Turning up the Volume

Sydney-based global company Cochlear Ltd designs and manufactures innovative implantable hearing products, including the world-leading Nucleus® cochlear implants.

NMI’s expertise in delivering trusted measurement services provides the level of accuracy needed by medical device companies such as Cochlear to underpin their extremely tight manufacturing quality and reliability processes.

• In 2011 Cochlear asked NMI to provide highly accurate measurements of the platinum–iridium wires used in the Nucleus® cochlear implants. Cochlear required an accuracy of measurement that was not attainable by any NATA-accredited laboratories. NMI developed and validated several new measurement techniques, achieving an accuracy level within 0.4 μm, and subsequently gave Cochlear technical advice on the appropriate use and limitations of their measurement instrumentation.
• In 2013 Cochlear required very precise measurements of vacuum pressure which NMI was able to supply based on recent development activities in establishing vacuum pressure standards.
• Cochlear staff have attended our training courses on estimating measurement uncertainty and geometric dimensioning and tolerancing.

NMI looks forward to a long-term partnership with Cochlear as it continues to develop its world-leading innovative solutions for hearing disorders.
