Adding to its line-up of acoustic sensors and test fixtures, GRAS Sound & Vibration (part of Axiometrix Solutions) has released four further configuration options for its 45CC test fixture series, intended at R&D applications and for production line testing.
With these new configurations, GRAS offers ten variations that target different testing needs and are configurable for any headphone test set-up and test environment, with a mouth simulator option for all of them. Building on the malleability of the existing configurations, the new 45CC versions maintain their ease-of-use, and add the possibility for more realistic testing that enables R&D and production engineers to benchmark and align tests across a production line.
The new 45CC products (45CC-14, 45CC-15, 45CC-16 and 45CC-17) enable headphone and headset manufacturers to obtain accurate, repeatable and reproducible test results, dual-channel testing, and multiple configuration options.
The new product configurations comprise: 45CC-14 (which includes externally polarised IEC 60318-4 ear simulators and anthropometric pinnae); 45CC-15 (which includes prepolarised IEC 60318-4 ear simulators and anthropometric pinnae); 45CC-16 (which includes externally polarised IEC 60318-4 high-frequency ear simulators and anthropometric pinnae) and 45CC-17 (which includes prepolarised IEC 60318-4 high-frequency ear simulators and anthropometric pinnae).
‘There has long been a need for better alignment of tests across R&D and Production,’ says GRAS Sound & Vibration VP of Business Development, Niels Kjærgaard. ‘The 45CC platform already has a solid footprint in the testing market and we are responding to a rising demand from leading headphone and headset manufacturers to offer a versatile text fixture, which in an easy and inexpensive way, allows R&D and production engineers to develop the design of tests, and to validate and align these tests in the production line setting.’
The four new versions are optimised for test scenarios that require or benefit from realistic human-like acoustic loading and ear geometry when testing any headphone or earphone type (around ear, on ear, in ear, and insert). The 45CC-16 and 45CC-17 are designed for test scenarios up to 20kHz.
Coupled with the latest configurations, GRAS currently offers the only affordable desktop solution in the market that includes high-frequency ear simulators and anthropometric pinnae. Production of the new 45CC variants is underway and orders can be placed now with GRAS´ standard delivery of six weeks. For more information, please visit GRASacoustics.com/45CC.
