Environmentally Sound — Chartered Mechanical & Acoustic Engineers Specialists in Vibration, Noise & Mechanical Design


Mechanical Engineering

Mechanical design underpinned by structural dynamics and proven by test. From concept to refinement, we engineer products and systems to meet demanding reliability, fatigue, and compliance requirements in real operating environments.

Vibration Engineering

Nearly three decades of experience solving vibration problems. Using diagnostics, FEA/EMA, modal testing, and API 619 compliance, we design isolation and structural improvements that ensure machines operate safely, quietly, and without costly downtime.

Noise & Acoustics

Independent consultants delivering BS 4142, BS 8233, BS 5228, and ISO-compliant assessments. From environmental surveys to acoustic modelling and mitigation, we deliver evidence-based solutions trusted by councils, industry, and developers.

Engineering Management

Management built on engineering standards. We optimise processes, improve compliance, and align delivery with net-zero frameworks — ensuring leaner, more resilient operations without compromising technical integrity.

Failure & Process Analysis

Measurement-led investigations of mechanical, vibration, and noise failures. Our root-cause analysis identifies the true fault mechanism and provides clear, actionable solutions that restore reliability and prevent recurrence.

Design Refinement

When products or systems fail certification or performance, we apply structural dynamics expertise to refine the design. Our redesigns minimise rework, reduce programme delays, and deliver components proven by test.

Implementation & Support

From installation and commissioning to monitoring and validation, we oversee solutions through to operation. Our involvement ensures that fixes remain effective and compliant throughout the lifecycle.

Problem Solving

We measure, analyse, design, and verify — not trial-and-error. Our structured troubleshooting delivers reliable, evidence-based solutions that cut cost, risk, and time to compliance.

Industries Served

From planning approvals to protecting multimillion-pound assets, Environmentally Sound delivers measurement, analysis, and design proven by compliance and real-world performance.

Led by a Chartered Engineer with 40 Years’ Experience

Paul Schmitz, CEng MIMechE, MIoA, leads every project and ensures accountability from investigation through validation.

  • 40 years in mechanical manufacturing and machining

  • 29 years specialising in vibration, structural dynamics, and noise control

  • Design improvements on 15 aircraft frames — refined to pass vibration certification

Our director-led delivery ensures consistent quality. Trusted specialists are engaged only when they add real value, keeping solutions lean and effective.

Results Proven by Case Studies

  • Quarry Plant: Eliminated severe resonance with targeted isolation — improving safety and 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; complaint resolved.

  • Commercial Property Monitoring: Two-week vibration survey identified root cause; mitigation reduced disturbance and liability.

Why Choose Environmentally Sound
