Acoustic Testing

Acoustic Testing

Acoustic sound testing in the field is supported by our acoustic technologies and on-site facilities including our Innovation and Acoustic Laboratories. Our acoustic testing processes allow for the quick and reliable identification and treatment of noise problems to identify high performance solutions for the Vehicle and Industrial Noise Control markets. Ventac has invested in top of the range test equipment and sound analysis tools. The tools are designed to objectively measure and present the different acoustics criteria as the human ear actually hears the sound.

Ventac’s field testing services can be conducted both on-site at Ventac’s facilities or at our customers sites to facilitate the development of a Noise Reduction Plan (NRP) for our Industrial Noise customers or to support our Vehicle Acoustic Test Program. Our sound testing processes follow the most relevant industry testing standards and we can guarantee a fast and effective outcome with our testing generally taking between 1-2 days. As part of our partnership approach we aim to educate and facilitate our customers technical teams on acoustics and best practice when it comes to developing and designing high quality noise control solutions.

Ventac constantly strives to work along-side our customers to find the most effective noise control solution. Through this partnership, we will ensure that the solutions identified are in line with the needs and demands of our customer’s problems so that they can see the benefits of installing a Ventac solution

Vehicle Noise Testing Capabilities

Ventac’s field-testing and noise source analysis can be conducted on complex noise sources including vehicles and heavy machinery. This testing is carried out using precision test equipment and extensive engineering experience from our Acoustics team who specialize in the field. Ventac’s field testing services are conducted in support of our Vehicle Acoustic Test Program for effective noise control solution identification.

As part of the assessment, noise control problems can be assessed and prototype acoustic solutions can be quickly supplied for testing on the vehicle or machinery. This testing procedure is supported by Ventac’s advanced noise source identification techniques, which include sound intensity equipment and highly effective Acoustic Camera arrays.

Tests conducted can include beamforming measurements and the fast identification of mid to high range frequency noise sources, nearfield holography measurements for detailed analysis of noise radiating from a source at a given frequency and sound power level measurements that are conducted where noise is measured in controlled conditions to give accurate results.

This Ventac approach is used to combine high-tech test techniques with hands on engineering experience to quickly identify solutions for all vehicle and machinery noise problems.

Building and Industrial Noise Testing Capabilities

Ventac field testing services for the Industrial Noise market are used for the development of noise control solutions. Noise assessments are conducted at our customer’s sites for the development of a Noise Reduction Plan (NRP) to support solution identification and is conducted using our advanced noise source identification techniques. Product development and testing services are also available within our Innovation and Acoustic Laboratories for the building and construction industries.

Ventac’s on-site testing capabilities for the development of Building and Industrial product solutions include:

• The acoustic performance of a wall or partition construction can be tested to measure airborne noise and sound insulation properties in accordance with the relevant industry test standards. The controlled acoustic environment of Ventac’s chambers allows for the exact measurement of sound energy lost across the test samples.
• Floor constructions can be tested for airborne sound and impact sound insulation. Ventac’s testing facilities can be used to assess the sound energy that is transmitted structurally to determine how a floor will respond to noise coming from sources such as footsteps, furniture movement, etc. Building components such as doors can also be tested.
• Sound insertion loss measurements for ventilation components can be conducted on duct components such as attenuators. Sound insulation measurements can be conducted for product applications such as acoustic louvres. Ventac’s additional facilities can also conduct tests on air-flow noise measurements for components such as louvres and grills and sound power levels of fans to include case breakout, inlet and outlet noise.

Materials Testing

Because all of Ventac’s materials are tested within our Innovation and Acoustic Laboratories, we understand how they perform at different frequencies. Through understanding their acoustic properties, Ventac can then tailor a bespoke solution for each of our customers. Additionally, all our products are selected to withstand their environments and include properties such as heat resistance and thermal requirements. All of our parts are designed specifically by matching the material to the noise source for each of our customers applications.

All of our solutions are validated with their end application in mind, may it be a bus floor or an engine bay to give the most accurate results. Developing our solutions in this way guarantees a high performance result and solutions that work in conjunction with our clients vehicles.
