Minimizing sound starts with the things around us. As such, manufacturers of products look to
reduce their sound levels. The reduction of sound from a product has many additional opportunities
that are not available when treating systems found on ships or factories. NCE provides consulting,
testing and noise control treatment design as described below.
Services offered to product developers, manufacturers and system integrators are:
PRODUCT NOISE TESTING
Before you decide to reduce the sound of your product, it is essential to know what the current
sound levels are. NCE can conduct accurate sound level measurements at your facility or in some
case ours. While we are not a test lab, NCE follows rigorous standards for sound measurement. All
surveys are conducted with instruments calibrated to NIST standards within one year of any work
being done. NCE will perform the sound measurements to either your company's internal standards or
published Federal (ANSI, ASA) or international (ISO) standards. NCE can also help determine what
standards to which your products should be tested.
PRODUCT NOISE REQUIREMENT DETERMINATION
Product noise reduction should only be undertaken after two pieces of information are available.
The first is the level of sound from the product. The second is the required or desired level of
sound. NCE can measure the first part (as described above). The second part may come from federal
regulations, industry standards, client's requests, but NCE can also help to determine an
appropriate level of sound from your product.
PRODUCT NOISE ASSESSMENT/REDUCTION
When product noise levels and the required level are know, the task of determining the need noise
reduction can start. NCE will evaluate your product to determine type and paths of the controlling
noise. Type of noise include: aerodynamic, mechanical, electrical noise. Paths include: airborne,
structureborne or fluidborne. Both the type of noise and path will determine the appropriate
treatments. NCE will acoustically dissect your product which allows recommendations of appropriate
type of treatments. In addition, in some cases small changes to internal components can reduce
sound without addition of actual noise control materials. NCE always looks for least expensive
approaches for the best reduction in sound.
PROTOTYPING NOISE CONTROL TREATMENTS
After the appropriate treatments have been determined, NCE can take product noise reduction a step
further by prototyping one of the products to demonstrate actual noise reduction. This can be done
in our office or your facility. NCE will provide a bill of materials, installation drawings and
instructions as desired when the effort is complete.
