    Acoustic Noise Chamber Testing, Design, and Refurbishment

    The engineers at the Huntsville laboratory specialize in a wide range of acoustics testing, including high intensity acoustic noise and progressive wave acoustic noise. The engineers at the lab provide support, testing, and engineering services for the design of specialized test equipment, including the WAS 3000 and WAS 5000 Acoustic Noise Generators, Many industries require the accurate measurement of the level of sound that products emit in order to adequately protect technicians, users and others in close proximity to the noise the equipment produces.

    At NTS Huntsville, we regularly conduct acoustic noise testing to meet the requirements of regulatory bodies like OSHA, telecommunications companies like AT&T and Verizon, medical equipment regulators, and business equipment regulators. We also help companies comply with the standardization of military and defense equipment. Industry standards that cover acoustic noise testing include: ISO 9296, ISO 7779, ISO 3744, GR-63-CORE, ETSI EN 300 753, IEC 60601, and MIL-STD-1474D (previously MIL-STD-740).

    International Approvals and Certification

    Getting your product into international markets can be difficult—particularly during a pandemic. Plus, geopolitical dynamics fundamentally change the type of markings you might need to get your product into a new country. In the UK, for example, Brexit means that you will need a UKCA marking to sell your product. Meanwhile, new criteria for your product in Russia, Ukraine, India, Brazil, Egypt, and the United Arab Emirates is necessary. Are you aware of these changes?  The good news is that a team of experts is dedicated to helping you track every minor change to help you secure regulatory approval in global markets. The goal is to streamline the process for entering international markets to avoid delays and duplicative testing. The international approval services include the following:
