Our Approach - From Problem to Proven Solution
We begin with the mechanical cause, not just the symptom. Using calibrated measurement and model-based analysis, we design practical, durable solutions that meet defined acceptance criteria and compliance standards.
Investigate: Root-cause analysis defines “what good looks like”.
Test & Measure: Traceable instrumentation for baseline and post-change data.
Analyse: FEA, modal/EMA, order tracking and diagnostics inform design choices.
Design: Stiffness, damping and isolation engineered for performance and reliability.
Support: Implementation, commissioning and verification against targets.
Our Proven Engineering Process
Environmentally Sound Limited follow a repeatable, evidence-led process to solve mechanical, vibration and noise challenges. This five-stage approach defines how we deliver verified, measurable results.
1) Investigate
Define the problem, performance criteria and boundaries.
Apply engineering judgement and experience to identify likely causes.
Related: Failure Analysis & Root Cause
2) Test & Measure
Collect baseline vibration, strain and displacement data using calibrated instrumentation.
Compare pre- and post-change conditions to quantify improvements.
Related: Measurement & Testing
3) Analyse
Model mechanical behaviour with FEA (static, modal, harmonic, random response).
Update models to match measured data (EMA correlation, FRF overlays).
Related: Finite Element Analysis (FEA)
4) Design
Engineer stiffness, damping and isolation into practical, durable solutions.
Validate design updates against acceptance criteria and compliance standards.

Process Optimisation & Lean Engineering
Environmentally Sound Limited apply Lean Engineering principles to complex mechanical systems to improve efficiency, eliminate waste, and enhance quality. Our approach integrates mechanical design insight, measurement-led analysis, and process engineering to deliver sustainable performance improvements in manufacturing and assembly environments.
In modern production systems, mechanical precision alone is not enough - quality and sustainability depend on process stability. ESL combine root cause analysis, workflow mapping, and data-driven predictive methods to identify where mechanical variation, assembly error, or inefficiency originates. We then engineer improvements to both design and process, achieving measurable, verified results.
Our Process Optimisation Services
Lean engineering audits for assembly and test processes
Data-driven defect prediction and prevention
Process redesign for quality, reliability, and throughput
Integration of measurement systems and feedback loops
Waste reduction strategies aligned with net-zero objectives
