking or vibrating near compressors, pumps or valves

  • Repeated cracking of welds, brackets or structural supports

  • Machinery that cannot run reliably at design speed or load

  • Equipment failing vibration acceptance tests or certification

  • Structures or platforms resonating when machines operate

  • Plant derating because vibration risk is too high

  • Noise complaints caused by vibration transmitted through structures

These symptoms usually indicate an unresolved vibration or structural dynamics problem that needs proper engineering diagnosis rather than repeated trial-and-error repairs.

Vibration & Structural Dynamics

We investigate machinery, pipework and structures that are vibrating excessively, cracking in service, failing acceptance limits or operating below intended capacity.

Our work combines on-site measurement, structural dynamics analysis and practical mechanical engineering to identify the governing mechanism and develop modifications that remove the cause of the problem.

  • Machinery vibration and resonance problems

  • Piping vibration and fatigue risk

  • Structural flexibility and dynamic amplification

  • Operating restrictions linked to vibration risk

  • Verification of proposed engineering modifications

Noise, Structure-Borne Sound & Vibroacoustics

Many industrial noise problems originate from vibration generated by rotating machinery, process equipment or structural systems.

We examine how vibration passes through the source → path → receiver chain and develop engineering measures to reduce radiated and transmitted noise.

  • Structure-borne sound investigations

  • Vibration-driven noise control

  • Transfer Path Analysis (TPA)

  • Isolation, stiffness and damping improvements

  • Support for noise and compliance-related engineering problems

Our Engineering Process

Diagnose: Identify the Governing Mechanism

We establish why the vibration, fatigue, instability or vibration-driven noise problem exists, so corrective action is targeted at the real cause.

Measure: Establish the Real Behaviour

On-site measurement reveals how machinery, structures and connected systems are actually responding in operation.

Analyse: Understand Dynamic Behaviour

Engineering analysis links the measured response to resonance, flexibility, forcing, coupling or machine–structure interaction.

Design: Engineer the Corrective Modification

Once the governing mechanism is understood, practical engineering changes can be developed to remove the cause of the problem.

Support: Ensure Successful Implementation

Where modifications are required, we support implementation and verification so the solution performs reliably in service.








Who are we?


Director-Led Engineering. No Sales Layer.

Environmentally Sound provides specialist mechanical engineering support for complex vibration, structural dynamics, and machinery reliability problems. Unlike larger consultancies where work is often delegated to junior staff, every project is personally led by Paul Schmitz.



Paul Schmitz, CEng MIMechE, MIoA

  • Chartered Mechanical Engineer with 30 years in mechanical manufacturing, machining, and structural dynamics.
  • Proven Aerospace Authority: Refined equipment to pass vibration certification on 15 aircraft frames.
  • Evidence-Led Approach: Specialist in linking on-site measurement with advanced FEA modelling to identify the governing mechanism behind a failure.

When you engage Environmentally Sound, you get direct access to three decades of diagnostic experience. External specialists are only engaged when it adds specific value, keeping your solutions lean, technically robust, and validated by data.


Results Proven by Case Studies

  • Quarry Plant: Eliminated severe resonance with targeted isolation, improving safety and structural stability.
  • API 619 Compliance: FEA-driven frame stiffening shifted natural frequencies and passed third-party audit.
  • Structure-Borne Sound, Belgium: Removed 58.33 Hz transmission through custom isolation and resolved the complaint.
  • Commercial Property Monitoring: A two-week vibration survey identified the cause and supported mitigation.

Why Choose Environmentally Sound

  • Direct access to a Chartered Engineer — no sales layer
  • Diagnosis through to engineered modification and verification
  • Evidence-led work based on measurement, analysis and real operating behaviour
  • Advanced toolchain including FEA, EMA/FRF, on-site monitoring, model updating and verification
“If it isn’t measured and proven, it isn’t fixed. Our solutions are validated by data, not assumptions.”
