Overview
The VIacoustics Sound Power Level Estimation system is a low cost system for conducting sound power level measurements on products and equipment for product development and pre-compliance testing. The Sound Power Level Estimation System uses 4 microphones and a 4 channels of data acquisition to create an economical system for the estimating the sound power level emissions of products and equipment.
The system includes a host signal processing unit running our Trident multi-channel software application. Four (4) GRAS microphones and a microphone calibrator are included, with all the cables, connectors, holders and stands needed to arrange them into a sound power measurement array. A MSExcel template for calculation and reporting of sound power level results is included.
For products and equipment with sound pressure level emissions greater than 20 dBA, our low cost Sound Power Level Estimation System uses the National Instruments cDAQ data acquisition device and the GRAS Sound and Vibration model 40PH microphones. All hardware and software is certificated for compliance with *IEC-61672 Class 2 sound level meter requirements.
For small products, the Sound Power Level Estimation System can include and be integrated into a Small Device Test Chamber, for a complete turnkey system. For larger products, the Sound Power Level Estimation System can be used for in-situ measurements or in an Acoustic Test Chamber designed to meet the unique needs of your product and your host site.
Features
VIacoustics supplies Small Device Test Chambers from ETS-Lindgren as part of its standard and custom test systems for product noise emission measurement.
Small Device Test Chambers are available in four standard sizes that address most small device measurement applications.

Services
VIacoustics turnkey measurement systems are built in a working acoustics laboratory and are fully assembled, calibrated and tested for plug and play operation when the arrive at your site. This includes assembly of system hardware, installation of drivers and software, system configuration and calibration and providing labeled cables and connectors for full system function on installation.
VIacoustics turnkey measurement systems are shipped to your site ready for final installation and plug-and-play operation. Our services include unpacking and setting up the equipment, system initialization, calibration, and training of facility staff to use the system.
VIacoustics turnkey measurement systems include post installation support via telephone, e-mail and/or online support sessions. Our support staff is highly knowledgeable on acoustic measurement standards and practices, National Instruments digital signal analyzers, and all of the VIacoustics software.
VIacoustics can offer you a wide variety of acoustic and quality system consulting services that can help you build an acoustic measurement program from a basic sound level measurement to a fully accredited test laboratory. And, we can also help you make your products quieter and sound better to your customers. Here’s just a few of the consulting services we typically provide to our clients.
Acoustic Consulting on Product Noise – Understanding of product specifications, regulatory requirements, test methods, and basic acoustic principals as it relates to your product, equipment, or situation. Many clients who are experiencing acoustic noise emission requirements for the first time need these services just to understand the basics of the technology and the measurements required.
Acoustic Consulting on Acoustic Measurements and Laboratory Design – We’ve been involved in the construction and instrumentation of literally hundreds of acoustic measurement laboratories throughout the world for the past 30+ years. Some were basic acoustic measurement test benches in small companies and some were the largest, accredited test laboratories in the US. We can help you plan for what you need to build an acoustics program in your company that will meet your needs.
Acoustic Consulting for Product Noise Control – Working with David Nelson of Nelson Acoustics, one of the leading noise control consultants and sound quality experts in the US, VIacoustics can offer you acoustic consulting services that will help you reduce, control and engineer the sounds that come from your product to meet regulatory requirements, product specifications or customer acceptance criteria. David employs common sense engineering principals to help you meet your product noise goals. His extensive work in psychoacoustics and sound quality help our customers learn how to make acoustic engineering a product advantage that pays for itself in increased sales and profit margins.
ISO 17025 Quality System Consulting for Acoustics Laboratories – Jeff G. Schmitt, P.E., Principal Engineer for VIacoustics has a strong background and experience in helping acoustics laboratories prepared for accreditation under ISO 17025. He serves as an acoustics laboratory assessor for the US National Institute of Standards and Technology, National Voluntary Laboratory Accreditation Program (NVLAP) and has been trained in the concepts of ISO 17025 quality systems. From his early involvement with the first NVLAP accredited acoustics laboratory in the US, to the US Government and private sector companies he has helped, Jeff has been involved in the accreditation of numerous acoustics laboratories in the US. Jeff takes a very practical and organized approach to developing quality systems that fit the needs of the laboratory, rather it be a small company operation or a large government laboratory.
