Competent consultancy on machine noise, acoustics and vibrations. We can help you with machine noise measurement for CE labelling and are accredited to perform measurements of noise and vibrations.

Accredited noise and vibration measurements and documentation

We offer consultancy services, measurement and documentation of acoustic noise and vibration from machines in accordance with applicable directives, executive orders and international standards. Noise and vibration measurements are performed in our laboratories or on-site with machinery suppliers and manufacturers.

We perform measurements of noise and vibrations under DANAK accreditation no. 100. This is your guarantee that the reports meet both national and international requirements.

Use our advice on machine noise and vibrations during product development

A noise and vibration-dampened product can provide market advantages.

We offer advice and measurement of acoustic noise and vibrations from machines from the conceptual phase of prototype development until the finished product.

During development, we can help you use the right materials and test the noise characteristics before you use the materials to manufacture the product. We can also help optimise the sound quality and sound design, creating and composing just the right sound for your product.

Sound insulation, audio radiation, structural dynamics, methods of calculation, testing and verification are also issues we can help you with.

Machine noise measurements and dampening

CE labelling of machinery under the Machinery Noise Directive 

The Danish Environmental Protection Agency has designated FORCE Technology as a notified body to carry out noise measurements for the use of CE labelling under the executive order on machinery noise. This executive order implements Directive 2000/14/EC of the European Parliament and the Council, “The Machinery Noise Directive".

Machinery subject to the executive order may be marketed or put into service only if it complies with rules on maximum noise levels or noise labelling. There are noise limits for a wide range of machinery, for example, lawnmowers, forklift trucks, excavator loaders, dozers and similar construction machinery.

We perform a range of other types of noise declarations and noise measurements at the operator level, which is part of our extensive DANAK accreditation. 

Measuring, calculating, cancelling and dampening machine noise

We begin a project by mapping out the noise of the product using our advanced measuring equipment to document the sound output from various product sub-sources.

Based on this, we define the order of priority of the most dominant sources of noise. This makes it possible to draw up the necessary noise-cancelling measures to ensure an optimum solution.

Examples of noise-cancelling measures can be:

  • Design of noise shielding
  • Calculations of noise dampeners for ventilation and exhaust systems
  • Replacement of components for quieter types
  • Elastic mounting of machinery and piping systems

Vibration measurements for a good working environment

Vibrations are shocks. The Danish Working Environment Authority has rules on how vibrations affect people if they occur in the working environment. It is important to be able to measure and analyse the impact of vibrations to enable a good working environment.

We have the equipment to measure and report hand-arm vibrations and full-body vibrations in accordance with the rules of the Working Environment Authority.

Assessment of vibrations in machinery and equipment to protect production

Vibrations occur everywhere where machines are in operation. Imbalanced machines in particular give rise to vibrations that lead to poor operating conditions in production. Vibrations can be passed on to other parts of the process or cause annoying noise.

You can get advice about assessment of the condition of machinery and equipment – and we provide solutions so that production is not unnecessarily disturbed.

Calculation and advice on outdoor vibrations to ensure comfort and safety

Vibrations from construction machinery or railroads can affect nearby buildings. If the vibrations are strong, they may cause discomfort to the people who are in the adjacent buildings or damage to buildings. Therefore, the Danish Environmental Protection Agency has set limits on vibrations within buildings and low-frequency noise caused by vibration influences.

Contractors, employers, residents and insurance companies can get help with studies of vibration influences. This enables you to:

  • Document whether a limit is met or exceeded
  • Monitor vibrations for shorter or longer periods
  • Make preliminary studies, e.g. related to EIA analyses (environmental assessments)
  • Problem-solve or prevent damage to buildings

Extensive experience with vibrations

You can benefit from our accumulated experience regarding vibrations. We have developed a tool to calculate how the vibrations propagate and are accredited to measure vibrations in the external environment. When assessing the risk of building damage due to vibrations, we follow, for example, DIN 4150-3.
