About Us — Environmentally Sound Limited
Director-led Chartered Engineers — Investigate. Measure. Analyse. Design. Support.
Why our consultancy services matter
Clear accountability: you deal directly with the Director and Technical Lead (Chartered Engineer).
Evidence-led engineering: decisions based on disciplined measurement, analysis and verification — not opinion.
Fast, practical delivery: efficient scoping, focused investigation, and solutions that can be implemented.
Flexible support: a small specialist team can be mobilised quickly when projects need extra capacity.
Integrity first: if we’re not the right fit for your problem, we’ll tell you early and clearly.
Accountable technical leadership
Paul Schmitz MBA CEng MIMechE MIoA — Director & Technical Lead.
Environmentally Sound Limited is a director-led specialist engineering consultancy built around two pillars:
Vibration & Dynamics and
Noise & Compliance.
Paul has 40 years’ experience in manufacturing and engineering, including
30 years specialising in vibration and structural dynamics — the root cause of many unwanted noise,
fatigue and reliability problems.
Mechanical engineering + acoustics: joined-up problem solving
Acoustic engineering (including vibration and noise) is closely linked to mechanical engineering, because real-world problems
rarely stay in one box: vibration drives noise, noise creates compliance risk, and both can indicate fatigue and structural issues.
That’s why our work is structured to find root cause, prove behaviour with data, and deliver solutions that stand up to scrutiny:
investigation, measurement, analysis, design, and verification.
How we started
Hello, I’m Paul Schmitz, Director of Environmentally Sound Limited — welcome to our website.
“Forty years ago I first stepped into an engineering company. Since then I’ve dedicated my career to mechanical engineering,
specialising in mechanical vibration — the most common source of unwanted noise.”
If you can’t find what you need here, call us on 01908 643 433.
How we work — summary of our proven process
From acquisition to analysis, accuracy starts with the engineer who captures the data. Our structured yet adaptable approach builds
to one outcome: a proven solution against agreed criteria.
Investigate — on-site fact-finding; agree success criteria and compliance targets.
Measure — deliberate, disciplined measurements by the same engineer who analyses the data.
Analyse — turn measured data into engineering insight; refine models to match reality.
Design — engineer robust, compliant solutions validated before implementation.
Support — implement, verify against the original criteria, and provide in-service support.

Professional practice & technical governance
We aim to be easy to trust because our work is evidence-led and auditable. In practice that means:
clear scope, assumptions, success criteria and boundaries agreed at the start
documented measurement approach and traceable reporting
analysis and models anchored to real measured behaviour (not “best guesses”)
solutions designed to be buildable, practical, and verifiable against defined criteria
transparent limitations where constraints or unknowns exist
Why the name is apt
The name was coined while performing environmental testing of aircraft equipment and machinery. These programmes required not just
running tests (e.g., RTCA/DO-160 and MIL-STD-810), but improving products so they passed.
The predominant failures were vibration-related. By diagnosing and redesigning products to endure vibration, we turned compliance into
real-world compatibility — the essence of being Environmentally Sound.
What is environmental testing?
Subjecting equipment and systems to simulated real-world conditions to verify reliable operation. Typical categories include:
Standards define methods and criteria; the real expertise comes from redesigning products to overcome failures — particularly where
vibration is involved.
Who we are
We are a consultancy proficient in solving problems in dynamics, vibration, noise and mechanical engineering. Our hands-on experience spans
aerospace, defence, microelectronics, industrial manufacturing and construction, with successfully completed projects across the UK,
Ireland, Belgium, Germany and Scandinavia.
Our values
We believe in integrity and quality. We deliver high-quality work while providing an effective and financially efficient service — and we
will always be candid about what is achievable within your constraints.
What to do next
If you have an underperforming product — or a new requirement — we can help with investigation, measurement & testing, analysis, design, and ongoing support, verified against agreed criteria.
