Your product or service may not be accepted by the marketplace unless it meets or exceeds certain performance expectations. HEI can ensure that your product measures up. Using standards-compliant objective and subjective testing strategies, we determine a product's conformance with design criteria and whether or not it will satisfy customer expectations. Our independent quality assessments verify marketplace potential in an objective, credible manner — our test suites may include usability and acceptability tests in addition to the more common subjective and objective tests.

Performance verification is especially important for equipment using new technologies. Potential purchasers may require mean opinion score (MOS) performance-verification test results from an independent agency prior to making a commitment. HEI provides standards-compliant testing using established or customized test programs for a product or application.

We provide a wide range of usability, acceptability, objective and subjective evaluations and tests, including ITU-T mean opinion score (MOS) and other P.800 tests such as ACR, CCR, CMOS, DCR, DMOS, QRDM, TM and VIRIS. We also provide perceptual speech quality measurements (PSQM) conforming to P.50, P.830 and P.861 as needed.

Following testing, our staff works with your marketing, product development and design teams to fine tune the product's performance. Also, we ensure that client marketing and sales brochures and supporting materials accurately describe and promote the product quality.

Whatever your product and test program objectives, whether your need is for initial product testing or long-term quality-of-service (QoS) performance monitoring, HEI can provide the most useful, relevant and cost-effective suite of tests.
