Environmentally Sound Limited

Environmentally Sound Limited improve living and working environments. Additionally, we design and improve products, machinery and equipment to:

  • function unnoticed and blend in with their natural environments, and

  • operate robustly and resiliently in extreme environments.

  • meeting current and future environmental legislations and regulations

To achieve this high specification for product design for both in the natural environment and extreme environments, we established specialist groups.

The groups are:

  • vibration consultants

  • noise consultants and

  • acoustic consultants

The mechanical vibration and acoustics consultancies support each other to design and improve products, equipment and machinery for both the natural and extreme environments.

This approach ensures high quality products delivered through efficient processes using the highest expertise and experience in these engineering disciplines.

Making environmentally sound products; hence the name Environmentally Sound!

Who is a typical customer of Environmentally Sound Limited

Our mechanical a engineering consultancyservices>are for anybody that wants a product designed or has performance related issues with their products, machinery and equipment.

Why are our consultancy services important to you?

  • Our extensive experience and knowledge in investigative engineering of products failures has given us unprecedented ability to design robust and reliable products.

  • Creative minds that think outside the box for innovative designs that give you improved product performance and an increased return on investment.

  • Well versed in model updating using measured data to improve numerical models and analysis, that has provided us with an efficient process to robust new designs.

  • Extensive experience in development testing and certification testing has aided us to a trialled and tested process to satisfactory product performance.

  • Proven track record for increasing product and engineering processes has delivered a cost effective appraoch for your product quality goal.

  • We have a broad knowledge and experience of engineering across several engineering disciplines and operational management that enables us to communicate to engineers across different disciplines, senior management and shareholders.

All these above is what is put into the design of a product, equipment and machine. Ensuring that the complete process, from design requirements right though to production, are efficient and cost effective.

Our mechanical engineering services are sub-divided into:

  • Innovation

  • Product or machinery design

  • Product improvement

  • Analysis of numerical models

  • Failure investigation

  • Performance and field measurements

  • Corrective designs

  • Low volume manufacturing

  • Product development

  • Product testing

  • Product quality improvement

  • Process improvement for design and manufacturing

  • Equipment, plant and machinery maintenance


Product Innovationfor us is to find the most cost effective improved design, one that increases the return on your investment.

Product design

Designing a productor machine that has improved quality, reduced processes and utilises design criteria of the company's best performing in-service products.

Creative minds and out of the box thinking gives us the edge over most mechanical engineering consultancies.

And through this approach, we are able to design simple and uncomplicated designs using the basics of mechanical engineering, which can easily and cost effectively be manufactured.

Design improvement

This then takes us back in the cycle to product design, and all the findings are then fed into the new design concept.


This is typical analysis performed on the model of the product, equipment or machine to ensure the product will endure the environment in which it will operate and operate reliably and resiliently.

Measurements and instrumenting products and structures

To understand the behaviour of the product in the field, during development and product testing, we instrument the product with necessary transducers andrecordthe response in order to understand the actual behaviour.

This then gives us true understanding of the product and is used to compare with the analysis results and to update the numerical model.


Simulation of the physical product is possible with updating the analysis model with the product's physical environmental and structural behaviour.


Development of new designs and product by performing environmental testing and functional testing of the product.


Product certification as for aircraft equipment, which follows a stringent testing regime.

Investigative engineering

Investigation of product failures within the field or on test. This helps us redesign or improve the product to operate within its environment.

Problem solving

This relates to investigative engineering and is initiated once the cause of failure of a product is determined.

Engineering process improvement

As very experienced mechanical engineering consultants, we know the most efficient approach to get a product to market. Eradicating the 'luxury' and unnecessary tasks from the mandatory tasks. Consequently achieving an efficient process.

Increase product quality

From individual components to complete assemblies, we have a successful track record of increasing product quality.

Mechanical Vibration Consultants

The mechanical vibration consultants support the acoustics consultants and the mechanical engineering consultants in resolving noise issues and helping with designing products for respective environmental conditions and all matters relating tovibration.

Vibration Engineering

This service is shared with the mechanical engineers to design products, machinery and equipment for theextreme environment where vibration is dominant. The vibration engineers support the acoustics consultants when products and machinery are designed for thenatural environment.

Condition Monitoring

We provide avibration based condition monitoringservice to monitor and record the vibration content of rotating equipment to prevent in-service failure and unnecessary downtime.

Vibration Isolation

Mechanical vibration isolationis required to prevent vibration from going into neighbouring structures, as the vibration could be harmful to those structure and the vibrations could become structure-borne and consequently radiate noise from the internal walls.

Vibration Data Acquisition and Analysis

From vibration acquisition, the vibration analysis of the data is paramount to understand what is occurring in the structure. To analyse the vibration data, we turn to:

These give us the valuable information of how the products, machinery, equipment and/or structures behave under vibration.

Vibration Testing

As experienced vibration consultants invibration testing, our emphasis is on designing for vibration environments.

With a wealth of resolving equipment and instrumentation failures during vibration testing, our experience is vital to help companies develop products for vibration environments as in the aerospace, automotive, industrial, and marine sectors.

With this wealth of vibration testing experience, we are able to design vibration test fixtures for vibration testing, with an approach that will minimise the payload for the shaker.

You can also read more about what we've done in the vibration blog.

Noise Consultants

Our noise department works closely with vibration and structural dynamics professionals in resolvingnoiseviolations, as most noise recorded with BS4142 and BS8233 is noise from mechanical vibration.

This gives us the ability to mitigate mechanical noise as we are experienced mechanical engineers versed in structural dynamics and how to manipulate the structure for more favourable vibration behaviour.

The British Standards that we use regularly

  • BS4142 - Methods for rating and assessing industrial and commercial sound

  • BS8233 - Guidance on sound insulation and noise reduction for buildings

  • BS7445 - Description and measurement ofenvironmental noise. Guide to quantities and procedures

  • BS5228 - Code of practice for noise and vibration control on construction and open sites. Noise

  • BS6472 - Guide to evaluation of human exposure tovibration in buildings

Acoustic Consultants

Acoustic consulting suits our portfolio well, as it complements our involvement in vibration noise, which expands our expertise in resolving noise and acoustic issues.

After all, noise is the result of vibration.
