Mechanical Engineers and Acoustic Engineers
Acoustic engineering - including vibration & noise - is a sub-discipline of mechanical engineering. Together they let us investigate problems, solve them, and - where required - implement and install mitigation across machinery, structures, and diverse environments.
How We Started
Hello, I am 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.”

The Meaning of “Environmentally Sound”
Environmentally Sound combines two words: environment (the conditions in which people, equipment and activities operate) and sound (strong, reliable, durable, fit for purpose).
In our context, it means solutions that are:
environmentally healthy
environmentally durable
environmentally reliable
environmentally resilient
environmentally compatible
environmentally compliant
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 to RTCA/DO-160 and MIL-STD-810, but improving the 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 in vibration.
Who We Are
We are a consultancy proficient in solving problems in noise, vibration 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, and will always deliver high-quality work while providing an effective and financially efficient service.
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.
Investigate - on-site fact-finding; agree success criteria and compliance targets.
Test & 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.

Noise
Why?
Noise is the most common pollution in residential and industrial areas.
How?
We conduct attended and unattended surveys; compile professional reports for local councils and the Environment Agency; and support planning applications.
What?
From BS 4142 assessments to wider environmental noise impact assessments and modelling, we can help. See Case Studies.
Vibration
Why?
Vibration is the source of most unwanted noise and is directly related to fatigue. By design control and/or isolation, we reduce noise at source by optimising structural dynamics.
What?
We’ve measured and monitored vibration for 27+ years across automotive, industrial, oil & gas, and aerospace - using results to improve designs to meet regulations and standards. See case studies.
Mechanical Engineers
Why?
Mechanical engineering provides the foundation for designing machines and equipment, including structural dynamics under vibrational conditions.
We design and engineer products for their environment - especially when conditions are severe.
What?
Our origins are in environmental testing of equipment and instrumentation for automotive and aerospace. When products didn’t pass, we found and implemented design solutions to meet acceptance criteria.
What to Do Next?
Combining experience, expertise and consultancy in noise, vibration and mechanical engineering, we resolve problems and design products to be truly Environmentally Sound.
If you have an underperforming product - or a new requirement - we can help with design, analysis and testing. For noise concerns or planning permissions, call 01908 643 433.
