What is the purpose of acoustic testing?

 


In acoustics, sound, disturbance, and vibration are studied. The allowable levels of acoustic noise vary depending on the type of technology. Acoustical testing aids the determination of these parameters by product makers from diverse industries. Organizations evaluate how well your product will work in the real world.

Sounds are essential for delivering the correct message about such a product's characteristics and functionality. Manufacturing is also being forced to lower noise levels due to laws and competitive factors. Throughout the development process, designers want effective tools for designing, refining, and validating prototypes.

The evaluation of Industrial soundproofing outputs from devices under test is known as acoustic noise measurement. Acoustic noise examination is needed in many product markets to safeguard technicians' and customers' hearing. Using the experience of our experts, we create innovative products with such a striking acoustic character. For instance,

  1. Equipment which produces irritating or loud sounds and beeping can readily be recognised all throughout a house or apartment.
  1. Acoustic sound tests for military defence items are required to verify acceptable sound levels. This enables appropriate verbal transmission while minimising adversary acoustic detection.
  1. Many various types of devices must have their acoustic sound emission levels stated in order to be lawfully marketed.
  1. Acoustic noise validation is essential for goods used in corporate headquarters, data centres, client residences, and outdoor plant areas in the telecommunication sector.

A sound power measurement apparatus

The sound-power values must be determined using high-quality measuring equipment. The ISO 3740 and ISO 9614 sets of specifications each have their own set of system requirements. Microphones, intensity probes, cables, filtration, and calibrators are common pieces of sound power measurement equipment. Our acoustical testing systems combine simplicity, productivity, and experience. Here are a few of our ideas:


 

Designing Active Sound

Active audio design is taken to a new level with the digitalization of the powertrain. This technique can eliminate bothersome interior acoustic phenomena in hybrid vehicles. Other technologies can produce exterior sounds to inform other road users. This audio signature ought to be immediately distinguishable and brand-bound.

Artificial audio in ICE automobiles was previously used primarily for audio quality and emotional reasons. This system provides an alternative means of providing continuous audio input to drivers of electric vehicles. Active background music is also a workable option for the recently enacted AVAS requirement in electric vehicles.

In modern electric automobiles, sound design has become a practical and important part of the driving experience. As acoustic developers and designers, the demands for automotive sound, whether technical or emotive, pose new problems. We provide a full toolkit to help you manage them holistically.


 

Wind Tunnel Aero-acoustic Measurements

Automobile wind tunnel testing would be a useful tool in the automobile industry for measuring and optimising wind noise following comprehensive CFD and 3-dimensional vibro-acoustic modelling. Wind tunnels are still in high demand as the electricity movement continues. To balance demand and expense, Acoustic Testing in Sydney facilities have to improve their products and services.

To deal with demand against cost, wind tunnel research facilities require enhanced techniques. There seems to be a trend toward increasingly advanced, high-channel-count test procedures. New insights into increasing vehicle aero-acoustic performances could be gained by merging several techniques.
